Senior Software Engineer - Dev Accelerator

Abnormal Security is focused on building tools and infrastructure for developers, and they are seeking a Senior Software Engineer for their Dev Accelerator team. The role involves designing and evolving the internal developer platform, owning high-leverage projects across CLI tooling, CI/CD, shared libraries, and test infrastructure, while collaborating with various teams to enhance developer experience.

Responsibilities:

• 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)

Requirements:

• 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)
• Protobuf/gRPC: Schema design and evolution
• Cross-language client/server generation and integration
• Bazel in a large monorepo: BUILD rules and dependency management
• Working with code generation for APIs and clients
• Docker image builds
• Kubernetes concepts (Helm-style values, service deployments, readiness/liveness/health checks)
• Experience with a meaningful subset of AWS: object storage, relational databases (e.g., Postgres), key–value/document stores, search, streaming/ingest services, Kafka, Redis, IAM
• Modern CI systems (e.g., Git-based CI/CD platforms): Authoring non-trivial pipelines (matrix builds, reusable workflows, secrets/permissions)
• Infrastructure-as-Code mindset: Comfortable working with service manifests (YAML), Terraform/Terragrunt-like patterns, or internal equivalents
• Hands-on experience configuring and tuning linting and typing tools (e.g., pylint, ruff, mypy, golangci-lint)
• Experience writing or extending custom lint rules
• Monorepo experience: Worked in a large, shared codebase with complex dependency graphs and shared frameworks
• Familiar with dependency graph analysis and strategies to keep builds/tests fast
• Developer experience (DX) tooling: Built or maintained CLI tools, scaffolding systems, or internal frameworks used by other engineers
• Thoughtful about ergonomics, documentation, and guardrails
• Exposure to canary analysis / progressive rollout systems (e.g., Prometheus/PromQL, Grafana, automated deployment checks)
• Experience with test data management, integration/E2E test infrastructure, or bad-test detection
• Experience with Kafka (topic design, producers/consumers, observability, error handling)
• Experience or strong interest in using LLMs to improve developer workflows (e.g., failure summarization, smart code generation, AI-native CLIs)
