Now we’re building the delivery of (almost) everything and you’ll find us in over 500 cities in 30 countries around the world. In 2022 we joined forces with DoorDash and together we keep on dreaming big and expanding across the globe.

Working at Wolt isn’t always easy, but it’s definitely exciting. Here you’ll learn more, build more, and ship more than in most other companies. You’ll be challenged a lot, but also have a lot of fun on the way. So, if you’re a self-starter with drive and entrepreneurial spirit, this could be the ride of your life.

We are seeking a forward-thinking, AI-first leader to shape and drive the evolution of Marketing Innovation across the organization. Sitting within the Marketing function, this role is responsible for defining how AI transforms marketing-from how we plan and create, to how we execute, personalize, and scale.

As Global Head of Marketing Innovation, you will lead the transition from traditional marketing operations and tooling toward AI-powered workflows, agent-driven automation, and intelligent decision systems.

What we offer

This is a rare opportunity to get under the hood of a massive growth engine and actually build the tools that make it run. You won’t just be managing existing software; you’ll be the strategic architect responsible for moving us away from manual, “copy paste” work toward a smart, automated system powered by AI and real time data.

You will have the mandate to bridge the gap between Marketing, Product and Engineering, making sure our tech stack is a competitive advantage rather than a bottleneck.

Our Commitment to Diversity and Inclusion

We’re committed to growing and empowering a more inclusive community within our company, industry, and cities. That’s why we hire and cultivate diverse teams of people from all backgrounds, experiences, and perspectives.

About hyperexponential (hx)

At hyperexponential, we’re building the AI-powered platform that enables the world’s most critical decisions in a $7 trillion industry, which risks to take, and how to price them. These are the decisions that shape real-world outcomes: whether rockets successfully launch into space, autonomous vehicles make it to market, or communities recover after major storms.

Until now, insurance has been making billion-dollar decisions using outdated tools. We’re changing that. Our platform brings together data, AI, and human expertise to give insurers the fastest path from submission to decision - helping them move faster, act smarter, and take on more risk with confidence.

Backed by a16z, Highland Europe, and Battery Ventures, we’re scaling globally - already trusted by nearly 50 of the world’s largest insurers, with zero churn and billions in premiums flowing through hx.

What began as a single product in one market has rapidly evolved into a multi-product, multi-territory platform powering every stage of pricing and underwriting. AI is at the core of what we do - from building the world’s first domain-specific AI peer programmer for insurance (think GitHub Copilot with a PhD in actuarial science) to shaping agentic workflows that reinvent how this industry operates.

What makes hx different is the people who build it. Here, impact isn’t tied to title or tenure; it’s defined by the challenges you take on and the discipline you bring. Surrounded by peers who stretch you, you’ll do the best, hardest work of your life in a company engineered to endure.

If that sounds like you, join us in building what comes next.

About the Analytics team

Engineering at hx drives every breakthrough that transforms how insurers make billion-dollar decisions. Our Analytics team sits at the cutting edge of this mission, building the data systems that unlock the full value of complex insurance datasets. We’re turning raw portfolio data into actionable insights that help underwriters and actuaries make smarter, faster decisions on risks worth billions.

As a Senior Backend Engineer in the Analytics team, you’ll architect and build the foundational data systems that power next-generation insurance analytics. This is greenfield territory - you’ll be designing distributed data solutions from the ground up, creating scalable ingestion pipelines, and building the infrastructure that turns complex insurance data into competitive advantage for our customers.

You’ll work at the intersection of complex engineering challenges and real business impact, collaborating with sharp product and UX minds to create data-driven experiences that fundamentally change how insurers understand and optimise their risk portfolios. If you love solving hard technical problems while seeing direct customer impact, this is where you’ll thrive.

What You’ll Be Doing

  • Build scalable data systems in Kotlin that enable insurers to ingest, process, and explore complex datasets, turning months of manual analysis into real-time insights that drive billion-dollar risk decisions.
  • Design distributed analytics infrastructure on AWS using Terraform, creating robust, cloud native systems that handle enterprise scale data volumes while maintaining reliability and performance.
  • Deliver customer facing analytics features that transform how users understand and optimise risk modelling, building intuitive interfaces for complex portfolio analytics that were previously impossible.
  • Drive technical innovation in data architecture, piloting emerging technologies and AI/ML approaches that continuously improve the analytics experience and unlock new capabilities for customers.
  • Collaborate across disciplines with Product, UX, and Engineering teams to translate complex business requirements into elegant technical solutions that balance powerful functionality with usability.
  • Elevate system quality through robust architecture decisions, comprehensive testing, and clear documentation that makes complex data systems maintainable and scalable as the team grows.

What You’ll Need to Have Done

  • Built production backend systems with proven experience as a polyglot engineer, ideally with strong Kotlin skills and the ability to work effectively across multiple languages and tech stacks.
  • Delivered scalable cloud infrastructure using AWS and infrastructure as code tools like Terraform, with hands on experience building distributed systems that handle real world data volumes.
  • Developed data warehousing solutions with hands on experience building ETL pipelines, data modelling, and orchestration workflows using modern tools (e.g., dbt, Airflow, Spark), demonstrating the ability to transform raw data into reliable, performant analytics infrastructure that supports business decision making at scale.
  • Collaborated effectively across teams to deliver features that customers actually use, with evidence of translating business requirements into technical solutions that drive measurable impact.
  • Maintained high code quality standards with a commitment to clean, well documented, maintainable systems and the discipline to build infrastructure that scales with business growth.
  • Demonstrated curiosity about emerging technologies, particularly around data processing, analytics platforms, and AI/ML tools that can enhance developer productivity and unlock new customer value.

You’re Unlikely To Thrive Here If

  • You prefer working with well established data systems rather than building foundational analytics infrastructure from scratch in a rapidly evolving environment.
  • You’re more comfortable focusing on purely technical challenges than understanding the business context and customer impact of the data systems you’re building.
  • You’re not excited by the complexity that comes with distributed data processing, enterprise scale systems, and the technical depth required for analytics platforms.

Reading our Culture Document leaves you feeling neutral rather than energised, hx may not be the place where you’ll do your best work. We’re building something that asks for commitment and conviction, and we want you to feel excited by the opportunity to grow with us.

Compensation

Our Mission

Human time and effort is the rarest thing in the universe. The fact that so many people hate what they do for work is a disaster on so many levels. How many people live quiet lives of misery? How many generational talents do we miss due to circumstance?

Dex’s mission is to close the gap between Talent & Opportunity; we believe that work, and being productive, is part of the human condition, that regardless of AI, human passion, ingenuity and a desire to do things means that work will always exist.

We are building Dex to create a future where technology helps every individual to understand their strengths, interests and unique abilities, and to connect with opportunities where they can thrive, because more people doing things they love leads to a better, happier and more productive world.

We’re starting by connecting the world’s most ambitious software engineers with the companies that deserve them.

About Dex

Dex is backed by a16z Speedrun, Concept Ventures and angels from OpenAI, Wise, ElevenLabs, Meta’s board, and many more.

We’re an ambitious, direct and kind group of people, we value authenticity, ambition and people who make things happen.

We’re a team of 12 (and growing) based in London (Borough). We work together 3-ish times a week because we value in person time, but we’re person centric and flexible. We hire adults who can manage their own schedules.

About the Role

  • ML engineering role, not a research role, not a prompt engineering role. You understand the underlying mechanics: how embeddings encode meaning, how attention shapes retrieval, and how to build and evaluate representations that power matching and ranking systems.
  • You use LLMs where they’re the right tool, but your first instinct is to understand the problem at a model level, not to reach for an API.
  • The work is concrete: building a system that takes a new role and stack ranks the entire candidate database against it in seconds.
  • You own the representations and scoring models that sit at the core of how Dex connects engineers with companies.
  • The matchmaking engine you build here is the foundation that powers everything that comes next-candidate facing products, automated outreach, smarter sourcing-so you’re building for durability, not just the immediate use case.
  • Your ML judgment is backed by solid engineering execution.

What You’ll Do

  • Own the matchmaking engine-build and improve the AI driven talent matching system; design representations, scoring models, and instrumentation from the ground up.
  • Work with embeddings and retrieval-build and evaluate embedding models, vector search, and semantic retrieval systems that power candidate to role matching.
  • Design and run evaluations-build practical eval frameworks for model behaviour and output quality; make rollout safety and failure handling first class concerns.
  • Contribute to agent and LLM systems-work on the voice agent backend and LLM pipelines with a model level understanding of what’s actually happening.
  • Ship reliable backend services-build production grade Python services, not prototypes; handle errors, retries, latency, and observability as standard.

About you

  • ML foundations-you understand how embeddings, attention, and retrieval systems work at a model level; you can reason about representations, not just API responses.
  • Production judgment-you know when to use an LLM, when to use classical ML, and when to use neither; you’ve made these calls in production, not just in notebooks.
  • Evaluation and guardrails mindset-you build evals before things go wrong; you design failure handling and rollout safety into systems from the start.
  • Backend execution strength-you ship reliable, maintainable services; your track record shows production ML systems, not just impressive demos.

Strong technical depth in:

  • Python backend (FastAPI or equivalent, async patterns, Postgres, Redis)
  • Embeddings, vector search, and semantic retrieval (building and evaluating, not just calling)
  • ML model evaluation-Metrics design, offline/online eval, failure analysis
  • LLM integration with model level understanding (attention, context windows, trade offs)

Nice to Have

  • Experience with recommendation systems, ranking models, or candidate/item matching
  • Classical ML background (supervised/unsupervised, feature engineering, gradient boosting)
  • Experience with voice agents or real time audio pipelines
  • Familiarity with Pydantic AI or similar agent frameworks
  • Experience in recruiting tech or marketplace systems

Why this is a great opportunity

Dex represents an opportunity to join a well funded, early stage business that is solving a real and relatable problem in a gigantic market.

This is an opportunity to build a brand from the early stages in a team that cares deeply about brand and design. We work in a market that has an absolute dearth of intentional brands and designs; we want to stand out from that.

There will be a generational company built in this space, we believe it’s going to be Dex.

What we offer

  • Above market salary-you’re building a world class team and believe pay should match that ambition.
  • Significant equity- we want this to be the last job you ‘have’ to take.
  • Full private healthcare & dental-because life happens and we want to support you.
  • Fertility benefits & enhanced parental support
  • Gym membership & wellness benefits
  • Claude tokens-lots and lots of Claude tokens
  • Regular socials, offsites, and an annual trip
  • MacBook Pro + team kit
  • “Whatever you need” approach to tools and support
