The posting

📈 Who We Are:

We are rebuilding the energy transaction, making it transparent and fair.

We're rebuilding how energy is bought and sold. That means cutting out middlemen, connecting businesses directly with renewable generators, and ensuring every transaction is traceable and transparent.

We're a 160+ person team - operators, data scientists, engineers, customer champions and energy experts - backed by top-tier investors including Lightspeed Venture Partners, Hitachi Ventures, Allianz, AlbionVC and Atomico. We closed a $75M Series B round in early 2026, taking our total funding to $94M, and we now power energy for over 4,000 UK businesses across 8,500+ sites, with over £75m in value returned to businesses and generators so far.

We're a technology company solving the energy industry, not an energy company. Some people call us a neo-utility, the neo-bank idea, applied to energy.

The industry is noticing. We were crowned Europe's Most Exciting Tech Company at the GP Bullhound Allstars awards https://www.gpbullhound.com/articles/allstars-awards-2026-winners-announced/, came in at #6 on LinkedIn's Top Startups 2026 https://www.linkedin.com/pulse/linkedin-top-startups-2026-20-uk-companies-rise-linkedin-news-uk-xoffc in the UK, #7 on the Scaling Europe 50 https://scalingeurope.co.uk/ of Europe's fastest-growing companies, and #14 on Sifted's AI 100 https://lnkd.in/p/ehxWgJyc.

🎯 THE ROLE

We're hiring a Senior Backend Engineer, Pricing.

You'll join the Pricing squad, the team behind the pricing engine at the heart of RED, tem's modern utility product. The systems you build price real energy contracts for businesses buying electricity and renewable generators selling it, so correctness shows up as money and speed shows up as trust.

This is a backend, data-heavy engineering role with a quant-y flavour. You'll help build our new Pricing API, make prices fast, accurate and understandable, and make sure that when we can't price something, we can always explain why.

In your first 12 months, you might:

- Design and ship core slices of our new Pricing API, taking them from first design through to production.

- Consolidate pricing logic into one service with a clean boundary, keeping pricing behaviour stable throughout the move.

- Build the detection and alerting that catches bad or slow prices before they ever reach a customer.

- Give our commercial team self-serve answers to "why can't we price this?".

- Make pricing measurably faster for every customer quote.

🛠️ RESPONSIBILITIES

- Build with impact: design and ship components of the Pricing API that price real energy contracts, owning work from design through to production.

- Make it fast: help bring the time to a first customer price down dramatically, without sacrificing accuracy.

- Own reliability: build the error handling, observability and alerting that make pricing fail loudly and explainably, never silently.

- Sharpen the boundaries: extract and consolidate pricing logic so the pricing engine owns its own behaviour end-to-end.

- Close the loop: take your turn handling live pricing questions and incidents, and turn what you learn into structural fixes.

✅ REQUIREMENTS

Must-Haves

- Production backend Python: you have shipped and run an API in production and been on the hook when it broke.

- Comfortable with FastAPI and SQL, and with data- and analytics-heavy systems where the correctness of numbers matters.

- Product engineering nous: you ask what the price is for and who reads it, not just how to compute it.

- You build with agents: Claude or similar is part of your daily workflow for writing, testing and reviewing code.

- You can own a project end to end - scoping, delivery, quality - with a tech lead as a sounding board rather than a supervisor.

Desirable

- Domain knowledge from fintech, energy pricing or neo-utilities, or ad-tech.

- Experience working inside or alongside machine learning teams.

- AWS and serverless patterns (Lambda, event-driven services, Postgres on RDS).

- Polars, or a taste for making numerical code fast.

🎁 BENEFITS & PERKS

- Competitive salary - our current band for this role is [salary band] or equivalent in local currency.

- Stock options so everyone has ownership in our mission.

- 25 days holiday plus public holidays. Swap public holidays for the ones that matter most to you, and enjoy your birthday off.

- Remote first and flexible working, with clear core hours and no internal meetings on Friday afternoons.

- Up to GBP1,200 or EUR1,400 per year for your remote setup.

- Up to GBP150 or EUR170 per month for wellbeing.

🤝 INTERVIEW PROCESS

- First call with Jack on our Talent Team (30m)

- Behaviour Interview with the Hiring Manager (60 mins)

- Technical Interview with the Team (75 mins). You'll meet with Engineers, discuss backend engineering for pricing systems, including a practical whiteboard exercise

- Bar Raiser Interview with Senior stakeholder (45m)

We welcome applications from people of all backgrounds, experiences, and identities, including those that are traditionally underrepresented in the tech and energy sectors. If you’re excited about this role but not sure you meet every requirement, we’d still love to hear from you. Your unique perspective could be exactly what we’re looking for.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
