Job description

Technical Team Lead / Lead Software Engineer (Platform)

Technical Team Lead

London (Hybrid: 2-3 days per week) £90,000-£110,000 + strong benefits

Our client is a fast‑scaling, well‑funded technology company building a platform used by some of the UK's best‑known brands. They're now looking for a hands‑on Technical Team Lead to drive the next phase of their engineering evolution.

This is a rare opportunity to own a major platform migration, influence long‑term technical strategy, and step into a leadership role with a clear progression path toward CTO as the business scales.

If you love building high‑quality software at scale, leading talented engineers, and making meaningful architectural decisions - this role is for you.

The Opportunity

As Technical Team Lead, you'll combine around 60% hands‑on coding with strong technical leadership. You'll guide a growing team of engineers, define engineering standards, and work closely with partner agencies to deliver a modern, scalable SaaS platform.

You'll also play a pivotal role in a strategic migration away from legacy Service Fabric architecture toward a Kubernetes‑based backend, helping to define the future technical foundation of the entire product suite.

This is a high‑impact role where your decisions will genuinely shape the company's technology and growth trajectory.

What You'll Be Doing

• Leading and mentoring a team of 3-6 engineers, with significant growth planned
• Remaining deeply hands‑on, contributing ~60% of your time to coding
• Defining and owning the technical strategy for the Connect 2.0 platform migration
• Architecting scalable backend systems using Kubernetes
• Driving modern front‑end development with React
• Setting engineering standards and best practices across internal teams and partner agencies
• Making key decisions across architecture, integrations, frameworks, and cloud infrastructure
• Collaborating closely with product and leadership to influence roadmap and direction
• Helping build a secure, high‑performance, modern SaaS platform

What You'll Bring

• Strong engineering background across backend (Kubernetes) and frontend (React)
• Experience leading teams or mentoring engineers in a senior capacity
• Proven experience designing, building, and scaling modern SaaS platforms
• Solid cloud experience (Azure preferred)
• Ability to translate business goals into scalable technical solutions
• Confident communicator who works well across teams and with external partners
• Pragmatic, hands‑on mindset with a passion for quality engineering
• Architectural experience - or clear ambition to move into a broader strategic role

Tech Stack

• Backend: Kubernetes, C#, .NET
• Frontend: React, JavaScript
• Infrastructure: Azure, Cosmos DB, modern CI/CD pipelines
• Legacy: Service Fabric (during transition only)

Why This Role Stands Out

• Ownership of one of the company's most strategic technical initiatives
• Real autonomy and influence over engineering and product direction
• A growing team with clear leadership responsibility
• Defined progression toward a CTO-level role
• Well‑funded, scaling business with strong momentum
• Hybrid working: 2-3 days per week in a London office
• Competitive salary: £90,000-£110,000 + strong benefits
