Senior Software Engineer

Senior Software Engineer Location: UK Remote / Hybrid Salary: up to £80,000

ABOUT THE COMPANY

Financial Times' fastest-growing software company in Europe, this is an AI and automation platform — used by thousands of people, every single working day. Founded in 2020, they've grown to 90 people and were voted one of The Sunday Times' Best Places to Work. They're not slowing down.

The engineering team is small enough that your decisions matter, large enough that you're not doing it alone.

THE ROLE

This is a senior, hands-on engineering role — not a stepping stone to management, though it can be if that's where you want to go. You'll own complex technical work end-to-end, shape architecture and engineering standards, and raise the quality of the team around you.

The platform is genuinely interesting: Python backend services, Svelte and jQuery frontend, AWS infrastructure, Chrome and email extensions, CRM integrations, and OpenAI-powered automation workflows. You'll work across it.

Impact here is measured by the quality of the whole team's output, not just your own. If that sounds like a burden, this probably isn't the right role. If it sounds like the interesting part, read on.

WHAT YOU'LL BE DOING

Owning the delivery of complex features and systems, end-to-end

Breaking ambiguous product problems into scalable technical solutions

Making architectural and implementation decisions across the engineering stream

Writing maintainable, predictable, scalable code (and expecting the same from others)

Conducting code reviews that improve both the code and the engineer who wrote it

Mentoring junior engineers on implementation, design patterns, and engineering practice

Identifying and resolving systemic technical issues, not just isolated bugs

Improving deployment reliability, monitoring, and observability

Communicating trade-offs and risks clearly — to engineers and non-engineers alike

Participating in and leading production incident response where needed

WHAT THEY'RE LOOKING FOR

Essential

Strong professional experience with Python backend development

Solid understanding of APIs, distributed systems, and scalable application design

Experience working across complex, multi-surface product ecosystems

The ability to mentor and elevate engineers around you

Beneficial (not required)

Frontend experience with Svelte and/or jQuery

AWS cloud infrastructure

OpenAI APIs or LLM-powered application development

Browser or email extension development

CRM integrations

Observability and operational tooling

WHAT GOOD LOOKS LIKE HERE

Over time, senior engineers at this company become trusted owners of complex systems, lead technical initiatives involving multiple engineers, and raise standards across their stream through mentoring and technical leadership. The role can grow towards Principal Engineer, Systems Architect, or stream-level technical leadership — depending on where your strengths take you.
