Backend Engineer | Python, AWS, Postgres | Profitable Market Intelligence SaaS

• Salary: £45,000 - £60,000, reviewed every Q1
• Location: hybrid, 3 days a week in central London
• Degree: computer science, maths or a science subject from a Russell Group university
• UK right to work required

I'm working with a self-funded market intelligence business in London who are hiring a Backend Engineer to build the APIs their biggest clients plug straight into. Their SaaS platform spots market-moving events early, so clients can act before the news is widely reported.
It's a small, profitable team. You'll work in Python, Postgres and AWS, sitting next to the co-founder and a senior full-stack engineer three days a week, with the room and the backing to lead how the whole business uses AI.
What They're Looking For (Non-Negotiables)

• Python: six months to three years of commercial backend experience
• APIs: building and consuming them
• SQL and relational data modelling
• AI tooling: Claude, Copilot, Cursor or similar in your daily work
• You'll bring ideas on tooling and process, and you'll push for them
• You're keen to learn and open to feedback from senior engineers

What You'll Work With

• PostgreSQL
• Amazon Web Services (AWS)
• Claude API
• Data pipelines: fetching external data and building tables
• React, alongside the full-stack engineers

Nice to Haves

• Trading, pricing or market data experience
• Financial data feeds
• LLM features in production, beyond coding assistants

Why Join / Projects
Your first project is connecting the platform directly to clients through APIs, starting with their trading clients. The client list runs from financial institutions to well-known consumer brands.

• You'll own AI for the business, finding uses well beyond engineering and championing them across the company.
• You'll have the co-founder's ear, with the freedom to recommend and make changes to tooling and direction.
• You'll learn from two senior full-stack engineers, one alongside you in the office.
• The business is self-funded and profitable, so you're building on solid ground.

Employee Benefits

• Salary review every Q1
• 25 days paid holiday
• NEST pension
• No overtime culture

It's a two-stage interview process and they're moving quickly, so apply and I'll give you a call.
