About the role

Senior Software Engineer designing and delivering backend platform at Instacart. Collaborating with teams to define best practices and improve performance and reliability

Responsibilities

Collaborate with platform engineers and SREs to deliver high-leverage capabilities that make building, operating, and scaling Go services simpler and safer.
Design, build, and evolve Go platform components (frameworks, libraries, service templates, and tooling) that are adopted across many product teams.
Define and socialize engineering standards for APIs, RPC/gRPC, configuration, observability, security, and resiliency to improve service quality and consistency.
Improve developer productivity through better build/test pipelines, reproducible local dev, CI/CD workflows, and automation that reduces toil.
Advance reliability and performance by enabling robust telemetry (OpenTelemetry), profiling, load testing, and capacity planning baked into the platform.
Lead migrations and modernization efforts (e.g., Go runtime upgrades, service mesh adoption, framework consolidation) with clear rollout and deprecation plans.
Collaborate with SRE to enhance runtime operations (service discovery, traffic management, canary/blue-green releases, incident response) for Go services.
Provide technical leadership, documentation, and enablement for teams adopting platform capabilities; participate in on-call rotations for platform-owned services.

5+ years of experience in backend software engineering building distributed systems or platforms.
3+ years of hands-on production experience with Go (designing, coding, testing, and operating Go services or libraries).
Proficiency with service-oriented architectures using gRPC and/or REST, including API design, versioning, and backward compatibility.
Experience operating services on a major cloud (AWS, GCP, or Azure), including containerization, deployment, and runtime configuration.
Strong foundations in reliability and performance: observability (metrics, logs, traces), profiling, benchmarking, and incident/on-call experience.
Track record of owning platform components (frameworks, SDKs, or shared libraries) used by multiple teams, including documentation and rollout.
Proficiency with CI/CD and build systems (e.g., Go modules, build caching, automated testing) to improve developer productivity and release quality.
Working knowledge of service security best practices (authN/Z, secrets management, transport security) and resilient patterns (timeouts, retries, circuit breaking).
Bachelor’s degree in Computer Science or related field, or equivalent practical experience.
