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 8+ 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.
