Principal backend engineer

Fyle is now part of Sage, a global leader in accounting and business management software. Together, we are building a global expense management solution that simplifies how businesses track and reconcile spending.

Thousands of finance teams globally use our product to streamline expense management, integrate seamlessly with leading accounting platforms, and are recognised for its clean design, usability, and speed.

Our backend runs on EKS / Kubernetes in AWS. Our microservices are written in Python / Flask, and we use PostgreSQL and RabbitMQ

We’re looking for someone with 10+ years of professional experience** building and scaling backend systems, who combines deep technical judgment with the ability to influence engineering direction across teams.

Technical Skills

· Strong command of performance engineering — skilled at defining benchmarks, measuring outcomes, and implementing optimisations to achieve and sustain high standards.

· Strong expertise in Python, PostgreSQL, Docker, Kubernetes, distributed systems, and event-driven architectures.

· Ability to develop novel solutions to complex technical problems with sound trade-off decisions.

· Writes and reviews high-quality design docs/RFCs; acts as a final PR reviewer across multiple product areas.

· Proactively learns new technologies and applies them to drive product or platform leverage.

What to Expect

· We value humility and collaboration — we’re looking for people who can work as part of a team, not in silos.

· We expect engineers to take ownership beyond just writing code — including tests, documentation, and long-term code quality.
