About the job

Lead Software Engineer

Stealth AI Fintech Startup | London | Hybrid (3 days on-site)

We’re hiring on behalf of a venture-backed fintech building an AI-driven platform transforming how investors analyse and manage alternative assets such as private equity and private credit.

The MVP is built. Funding is secured from experienced fintech founders and senior figures in financial services. Now the focus is scaling the product properly, with strong architecture, clean engineering standards, and production-grade systems.

They’re looking for a Lead Engineer who wants to be deeply hands-on and shape the technical foundation from within the codebase.

The Role

This is not a management-heavy position. You won’t be spending your days in planning meetings or overseeing layers of engineers.

You’ll be coding daily.

You’ll design and evolve the architecture of an AI-native SaaS platform that automates due diligence and investment workflows in a legacy financial industry.

You’ll set the technical standard by doing the work: writing clean systems, making pragmatic architectural decisions, and solving hard problems alongside the team.

What You’ll Be Doing

You’ll lead the architecture of an AI-driven investment intelligence platform while staying deeply hands-on across the entire stack, from frontend UX to backend services, AI integrations, and core infrastructure. Working closely with the CTO, data scientists, and product leadership, you’ll help shape both the technical direction and the product itself.

You’ll build and mentor a small, elite engineering team, setting a high technical bar through example while driving strategy around scalability, security, and reliability. Along the way, you’ll explore and integrate emerging AI frameworks, tools, and blockchain technologies to keep the platform at the cutting edge.

What We’re Looking For

*

5+ years professional software engineering experience

*

2+ years operating at senior/lead level

*

Strong ownership mindset, you don’t wait to be told

*

Comfortable building in ambiguity

*

Node.js, React & TypeScript

*

Python for AI automation and workflows

*

Microservices & distributed systems

*

AI/LLM frameworks (LangChain, OpenAI API, Vertex, LiteLLM)

*

GCP & DevOps best practices

*

PostgreSQL and relational modelling

*

Event-driven systems (Kafka, Pub/Sub) + MongoDB

*

Experience shipping production SaaS platforms

Nice to Have

*

RAG, autonomous agents, MCP

*

Exposure to blockchain or tokenisation frameworks

*

Security, cryptography or distributed systems knowledge

*

Fintech or asset management experience

Why Join

*

Build a technically ambitious AI product in fintech

*

Stay fully hands-on while influencing core architecture

*

Work alongside an experienced CTO and high-calibre team

*

Real ownership, your technical decisions directly shape the platform

*

High-trust, low-bureaucracy environment where output matters

Were hiring an experienced, hands-on Tech Lead to take ownership of day-to-day technical delivery as a growing product platform moves from early-stage build into a robust, scalable system.

This is a builder-led leadership role. Youll remain close to the code while setting direction, standards, and pace for a small but growing engineering team.

This role suits someone who enjoys ownership, shipping real product, and making pragmatic decisions in fast-moving environments.

The role

You will take responsibility for delivering key product areas end-to-end, from technical design through to release and iteration. Early on, youll be relied upon to write and ship critical parts of the system yourself while helping establish strong engineering foundations.

This is not a role focused on meetings, ticket administration, or status reporting. Delivery and quality come first.

What youll be doing

• Owning delivery across core product areas: feasibility, design, build, release, and iteration
• Staying hands-on in the codebase, particularly in the early stages
• Providing day-to-day technical leadership, mentoring engineers and unblocking progress
• Setting engineering standards around quality, performance, testing, and reliability
• Making sound technical trade-offs across frontend, backend, and data workflows
• Driving improvements in platform foundations including performance, observability, security, and cost awareness
• Establishing lightweight delivery cadence with clear definitions of done and reliable releases
• Collaborating closely with product managers, designers, and senior stakeholders

What were looking for

• 710+ years experience building and shipping production software in product-led environments

• Strong full-stack engineering fundamentals, including:

  • TypeScript / Node.js backend systems
  • React + TypeScript on the frontend
  • PostgreSQL and data modelling (geospatial or mapping experience a bonus)

• Proven experience owning projects end-to-end and shipping to production repeatedly

• Experience building data-heavy B2B SaaS products (dashboards, workflows, permissions, internal tooling)

• Strong product mindset with a high bar for usability, accessibility, and UI quality

• Comfortable working with incomplete requirements and turning ambiguity into delivery

• Experience leading or mentoring small engineering teams

• A builder-leader mindset: able to write high-quality code while raising the bar for others

Nice to have

• Experience in high-integrity data environments (e.g. compliance, reporting, analytics platforms)
• Experience setting up early-stage engineering foundations (CI/CD, environments, logging/metrics)

Role details

• Full-time, permanent position
• Remote working (UK or European time zones)
• £95,000 per annum
• Equity participation available
• Opportunity to play a key technical leadership role as the platform and team scale
