Job description

About Amber

Amber is an entirely new way of thinking about buying, banking and selling energy where home energy technology works to put money back in customers’ pockets and accelerate the renewable energy transition. Everything we build is about making that possible and putting traditional retailers in the shade. We believe the cheapest, fastest and most rewarding way to reach 100% renewables is to automate the growing wave of home batteries and EVs. Customers get direct access to the real-time wholesale electricity price and the technology to shift energy usage to the times when cheaper renewables are available in the grid and export to the grid at times when the price they can be paid for it is highest. We are backed by leading VCs (including Square Peg Capital and Main Sequence Ventures), impact-focused investors and individuals, and most recently by Commonwealth Bank, NRMA, Gentrack and ETF Partners (UK/Europe based). We are growing rapidly and have thousands of customers who love what we are doing and a great product that will play a significant role in driving the world towards a renewable future. We’re now at a critical moment in taking the business to real scale in Europe as we disrupt a huge market for the better. You’d be a part of a rapidly growing team of over 140, with expertise across energy, technology, marketing, and operations. We’re committed to building a diverse and inclusive workplace and a great culture of people who love coming to work to build a better world.

Amber for Batteries unlocks more value for homeowners with batteries, driving down their energy bills and their payback periods. By storing energy when it’s cheap and exporting it to the grid for wholesale feed-in rates, Amber’s software is completely changing the economics of home batteries and accelerating the energy transition.

Amber for EVs is our EV smart charging solution that helps EV owners save on their charging costs by using more cheap, renewable energy - whether that’s their own excess solar energy, or renewable energy that’s abundant in the grid. In 2025, we are kicking off development of our game-changing vehicle-to-grid technology.

About the role

At Amber we believe that enabling a culture where everyone at Amber is set up to do the best work of their lives and feels connected and supported is one of the most important things we can do to ensure Amber’s long-term success. Want to help improve the environment by shifting the world’s energy usage towards renewables?

We are currently hiring for a Full Stack Software Engineer. Amber provides a great opportunity to apply your skills as an Engineer to help enable the uptake of renewable energy. Our technology optimises thousands of batteries and other devices in the customers' homes, enabling them to time their usage to consume power at times of high renewable penetration (and cheap prices), and then export power back to the grid at critical times - letting them outbid energy generators and earn potentially >£50 in an afternoon.

The Amber Electric product team develops and supports:

• Home automation integrations (to batteries, hot water systems and pool pumps, with EVs coming soon) that control electricity usage in response to pricing and renewable availability
• Mobile & Web apps for customers to monitor and manage their energy usage
• A pricing and billing engine for real time energy pricing

The tech stack is React Native mobile app, some React web frontends, and a Serverless Lambda backend on AWS. We’re using Typescript top to bottom, and Apollo GraphQL sits in the middle. We keep our data in DynamoDB, Postgres, and Snowflake, using one or the other as best suits a particular workload.

You can learn more about our tech stack at the site below. We do not include external links in the refined description.

While we’re looking for talented and driven individuals our desire is to build a champion team, not a team of champions. We’re full-stack-ish; while it’s impossible for everyone to excel across every layer of the stack we value people who can chip in wherever they’re needed. We’re committed to building a diverse and inclusive workplace from the ground up. We want engineers who are as comfortable communicating with people as they are with their code.

Qualifications and Skills

• At Amber, we want to hire self-starters who are eager to learn, and are comfortable working in a changing environment
• You have a positive mindset: equal parts curious, collaborative, and can-do
• Between 3 and 5 years of commercial development experience in either Web or Mobile environments
• Commercial experience with the specific technologies in our stack is a strong plus but not a hard requirement
• Experience with languages sharing features with Typescript is also a plus (such as JavaScript, C#, Go, or similar)
• We favour generalists who can be flexible across the stack, both frontend and backend
• Strong verbal and written communications skills in English at a proficiency of C1/C2 level at a minimum
• Additional language skills, particularly in European languages, are a bonus and may support broader team and customer engagement.

Your Responsibilities

• Write and maintain high quality program code across the stack in the areas of your specialty
• Flexibly contribute outside your specialty in other areas of the stack supporting your team when they need it
• Work collaboratively with your peers in product and across the wider company to ensure you're always shipping the right thing the right way at the right time
• Research, consult, analyse, and evaluate our system requirements
• Test, debug, diagnose, and correct errors in our tech stack according to our operational specifications
• Support the app across the whole lifecycle from idea through to production
• The role will see you working directly with external clients while collaborating across internal teams, including leadership, product, design, and engineering to deliver impactful solutions.

Benefits

• We’re committed to building a diverse and inclusive workplace and a great culture of people who love coming to work to build a better world
• Join a growing technology start-up that will shape the future of household renewable energy use
• You’d be a part of a growing team of 140 and above with expertise across energy, technology, marketing, and operations
• Flexible working hours & remote working - see "How You Work" for more info
• Competitive salary within your local market
• Share options in Amber Electric
• Employment and leave entitlements as per your local country
• An external Employee Assistance Plan for mental health support
• Annual Learning & Development budget to support your personal growth
• Annual company conference in Melbourne, Australia.

How You Work

• You will be working predominantly remotely within a high-trust environment where transparency and accountability are foundational to our engineering culture. Amber's flexible approach allows you to shape your schedule, but you will need to be available 2 or 3 days a week during our core collaboration hours of 7am - 10am London time. This overlap enables meaningful collaboration with your Australian colleagues.
• Outside these core hours, we trust you to manage your time effectively. We focus on outcomes and impact rather than hours logged, but we do expect consistent communication and reliable delivery on commitments. Regular check-ins and transparent progress updates are part of how we maintain this balance of freedom and responsibility.
• We value work-life balance and sustainable pace - we don't want team members to overwork or burn out, nor do we expect you to be available 24/7. Instead, we promote clear boundaries and open dialogue about workload and capacity.
• Our headquarters is located in Melbourne, Australia, with a second co-working office in Sydney, Australia. We're establishing a UK co-working hub that you'll visit during your first 2 weeks of onboarding and approximately every 2 months thereafter for team collaboration. These in-person sessions help strengthen relationships and reinforce our collaborative culture.
• You will be flown out to Australia post your probationary period for 2 weeks to meet with the team face-to-face & to collaborate locally with the Australian engineering team (this would be your final part of onboarding). We also have AmberCon every year, this is a big team calendar event and we will fly you to Melbourne to be there with the rest of the team.
• We will always cover flights, accommodation and other travel costs as part of our travel policies.

£45,000 - £70,000 a year

Salary range is between £45,000 and £70,000 base per annum and is quoted excluding superannuation. All full time roles at Amber include employee stock options over and above the base salary and superannuation.

This is a full-time role to be based ideally from the UK/Ireland/Germany but we are also open to considering the right candidate anywhere within Europe. We do have a co-working space in London where we work flexibly between the office and home.

If this kind of work gets you excited, we'd love to hear from you!

We know that no one ticks every single box in a job description, and that’s okay. If this role excites you and you feel you could bring value, we would love to hear from you even if your experience doesn’t line up 100% with the list above.

At Amber, we believe diverse teams create the best ideas and outcomes. We welcome people from all walks of life and especially encourage applications from underrepresented groups. We are committed to creating an environment where everyone has equal opportunity to thrive regardless of race, religion, color, national origin, gender identity, sexual orientation, age, marital status, or disability.

Our process will generally be as follows:

• A screen­ing interview with our AU based talent team
• A take-home technical challenge that should take no longer than four hours
• A follow up technical interview with two members of the engineering team members spread across AU and UK
• A cultural interview with our UK based Tech Lead/Software Engineering Consultant and a Software Engineering Manager
• A final chat with our Co-Founder and an executive leadership team member

Please note - As outlined in the How You Work section above, our designated core collaboration hours are from 7:00 AM TO 10:00 AM (BST). Accordingly, most of the initial screening meetings will be scheduled within this timeframe to align with our team's availability and ensure effective collaboration.

We promise to be respectful of your time as an applicant while trying to be as thorough as possible in finding the right fit for our team.

Only applicants with full working rights in the UK/Europe region will be considered for the role.

Shortlisted candidates will be contacted promptly. All other applicants will also be notified of the outcome as soon as possible.

No recruitment agencies please. We are already working with our preferred partners. Thank you!

Even if you don’t tick every box, passion and curiosity go a long way here. Don’t self-reject - go ahead and apply!
