## Job description

📈 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). Learn more about us on our [website](https://www.tem.energy/).

🎯 The Role We're hiring a Staff Backend Software Engineer, Pricing. You'll build and manage the Pricing API behind RED, tem's modern utility product - its performance, and its reliability. 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 senior role in our Pricing squad. The focus is backend and data-heavy, with a quant-y flavour, and correctness is critical. You'll shape how our new Pricing API is built, untangle pricing from the systems around it, and make sure that when we can't price something, we can always explain why. In your first 12 months, you might:

- See our new Pricing API built from first design through to being ready for third-party access.
- Lead the move of pricing logic into one service with a clean boundary, deciding when it is proven stable enough to cut over.
- Design the detection, alerting and explainability that catch bad or slow prices before they ever reach a customer.
- Help make pricing measurably faster for every customer quote.
- Raise the engineering bar across the squad through design reviews, standards and agent-driven workflows.

🛠️ Responsibilities

- Build & iteration of the Pricing API, so it is fast, correct and ready to be opened up to third parties.
- Support with untangling: run the extraction of pricing logic into its own service as a programme, agreeing clean boundaries with neighbouring teams.
- Own reliability: design the systems that detect pricing errors, stop bad quotes going out and explain every price we can't give.
- Raise the bar: lift the standard of everyone working on pricing through design reviews, engineering standards, pairing and multi-agent workflows.
- Close the loop: be the go-to engineer when live pricing incidents escalate, and turn what you learn into structural fixes on the roadmap.

✅ Requirements Must-Haves

- Deep production backend Python: you have designed and owned APIs at scale, and been the person others escalate to when they broke.
- You have led a significant decoupling or migration of a live system without breaking what depended on it.
- Strong FastAPI and SQL, and experience in data and analytics-heavy systems where the correctness of numbers costs money.
- You set technical direction across teams you don't manage, and can negotiate service boundaries with neighbouring teams.
- You are agent-native: you don't just use Claude or similar daily, you design multi-agent workflows that raise a whole team's throughput.
- Product engineering judgement: you know who reads a price and why, and you trade off speed, accuracy and explainability deliberately.

Desirable

- Domain knowledge from energy pricing, fintech or neo-utilities.
- Experience building APIs consumed by external third parties.
- AWS and serverless patterns (Lambda, event-driven services, Postgres on RDS).
- Polars, or a track record of making numerical code fast.

🎁 Benefits & Perks

- 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

- Intro call with Talent Partner, Jack, 30 minutes.
- Behavioural interview, 60 minutes.
- Technical interview with members from the team, 75 minutes including a practical exercise.
- Bar Raiser interview with leadership stakeholders, 45 minutes.

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.

## About tem

## Company Overview
- **One-liner**: tem is building an AI-native transaction infrastructure for energy markets, operating a modern utility (RED) that delivers cheaper, transparent electricity to businesses.
- **Entity Type**: Private (Series B)
- **Headquarters**: London, United Kingdom
- **Founded**: 2021
- **Founders**: Joe McDonald (Co-Founder & CEO), Ross Mackay (Co-Founder)

## Core Business
- **Primary industry**: Energy Technology / Energy Trading & Utility
- **Target customers**: B2B – primarily small-to-medium businesses and renewable generators; expanding to enterprise customers.
- **Mission**: “Universal access to the lowest-cost electricity” by reinventing how energy is bought and sold using AI.

## Products & Services
- **[RED](https://www.tem.energy/)**: A “neo-utility” experience for business customers. Provides transparent, 30% cheaper energy bills with half-hourly metering, no hidden fees, and a digital dashboard for usage and billing. Currently the only utility using tem’s infrastructure.
- **[Rosso](https://techcrunch.com/2026/02/09/tem-raises-75m-to-remake-electricity-markets-using-ai/)**: The core AI transaction engine that matches electricity generators with buyers. Uses machine learning and LLMs to predict supply/demand, automate trading, and remove intermediaries. Planned to be opened to other utilities in the future.

## Market Standing
- **Valuation**: Over $300 million (per a source familiar with the Series B deal, reported by TechCrunch, Feb 2026).
- **Key Metric**: Total funding raised – **$91.9M** (Pre-Seed, Seed, Series A, Series B).
- **Notable Investors/Partners**: Lightspeed Venture Partners (lead, Series B), Atomico (lead, Series A), AlbionVC, Allianz, Hitachi Ventures, Revent, Schroders Capital, Voyager Ventures.
- **Growth Signals**:
  - 6,000+ business sites now run on RED ([tem.energy](https://www.tem.energy/)).

  - 26 active job postings (as of mid-2025), with monthly job postings up 52.9%.
  - Plans to expand to Australia and Texas (US) using Series B funds.

## Competitive Advantages
- **AI-native infrastructure**: Replaces multiple human-driven trading desks and intermediaries with a single AI-powered transaction layer, drastically reducing costs and latency.
- **Transparency & pricing**: Customers save up to 30% on bills compared to wholesale market prices; bills are itemised with no hidden markups.
- **Marketplace dynamics**: Focus on decentralised renewable generators and small businesses creates an ideal environment for the algorithms, and the model scales to enterprise.
- **Dual business model**: RED proves the value of Rosso while generating revenue; Rosso is designed to become the AWS/Stripe of energy transactions.

## Strategic Focus
- **Near-term**: Scale RED in the UK, deepen customer base, and prove unit economics. Continue hiring across engineering, product, and growth.
- **Expansion**: Enter Australia and the US (starting with Texas) to replicate the model in deregulated markets.
- **Long-term**: Open Rosso to third-party utilities to capture all transaction flow, aiming to become the universal infrastructure for energy trading.

## Why Work Here
- **Culture**: Mission-driven team focused on solving climate and energy affordability through technology. Described as a “classic marketplace play” with a strong engineering ethos.
- **Remote-first**: Fully remote work environment (offices in UK but most employees work remotely).
- **Growth & impact**: High-growth startup with $91.9M in funding and a clear path to IPO (CEO has stated intention to go public). Employees have the opportunity to shape the future of energy markets.
- **Open roles**: 26 active positions including ML Engineering Lead, Staff Full Stack Engineer, Senior Analytics Engineer, Principal Product Designer, and more. Strong emphasis on technical talent (32% of workforce in technical roles).
- **Perks**: Not detailed, but the remote setup, equity in a fast-scaling company, and the chance to work on AI infrastructure for a critical industry are key draws.
