About Esenda

Esenda powers over £1.5bn of inbound and outbound payments annually, in the education space - from tuition and catering fees to supplier payments and payroll. We’re a revenue-generating startup with strong product-market fit, and we’re growing fast. Join us now and you’ll work on impactful features that directly shape our platform and make a real difference to our customers.

What you’ll do

  • Design, build, and ship reliable backend services and APIs in Python (Flask) that power core product functionality.
  • Own features end-to-end: data modelling (Postgres), API design, testing, production rollout and ongoing improvements.
  • Help uphold strong engineering standards through thoughtful code reviews, testing discipline, clean architecture, and pragmatic decision-making.
  • Improve service reliability and operability: monitoring, alerting, logging, runbooks, and reducing on-call toil over time.
  • Work closely with the technical team to scope product ideas, focused on delivering customer-facing outcomes (not just “tickets”).
  • Contribute to delivery practices: CI/CD improvements, incremental shipping, and maintaining a high-quality codebase.
  • You’ll join an on-call rotation (1 week in 4) compensation: paid as an extra ÂŁ300 per on-call week.

What we’re looking for

  • 5+ years experience building and operating production backend systems.
  • Strong experience with Python, and hands-on use of Flask (or similar frameworks).
  • Solid understanding of Postgres (schemas, migrations, query performance, transactions).
  • Experience designing and maintaining APIs (REST; event-driven experience is a plus).
  • Comfortable shipping in cloud environments—ideally AWS—and working with modern CI/CD pipelines.
  • A strong quality mindset: you care about maintainability, security, reliability, and clear documentation.

Bonus points for

  • Payments/fintech knowledge (reconciliation, idempotency, auditability, ledger concepts).
  • Experience with distributed systems patterns (queues, background jobs, retries, rate limiting).
  • Security experience (threat modelling, OWASP-style concerns, secure API design).
  • Familiarity with Terraform.

Why join us?

  • ÂŁ60k salary + equity
  • 40 days holiday (incl. bank holidays)
  • Pension scheme (3% employer contribution)
  • Fully remote, UK-based, with 3 in-person meetups per year
  • A transparent, collaborative, and supportive culture

Our stack (today)

  • Backend: Python, Flask
  • Data: Postgres
  • Cloud: AWS
  • Edge: Cloudflare
  • Infrastructure as Code: Terraform
  • Delivery: CI/CD, automated testing, observability tooling

How we work

  • Pragmatic, high-ownership teams with a bias to shipping
  • Clear communication, strong collaboration, and continuous improvement
  • Code reviews and sensible standards that keep quality high without slowing delivery

Interview process

  • 30-min intro call (role fit, values, ways of working)
  • Practical exercise (small take-home or pairing session)
  • Technical interview (backend fundamentals, API design, production thinking)
  • Team chat + Q&A
