Sterlings are currently working with a leading UK Financial Services organisation that is investing heavily in modernising its technology estate, and we’re looking for a Principal-level engineer/ technical leader to play a key role in that journey.
This is a genuinely hands‑on technical position, combining Python development, Azure, API integration, cloud‑native architecture and technical leadership. You’ll be working on complex, high-profile initiatives and helping shape how modern integration solutions are designed and delivered.
This would suit someone who is still technically hands‑on, but is looking for the opportunity to operate at a Principal/Technical Lead level and have genuine influence over engineering and architecture decisions.
This role is 2/3 days in the London office.
