SDE 4 - Backend

About the Role

We are looking for a seasoned backend engineer who can architect, build, and scale mission-critical systems powering the infrastructure platform. You should be comfortable owning complex distributed systems end-to-end, driving technical strategy, and raising the engineering bar while working in a fast-paced, product-focused environment.

What You'll Do

• Design and build highly scalable, low-latency backend services and APIs powering core products.
• Lead architecture for major product areas - solving hard distributed systems problems around routing, reliability, observability, performance, and data scale.
• Own system design, implementation, testing, and deployment with strong attention to reliability and correctness.
• Work closely with product, infra, and AI platform teams to deliver features with high velocity and high quality.
• Mentor engineers, influence best practices, and shape long-term technical vision.
• Drive performance optimization, cost efficiency, and operational excellence across backend systems.

What We're Looking For

• 7+ years of backend engineering experience, including building agents at scale.
• Strong proficiency in Node.js, Python, or similar languages, with experience designing and operating microservices architectures.
• Expertise in both SQL and NoSQL data stores (e.g., PostgreSQL, MySQL, Redis, DynamoDB, Cassandra).
• Strong understanding of LLMOps, agentic systems, and API platforms.
• Solid experience with AWS and/or GCP, container orchestration, and modern infrastructure tooling.
• Proven experience designing and operating high-throughput, highly available systems.
• High ownership, sound judgment, and the ability to thrive in a fast-paced environment.
• Experience in a startup or product-centric environment is a strong plus.
