Job Description
This is a rare chance to join a start-up while it is still being shaped. The foundations are in place, customers are leaning in, and the direction is clear. What happens next will be defined by the people who join now.
You’ll be building a product that matters, and are doing it with urgency, care, and ambition. If you are excited by the idea of helping shape not just a platform but a company, this role will give you that responsibility from day one.
Why this role is special
You will not be handed a narrow set of tickets or asked to optimise something already finished. Instead, you will help decide what gets built, how it works, and how it feels to the people who rely on it. Your work will show up quickly, and you will see the impact of your decisions in real time.
This is a high-ownership role in every sense. You will be trusted to take problems end-to-end, to challenge ideas, and to bring your own judgement to the table. The platform is still evolving, which means your fingerprints will be all over it as it grows.
What it feels like to work here
Things move fast, but not recklessly. The team cares deeply about momentum and learning, and optimises for shipping, listening, and improving. You will work closely with founders and teammates who are hands-on, thoughtful, and invested in building something exceptional.
There is energy in the room. Decisions are made quickly. Good ideas travel far. If you thrive in environments where autonomy is real and standards are high, you will feel at home.
The impact you will have
You will help shape the core of the product and the experience customers have every day. You will influence how the platform evolves and how we turn insight into action. As the company grows, your role can grow with it, whether that means deeper technical ownership, product leadership, or helping set the culture for future hires.
This is a chance to do meaningful work, take real responsibility, and grow faster than you would in a more established organisation.
Who we are looking for
In this role, it’s less about experience with specific technologies and more about how you think and work. You might be early in your career or already experienced, but you are someone who has built on a strong academic background, to take pride in what you build, learning quickly, and enjoying turning ambiguity into progress.
You are excited by ownership, comfortable moving at pace, and motivated by seeing your work make a genuine difference.
What you get in return
You will be rewarded competitively and treated like an owner, with meaningful equity from the start. You will have space to shape your role, influence big decisions, and build something you can be proud of. Most importantly, you will be part of a team that cares deeply about doing great work and doing it together.
If you are looking for a role where your contribution truly matters, where the pace is energising, and where you can help define what comes next, apply today.
