Software Engineer, Backend (Go)

Must Have

• The "I'll figure it out" instinct — you research, experiment, and read source code before asking to be unblocked, and you ask a well-formed question when you are.
• Something you built and can walk us through in detail: what it does, why you designed it that way, and what you would change now.
• Willingness to be reviewed rigorously and to treat feedback as the fastest way to get better.
• Testing instinct — you can explain how you know your own code works.
• Authorization to work in the United States.
• Nice to Have

• Python or TypeScript for E2E suites and client SDKs.
• Security engineering: threat modeling, secret management, dependency and container scanning.
• CNCF open-source contributions.

• Bachelor's degree in Computer Science, Software Engineering, or a related field — or equivalent demonstrated ability.
• Solid CS fundamentals: data structures, algorithms, concurrency, networking, and how HTTP and databases actually work.
• 4-5 years of professional software engineering, including 2-3+ years building production backend services in Go (4+ years of Go preferred).
• Strong Go fundamentals: concurrency, context propagation, error wrapping, stdlib HTTP routing (Go 1.22+).
• Experience building and shipping REST APIs, and a working understanding of versioning and backward compatibility.
• Solid relational database skills — schema design, migrations, transactions, and query tuning.
• Testing discipline: unit and integration tests are part of your definition of done, alongside code review and CI/CD (GitHub Actions or equivalent).
• Clear written English for design docs, review comments, and asynchronous collaboration across global time zones.
• Durable Workflow Execution: Temporal orchestrations.
• Cloud-Native & Kubernetes Ecosystem: Container orchestration using Kubernetes, Cluster API, custom controllers and operators, Docker runtime, and deployment packaging through Helm charts.
• Identity Federation & Ingress Gateway: Keycloak architecture (realms, client configurations, federated providers, auth token lifecycles) alongside Envoy or comparable edge proxies (traffic management, filter chains, rate limiting policies).
• Persistence & Event Infrastructure: Relational data persistence in PostgreSQL with database schema migration workflows, coupled with distributed streaming platforms like Apache Kafka or NATS JetStream messaging.
