[Hiring] Senior Backend Engineer, Platform & Integrations @Bjak

Role Description

We are looking for backend engineers to build the core systems behind BJAK's AI Finance Agent. This role is for engineers who can build reliable APIs, workflows and financial product infrastructure that can scale across markets, partners and millions of users.

• Build the system that connects to multiple insurance providers and requests quotes from all of them at once
• Design how those quotes get compared fairly and ranked for the customer
• Build the customer database and the secure audit trail required
• Set up cloud hosting, CI/CD pipeline, observability and security (encryption, secrets management)

Qualifications

• Strong backend development in Node.js / TypeScript (or very close equivalent, e.g. willing/able to work in it)
• Experience in relational database (PostgreSQL or similar) or non-relational database (MongoDB or similar) — not just querying, but designing the schema
• Experience integrating with third-party APIs, especially handling timeouts, retries, and partial failures gracefully
• Experience with cloud infrastructure (AWS, GCP, or Azure) and CI/CD pipelines
• Comfortable working with sensitive customer data and security best practices (encryption, access control)

Requirements

• Experience in fintech, insurtech, or another regulated industry
• Experience building a "plugin" or "adapter" style system that needs to support many different external integrations over time
• Experience with Redis or similar for session/cache management

Location

This role is remote, but candidates must be based in the UK. We are hiring specifically for this market, so applicants should already be based in the UK.

Language

English is our main working language across global teams. Strong English communication is required.

Interview Process

• Online assessment or practical task
• Technical interview
• CEO / final round

For strong candidates, we aim to complete the process and make an offer within 1 week from the start of the interview process. Candidates who complete assessments quickly will be prioritized.
