- The engineering culture emphasizes technical excellence, strong ownership, and close collaboration across globally distributed, remote-first teams.
About the Role:
We are looking for a Senior Golang Engineer to join our Gateways team and work on the core Model Context Protocol (MCP) infrastructure. Responsibilities may include:
- Building and maintaining high-performance gateway and routing components for the MCP multi-tenant infrastructure.
- Contributing to MCP specification development and pushing ideas into the broader ecosystem.
- Developing server-side infrastructure for logging, monitoring, and observability.
- Owning features end-to-end — from design through production and ongoing maintenance.
- Debugging complex production issues at the network, OS, or infrastructure level.
- Writing Kubernetes manifests and managing deployments for critical workloads.
- Evaluating and proposing architectural improvements andcontributing to technical reviews.
- Collaborating closely with the Infrastructure teams to ensure high availability and scalability.
- Thriving within a distributed, multi-cultural team with async-first communication.
Core Tech Stack: Golang, Ruby on Rails, Kubernetes, Kafka, AWS, PostgreSQL, Redis, ClickHouse, Terraform, Prometheus.
What You Have:
- 8+ years of industry experience in software engineering.
- Expert-level Go proficiency (4+ years): deep understanding of how the language works under the hood — not frameworks, but goroutines, memory, etc.
- Strong command of low-level networking specifics: TCP handshake mechanics, TLS/mTLS negotiation, understanding of mTLS operating modes and trade-offs, load balancer types (L4 vs. L7), and when to use each.
- Solid Kubernetes knowledge ( network policies, writing production-grade manifests; bootstrapping clusters from scratch is a big plus).
- Hands-on experience with major cloud providers ( ideally, AWS — hands-on debugging in production, undocumented behavior, and edge cases).
- Familiarity with Kafka at a conceptual level ( topics, partitions, rebalancing).
- Experience with observability and monitoring ( Prometheus, alerting).
- Experience with building and scaling distributed, highly available systems.
- Autonomous and proactive mindset— comfortable owning a full stack slice end-to-end, surfacing problems without waiting to be asked.
- Excellent analytical and problem-solving skills— can explain the reasoning behind technical/
