Senior Software Engineer Job at London Full Time

Job Description

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
• Clear, proactive communication — especially when things are uncertain

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.

BENEFITS

• 25 days annual leave plus public holidays
• MacBook and any additional tech or software you need
• Flexible working arrangements
• Private Health, Dental, and Vision Insurance through Aviva
• Income Protection Insurance
• Extended mental health cover and Employee Assistance Programme
• Compassionate leave policy
• Private pension contributions (Royal London)
• Monthly company social events
• Regular in-person hackathons
