About them:

They are the next-generation compliance platform for financial services, offering an agentic solution powered by real-time data for business identity.

Always-on and policy-aware, they enable financial institutions and fintechs to gain actionable insights into business verification - unlocking growth, increasing efficiency, and strengthening compliance.

They were founded by former operators and builders with deep experience in banking, payments, and lending. Today, their team spans across London and Porto, bringing together engineers, product owners, and operators from companies like Revolut, Meta, Block (Square), SumUp, American Express, Yandex, and Marshmallow. Trusted by leading regulated entities, including Wise, Tide, Mollie, Shift4, Flatpay, and myPOS, they are backed by top investors, including Lightspeed Venture Partners and MMC Ventures.

They are looking for a Senior Backend Engineer to join their team.

You will be a shaper of the design and architecture of the core platform and work closely with the founding team to deliver 10x value to our clients.

As an early-stage startup, they pride themselves on their ability to roll up their sleeves and build from scratch. You’ll ship code frequently, iterate quickly based on feedback, and still meet the stringent security, performance, and uptime requirements their clients expect.

They all love to build, scale, and grow: their leadership team has a strong track record of building products, scaling teams, and driving growth, and their ambitious engineers join us from leading tech companies and unicorns.

If you’re passionate about turning complex problems into simple, elegant solutions, this role is for you. You’ll have a meaningful opportunity to shape our engineering culture from the ground up.

What you'll do

• Design and own the core of their platform, from architecture to implementation

• Build a robust, secure, and resilient data ingestion layer capable of handling diverse and high-volume data sources

• Develop a performant scraping and parsing layer to reliably capture and structure data from the web and other external systems

• Deliver customer-facing APIs and developer-friendly documentation that enable a seamless self-service product experience

• Impact and shape the engineering culture, setting high standards for quality, ownership, and collaboration

• Continuously improve their software engineering practices and processes, driving better reliability, scalability, and developer productivity

What you bring

• 5+ years of backend engineering experience, with a track record of owning systems end-to-end in production

• 3+ years of Python (or a similar language with the willingness to work primarily in Python)

• Strong fundamentals in distributed systems: asynchronous processing, queues and pub/sub, idempotency, retries, eventual consistency, and designing for failure

• Strong experience designing customer-facing REST APIs that are clean, versioned, and pleasant for developers to integrate against

• Strong relational database modelling skills (PostgreSQL or MySQL), including indexing, query performance, and schema evolution under load

• A product engineering mindset: you care about what you're building and why, talk to users, and ship the thing that actually solves the problem rather than the most technically interesting version of it

• Comfort working in a cloud environment (GCP, AWS, or Azure) and shipping reliably with modern CI/CD , without needing to be the team's dedicated platform engineer

• Excellent communication and collaboration skills in a fast-moving environment
