Creative Brand Designer

Who We Are: We are rebuilding the energy transaction, making it transparent and fair. Our goal is to put power back where it belongs, in the hands of customers and to take on one of the most critical problems of our century, access to low cost electricity. tem exists to fix a broken global energy market that’s long favoured legacy operators, intermediaries, and opaque pricing. Today’s electricity system was not designed for rapid decarbonisation, AI-driven efficiency or fair access for the actual users - businesses and generators. We’ve built the first AI native transaction infrastructure to reinvent how electricity is bought, sold and priced. Our technology is designed to cut out the inefficient fees, automate complex market flows, and bring transparency and fairness to energy transactions at scale.

In late 2025, after extraordinary growth, we closed a $75 million Series B - led by Lightspeed Venture Partners with participation from Albion, Atomico, Allianz, Hitachi Ventures, Schroders Capital and others - positioning us for global expansion, deeper product innovation and category leadership. We’re scaling internationally and building toward a future where AI-driven infrastructure is foundational to electricity markets worldwide. Since launch, our modern utility product, known as RED, has already facilitated thousands of business customers and billions in energy transaction value, proving that modern software and AI can transform an industry built on legacy systems. At tem, we’re not just building another energy company, we’re rearchitecting market infrastructure so that transparency, efficiency and sustainability become the default, not the exception.

The Role: We're hiring a Creative Brand Designer. This is a hands-on production role for someone with strong fundamentals who wants to grow fast inside a small, ambitious creative team. You'll learn how tem builds a generational brand system, and you'll contribute real output every week. The job is to ship reliably and well, freeing senior designers to lead the work rather than make all of it.

You will:

• Produce polished brand and campaign assets across web, lifecycle, social, decks and one-pagers.
• Adapt key visuals into channel-ready formats and keep files clean, organised and easy to reuse.
• Maintain and extend the design system templates and components so good becomes the default.
• Build AI workflows into your own production process to ship more, faster, without losing the bar.

You will report into the Head of Brand, with day-to-day support from Senior and Lead designers.

Responsibilities:

• Ship the work: Execute high-quality brand and campaign assets across all marketing surfaces, following (and strengthening) the design system.
• Adapt key visuals into channel-ready formats: web, lifecycle, social, decks, one-pagers.
• Prep files for handoff, manage versioning, and ensure accuracy and consistency end-to-end.
• Strengthen the system: Maintain and expand templates and components so the team's baseline lifts over time.
• Keep files clean, organised and reusable by others - leave the system better than you found it.
• Spot gaps in the system and propose fixes rather than working around them.
• Move fast with AI: Use AI tools intentionally to accelerate your own production work.
• Build repeatable workflows (prompt patterns, asset pipelines, automations) that compound across projects.
• Evaluate AI output critically - speed is only useful if the bar holds.
• Collaborate and grow: Work closely with Content, PMM and Growth partners to turn briefs into clean output.
• Take feedback well, iterate quickly, ship to a high standard with increasing independence.
• Bring proposed options to reviews, not just open questions.

Requirements:

Must haves:

• A portfolio showing strong fundamentals - typography, layout, hierarchy - and clear good taste.
• Experience producing design across multiple formats (digital and/or brand) in a fast-moving environment.
• Confident in Figma and comfortable collaborating in shared files.
• Already using AI intentionally in your own design and production workflow - not just experimenting.
• Organised and reliable: tracks your own work, flags blockers proactively, doesn't need chasing.
• Willingness to move fast, take feedback, and iterate without ego.

Bonus points:

• Familiarity with web design constraints and responsive thinking.
• Experience building or maintaining a design system rather than just consuming one.
• Motion or interaction design fundamentals.

Benefits & Perks:

• Salary aligned to internal benchmarks and reviewed twice a year.
• 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.
• Home working and wellbeing budgets: Up to £1,200 or €1,200 per year for your remote setup. Up to £150 or €150 per month for wellbeing.

Interview Process: We move fast. Most processes take 2 to 3 weeks from first chat to offer. If you need us to adapt anything, let us know. Intro call with Talent, 30 minutes. Hiring Manager interview, 60 minutes. Portfolio and craft interview with the Brand team, 60 to 90 minutes, including a practical exercise. Culture Add 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.
