Our client is the leader in their field and with pipeline opportunities that would enable them to double their revenue by the end of 2028. To support this, they are in the early stages of a bold digital transformation to improve operational processes and procedures and to modernise systems and practices so that they can deliver quality at pace.

Currently the team are transitioning from traditional software application development using C#, Blazer and SQL Server integrating with Dynamics Business Central, and the Data team provide analytics and insights using SAS, MicroStrategy and Power BI.

The new model is to continue with a .NET tech stack, but the team will build and run so developing applications and deploying with DevSecOps. The Data team will also deploy solutions and will move to Fabric, Databricks or Snowflake.

With a Data Architect now in place, the focus is to recruit a Technical Lead to lead the software engineering function.

This role will formerly move towards a Head of Engineering & Platform position but will remain hands on. This is leading by doing and mentoring so you will still be building full stack C# applications and deploying with DevOps but leading others too. There are 7 Software Engineers, an Automation Tester, Scrum Master, DevOps, Infra Engineers and Service Desk Team.

You need to have experience of leading end to end software development including design, build, testing, deployment and support. The Service Desk team need to work closely with the build and deployment resources so that they can support products more effectively.

Key areas of responsibility:

Define and execute the engineering strategy across Azure cloud, integration, and legacy modernisation, aligned to the clients long-term digital roadmap.

Design and deliver cloud-native solutions that scale efficiently, perform reliably, and integrate seamlessly across business functions.

Lead by example in Azure DevSecOps: create and manage pipelines (YAML), infrastructure-as-code (Bicep, Terraform), and container orchestration (AKS, Docker).

Embed engineering best practice: implement CI/CD, code quality gates, automated testing, and observability from build to production.

Guide platform evolution: re-engineer legacy .NET and SQL systems into modular, API-driven architectures.

Build and empower teams: mentor full-stack, DevOps, and Automation Test engineers fostering autonomy, innovation, and accountability.

Champion security and reliability by design: integrate compliance, performance, and monitoring into every stage of delivery.

Collaborate widely: partner with Product, Data, and Infrastructure teams to ensure alignment between technology capability and commercial goals.

Drive innovation: pilot emerging technologies (AI, automation, data services) that improve efficiency and insight.

Tech Stack seeking:

Full Stack Developer; Design and Build with C#, JavaScript Library (React.js bonus), API Development, SQL Server/Backend Development including ETL/Integration

Azure DevOps (Repos, Pipelines, Boards, Artifacts, Test Plans),

CI/CD automation, gated releases, and environment governance

Infrastructure-as-Code (Bicep, ARM, Terraform)

Containerisation (Docker, AKS) and serverless (Azure Functions)

Monitoring and observability (Application Insights, Log Analytics)

Secrets management and vulnerability scanning (Key Vault, SonarQube, OWASP)

Microservices and event-driven design (Service Bus, Event Grid, Kafka)

Domain-Driven Design (DDD) principles

Overall experience:

8+ years in software engineering, with deep full-stack and cloud experience.

Proven record of leading end to end engineering teams through modernisation or platform rebuilds (Design, build, test, deploy, support)

Azure DevOps and enterprise-scale CI/CD. (DevSecOps a bonus)

Excellent architectural judgement; balancing delivery speed, stability, and cost efficiency. Good understanding of SOLID principles

Strong communication and leadership presence able to influence peers and executives alike. This role needs high energy and to take the team on a journey

A continuous learner, passionate about automation, clean code, and scalable design.

This is an exciting time to join a digital transformation in the early stages to lead and influence their transition to modern practices and systems to help them scale and grow at pace.

The role will ideally be Peterborough 2 days a week and 3 days remote. However this can also be based out of London (City) but with Peterborough for 2 days per month for 4 months then London 1 day a week and Peterborough 1 day some weeks. Travel from London + overnight stays in Peterborough will be paid.

AI Engineer (Generative & Agentic AI)

Permanent

Location: London (onsite twice a week)

Salary: £75,000 - £85,000 Per Annum D.O.E

Build intelligent systems that solve real enterprise problems:

We’re looking for an AI Engineer who wants to do more than just plug into APIs, someone who wants to own the build, shape intelligent systems, and bring advanced GenAI and Agentic AI solutions into real-world production.

If you’re motivated by tackling messy enterprise problems, not just experimenting with models, this is a role where you’ll build systems that genuinely change how organisations operate.

Why this role exists:

Enterprises are past the experimentation phase. They’re asking harder questions:

  • How do we make GenAI stable, scalable, and safe?
  • How do we move from prototypes to production?
  • How do we integrate AI into existing products and workflows?

You’ll be the engineer who takes these questions and turns them into working, impactful AI systems, not just research pieces or demo-ware.

This role is ideal for someone who thrives on building, iterating, and owning AI solutions end-to-end.

The Role:

As an AI Engineer, you’ll be responsible for designing, building, and deploying production-grade AI systems in complex enterprise environments.

You will:

  • Build and deploy GenAI, RAG, and Agentic AI systems that solve real business challenges
  • Develop robust pipelines, services, and integrations that turn models into usable products
  • Work across front-end, back-end, and data layers to deliver complete, functioning AI solutions
  • Collaborate with architects, data scientists, and product stakeholders to shape solutions and define delivery paths
  • Take ownership of performance, scalability, and maintainability of AI components
  • Continuously experiment, improve, and bring new ideas forward, without heavy process slowing you down

This isn’t a research role and it’s not “keep the lights on.” It’s product-driven engineering where you ship real systems into production.

Key Responsibilities:

AI System Development

  • Build and optimise AI models and pipelines
  • Implement RAG, agentic workflows, and advanced reasoning techniques
  • Deploy LLM-driven features into real products

Full-Stack & Platform Engineering

  • Develop APIs, backend services, data flows, and integration layers
  • Contribute to UI/UX when needed as part of end-to-end delivery
  • Ensure clean, scalable engineering across the stack

MLOps / LLMOps

  • Own the deployment, monitoring, and iteration of AI systems
  • Use modern tooling to ensure models and pipelines are reliable, observable, and repeatable

Collaboration

  • Work closely with cross-functional teams to identify opportunities and translate them into robust engineering solutions
  • Provide technical input into architecture, design discussions, and delivery planning

What We’re Looking For:

Core Experience:

  • Strong Python engineering skills and experience delivering production AI/ML systems
  • Hands-on experience with LLMs, RAG, vector databases, and GenAI frameworks
  • Experience deploying solutions on cloud platforms (AWS, Azure, or GCP)
  • Familiarity with LangChain, LlamaIndex, or agentic frameworks is highly valuable
  • Strong grounding in software engineering best practices (testing, versioning, CI/CD, scalability)

Mindset & Behaviours:

  • Seek ownership, not just tasks
  • Enjoy solving real user and business problems, not just model optimisation
  • Thrive in environments where they can experiment and move quickly
  • Communicate clearly with both technical and non-technical stakeholders
  • Want to see their work in production, being used by real people

Why Join?

  • Work on impactful AI programmes that go beyond prototypes
  • Build meaningful, high-value systems that people actually use
  • Work with modern GenAI tools, approaches, and delivery models
  • Collaborate with experienced architects, engineers, and innovators
  • Strong investment in engineering excellence, innovation, and personal development

If you want to build AI systems that matter, not just experiment with models, this is your next move.
