Posted on Aug 31, 2025
We are looking for a thoughtful and experienced Senior Software Engineer to contribute to the design and development of resilient, scalable backend systems that power mission-critical enterprise applications. You’ll play a key role in shaping the architecture and delivery processes behind a modern, microservices ecosystem.
This role is ideal for someone who thrives at the intersection of technical excellence and product impact; someone who doesn’t just ship code, but designs systems with long-term clarity, operational safety, and customer outcomes in mind. You’ll be responsible for applying architectural principles such as domain-driven design, enabling outageless deployments, and integrating practices like feature flagging and change isolation to support high-velocity, low-risk software delivery.
You’ll work closely with cross-functional partners across engineering, product, and DevOps to ensure our services are well-structured, observable, and production-ready from day one. While the focus is backend, any experience with frontend technologies is a bonus; especially when collaborating on full-stack solutions.
