Senior Software Engineer - Dev Accelerator

About the team

The Dev Accelerator team builds and operates our internal developer platform: the tools, libraries, and infrastructure that let 100+ engineers design, build, test, and ship products quickly and safely.

We own:

• Developer CLI tooling – a “Prompt-to-Product” style CLI that scaffolds services end-to-end, environment/credentials tooling, and a wide range of internal developer scripts.
• Monorepo build, lint, and CI infrastructure, including our core backend CI workflow, Bazel integration, and a custom linting framework and rule set used across the codebase.
• Go ecosystem stewardship for a large suite of shared libraries and applications under our main Go module.
• Python shared libraries & frameworks for core business logic, gRPC helpers, utilities, and standardized component libraries (datastores, messaging, web, etc.).
• Engineering effectiveness & test infrastructure, including automated canary analysis, test data and coverage tooling, bad test dashboards, dependency analysis, and “broken main” automation.

Our goal is to make the easy path the right path for product teams and AI agents building on the platform.

About the role

As a Senior Software Engineer, Dev Accelerator, you will:

• Design and evolve the internal developer platform that underpins virtually all backend development.
• Own high-leverage projects across CLI tooling, CI/CD, shared libraries, and test infrastructure.
• Work across Python, Go, Bazel, Kubernetes, AWS, and CI systems to make our Golden Path fast, reliable, and intuitive.
• Shape abstractions and workflows that are AI-native, consumable by both humans and AI agents.

You’ll operate as a senior IC, leading multi-quarter initiatives and collaborating with product teams, infrastructure, SRE, and Security.

What you’ll do

• Build and evolve developer CLI tooling
• Extend our primary developer CLI to scaffold new component types and services end-to-end (service manifests, container/build configs, deployment charts, build files, API definitions, starter code, alerts, runbooks).
• Improve environment and credentials tooling to make local development setup fast and reliable.
• Own core CI/CD and linting infrastructure
• Design and maintain the backend CI workflow used by backend services.
• Evolve linting, formatting, and typing tools to enforce architectural and code-quality guardrails across the monorepo.
• Debug and fix CI issues that block engineers, and proactively reduce flakiness and runtime.
• Steward shared Go and Python ecosystems
• Own key shared Go libraries (auth, caching, clients, configuration, cryptography, logging, metrics, domain/realm, server, etc.) and their usage across many applications.
• Maintain and evolve Python shared libraries and frameworks in our core libraries, gRPC helpers, utilities, and standardized components.
• Strengthen test and release safety
• Extend automated canary analysis with new metric types, backtesting, and safer defaults.
• Build and improve test automation tooling, bad-test detection dashboards, and dependency-analysis utilities to keep main green and tests reliable.
• Contribute to automation that classifies CI failures and summarizes them for engineers (including LLM-assisted workflows).
• Drive platform-level design and abstractions
• Design abstractions that balance simplicity for product engineers with enough power for advanced use cases.
• Collaborate with PM/TPM, infrastructure, and product teams to scope and deliver multi-team initiatives (e.g., prompt-to-product workflows, typing and linting initiatives, test automation).

Required technical skills

Languages & frameworks

• Strong experience with Python 3.x:
• CLI development (e.g., Click or similar).
• YAML/Jinja2-style templating.
• Modern type hints and typing discipline (e.g., typing, dataclasses / attrs, Pydantic-style patterns).
• Testing with pytest or similar.
• Solid experience with Go:
• Shared library and service development (gRPC/HTTP).
• CLI patterns (e.g., Cobra/Viper or equivalents).
• Testing with Go testing frameworks (e.g., Ginkgo/Gomega or the standard library).

Protocols & APIs

• Protobuf/gRPC:
