Electricity runs behind everything we build.
Businesses rely on it. Communities rely on it. Entire industries depend on it. Yet the systems behind energy haven’t kept pace with the world around them. Too complex. Too opaque. Too slow to change.
We think that should change.
At tem, we’re rebuilding how energy is bought and sold — creating technology designed to make electricity fairer, more transparent and built for what comes next. Not another energy company. A better system behind energy.
And we’re looking for people who want to help build it.

Roles on offer
26 Jun
Assessment day, London
How it works
Three stages, no surprises.
No long waits. No endless interview rounds. No guessing where you stand.
Apply. Attend the day. Find out.
Stage 01
Apply
Upload your CV, LinkedIn and show us something you've built. Then complete a short written assessment designed to be difficult to fake and easy to do well if you're thoughtful.
Stage 02
Come to the day
We invite around 15 people to London for an in-person assessment day. You are paid for your time. If you are travelling from outside London, we will cover domestic travel costs up to £150. The day includes a guest speaker, a hands-on AI challenge, and a structured assessment. We want the experience itself to be worth your time.
Stage 03
Get Hired
We identify the strongest candidates across the day and invite them for a brief conversation before close. Offers are issued the following morning. You will indicate the role you are applying for, and If we think you'd thrive elsewhere at tem, we'll tell you. Everyone receives a clear response.
What to expect
The day, laid out.
Here's exactly what to expect.
09:00
Arrival, coffee, introductions.
Arrive, get set up, and meet the team. We will walk through the structure of the day, confirm your access to the tools and answer any questions before we begin.
09:30
Talk: a guest worth listening to.
We've got someone coming in to talk about building in a hard industry. Not a corporate keynote. More like a 30-minute conversation you'll actually remember. This is part of the day regardless of what else happens.
10:15
The challenge begins.
You'll be given a brief and a set of tools. Your job is to find the problem worth solving, then show us how you'd solve it. We're not looking for a polished deck. We're looking for how you think when you're under a bit of pressure.
13:00
Lunch.
Proper food. Time to breathe, talk to people, and not think about the challenge for an hour.
14:00
Presentations and challenge wrap-up.
You present back what you found and how you'd approach it. Short and sharp. This isn't a formal pitch. It's a conversation. We'll ask questions. Push back where it makes sense. See how you handle it.
15:30
Conversations.
We pull aside the people we want to keep talking to. Short. 15 to 20 minutes each. We tell you what we're thinking and give you the chance to ask us anything.
17:00
Day wraps up.
Everyone gets swag and payment sorted. If you travelled from outside London, we will reimburse domestic travel up to £150. Offers go out the following morning.
The roles
Six roles. One process.
Apply and indicate which role interests you most. Growth roles at tem are genuinely hybrid, and if we think another role would be a stronger match we will let you know. Great people don't always follow expected paths.
Growth
Growth engineer
From £50k
A developer who sits in marketing. Rare and valuable. You build the tools, automations, and experiments that the rest of the team can't. If you can write code and you're curious about how businesses grow, this one's for you.
Python / JS
API
Automation
AI-Native
Marketing
Product marketing
From £50k
You understand the product deeply, you know what the customer actually cares about, and you can translate between the two in a way that drives pipeline. This is a builder role, not a coordinator role.
Positioning
Messaging
Enablement
Research
Growth
Growth and demand gen
From £50k
You think in experiments. You're comfortable with numbers and equally comfortable writing copy that converts. You care about the whole funnel, not just the top of it.
Paid / organic
Analytics
Copywriting
Testing
Lifecycle
Lifecycle
From £50k
You're obsessive about what happens after someone becomes a customer. Onboarding, retention, expansion. You use data to spot the moments that matter and you make sure we're showing up in them.
CRM
Segmentation
Retention
Community
Field and community
From £50k
You're good with people and you want to be out in the world, not behind a screen all day. You help build tem's presence in the places that matter. Events, networks, the energy industry ecosystem. You're the face of the brand in rooms we can't always be in.
Events
Partnerships
Community
Content
Content
Content producer
From £50k
You sit at the intersection of writing, design, and production and you use AI to move faster than a traditional content team would think possible. You're not precious about the tools. You care about the output: content that builds trust, earns attention, and makes tem look like a company worth working for and buying from.

Benefits and perks
What you get.
We want people to do the best work of their lives here. That means paying fairly and giving real ownership.
Pay and ownership
Salary benchmarked internally and reviewed twice a year. Stock options so everyone has real ownership in what we are building.
How we work
Remote first with flexible hours. We have clear core hours so you know when to be available, and no internal meetings on Friday afternoons. Protect your focus time.
Time off
25 days holiday plus public holidays. Swap public holidays for the ones that actually matter to you. Your birthday off, always.
Home and wellbeing
Up to £1,200 per year for your home setup. Up to £150 per month for wellbeing, however that looks for you.
Your application
Two step application
01 Application
Drop your CV, your LinkedIn, your folio or repo, and tell us why tem. Takes about five minutes. No cover letter needed.
02 Assessment
Six timed written questions. Two minutes each. This is the part we weight most heavily: it is designed to show us how you think, not what you know. You will need somewhere quiet and about 15 minutes.
WHY TEM
Learn faster.
Build earlier.
Graduate roles often promise responsibility later.
We believe responsibility creates growth.
From day one you'll work on real projects with people solving difficult problems across technology, operations, marketing, commercial and product.
You'll contribute. Collaborate. Ship work. Learn quickly.
And have the opportunity to make an impact earlier than most careers allow.
