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
