▸about Luno — company background

About us:

Luno is the crypto investment app you can rely on, enabling you to buy, store and explore crypto securely. We’re committed to putting the power of cryptocurrency in everyone's hands sensibly and responsibly.

Since 2013, we’ve helped millions of people around the world invest safely in crypto. We do this by cutting through the hype and supporting customers at every step of the way. All products and cryptocurrencies on our platform must first meet stringent legal, risk and technical security standards. We don’t do memecoins.

Transparency is key for us. Luno stores all crypto on a 1:1 basis and we have rigorous processes in place so you can be confident your investment is secure. We’re available in more than 40 countries around the world and we work closely with respective regulators in all of these markets to be fully compliant, as we believe this is the best way to help everyone, everywhere, invest safely.

About the team:

You'll join Luno's Architecture team, a small group of architects who each own the architecture across Luno's business portfolios, alongside specialists in data and blockchain architecture. It's a close-knit community: architects review each other's work, share standards and patterns, and keep Luno's platform coherent as a whole.

You'll be embedded in the Payments & OTC portfolio, the teams that move money in and out of Luno: fiat payment and banking integrations across more than 40 countries, payment orchestration, settlement infrastructure, and the OTC desk that serves our largest customers. The portfolio is backend-heavy and integration-rich, spanning banks, payment providers and partner platforms, but its products surface directly in Luno's consumer and institutional web and mobile apps, so the architecture runs the full stack, all in a regulated environment.

The role in a nutshell:

You own the system architecture of the portfolio. You work as a standing peer alongside its engineering and product leadership, accountable for architectural integrity across its systems: "is it designed right, and does it fit Luno?"

This is not a coding role; its value lies in altitude and breadth, holding the architectural view across many teams and systems at once. You work through design artefacts, review and influence rather than mandate. You'll still build the occasional proof of concept, and you stay close enough to the codebase to be credible across the stack, but delivery belongs to the teams.

Your mission will be:

Own the architectural view of the portfolio: a clear, current map of its systems, contracts and domain models that teams actually use

Author high-level designs for new capabilities, and review and sign off the technical designs teams produce, guiding through questions and evidence rather than verdicts
