Description

  • Design, build, and operate high-performance gateway and routing components in Go.
  • Own technical direction for assigned subsystems by writing design documents, leading architectural reviews, and driving decisions.
  • Build and evolve infrastructure for authentication, caching, rate limiting, request queuing, and traffic shaping.
  • Collaborate with SRE, Infrastructure, and Platform teams to meet availability, scalability, and observability goals.
  • Deliver features end-to-end from design through production rollout and ongoing maintenance.
  • Stay current on relevant technologies, protocols, and industry patterns, and present findings for architectural review.

Requirements

  • 10+ years of professional software engineering experience.
  • 5+ years of hands-on backend development in Go with strong concurrency, performance profiling, and idiomatic design skills.
  • Deep understanding of Go internals, including the scheduler, garbage collector, memory model, and runtime behavior under load.
  • Strong systems programming foundation and understanding of how systems work below the application layer.
  • Deep knowledge of networking protocols and technologies, including TCP, TLS/mTLS, HTTP/1.1, HTTP/2, HTTP/3 (QUIC), WebSocket, and SSE.
  • Applied cryptography knowledge, including encryption, certificate chains of trust, key management, signing, and verification.
  • Proven experience designing and scaling distributed, highly available systems.
  • Solid understanding of large-scale web infrastructure, including load balancers, reverse proxies, application servers, databases, message brokers, caching layers, and observability stacks.
  • Experience authoring system or architecture design documents and leading technical reviews.
  • Ability to identify bottlenecks at both the code and system levels and propose pragmatic solutions.
  • Working knowledge of Kubernetes concepts and deployment patterns.
  • BS/MS in Computer Science, Engineering, or equivalent demonstrated experience.
  • Reading-level familiarity with Ruby on Rails, since the platform core is Ruby-based and integration points require navigating existing code.
  • Familiarity with AI/LLM serving infrastructure, including model proxying, token metering, and streaming protocols.
  • Experience with Docker, container orchestration, and cloud infrastructure such as AWS, Azure, or GCP.
  • Experience with Redis-based caching and pub/sub patterns.
  • Exposure to API gateway or service mesh internals such as Envoy, Kong, or custom proxies.
  • Experience integrating third-party REST/gRPC APIs at scale, including throttling, retries, circuit breaking, and batch processing.
  • Contributions to open-source projects are preferred.
  • Comfort working in a globally distributed team across multiple time zones.
  • Strong written and spoken English for design discussions, code reviews, and cross-team collaboration.
  • Full-cycle product delivery mindset from problem framing through production and maintenance.
  • Openness to experimentation and a pragmatic approach to adopting new technologies.

Benefits

  • Flexible, trust-oriented work culture with strong ownership.
  • Support for balancing productivity with self-care.
  • Vibrant and dynamic work environment.
