Agent guide: [/agents.md](https://www.wearedevelopers.com/agents.md). --- # Software Engineer, Agentic Systems - **Company:** STACKHAWK, INC. - **Location:** Denver, CO, United States (Remote available) - **Experience:** Expert - **Contract:** Permanent contract - **Skills:** Java (Programming Language), Application Programming Interfaces (APIs), Artificial Intelligence, Automation of Tests, Command-Line Interface, Software as a Service, Cursor (Graphical User Interface Elements), Software Debugging, Github, Gradle, Python (Programming Language), PostgreSQL, Open Source Technology, TypeScript, Rust (Programming Language), Large Language Models, Multi-Agent Systems, Software Security, Gitlab, Kotlin, Build Management, Kubernetes, Api Design, Grpc, Docker, Golang, Microservices - **Published:** September 27, 2026 - **Apply:** https://www.juju.com/job/16_9db367c01 ## About the Role * 6+ years building and shipping production SaaS software * Deep in at least one statically typed language. Python, TypeScript, Go, or Rust experience is where our agent tooling and CLI live, so that helps immediately * Our core platform is Kotlin and Java. We do not require you to have written either. If you are strong somewhere else, you will be productive in our codebase inside a month and we are fine with that math * Experience with microservices in a modern cloud environment, containers, and container orchestration * Solid API design instincts and the tooling that goes with it * Obsessive about automation and automated testing Agentic experience (this is the part we care most about) * You have built something with an agent loop, not just called an LLM API. Tool calling, multi step execution, retries, failure handling, knowing when to stop * You have written evals for non-deterministic output. You can talk about what you measured, why that metric was the right one, and what it missed * You have done real context engineering. You know that most agent failures are context failures, and you have the debugging stories to prove it * Bonus: you have built or published MCP servers, agent skills, or custom agent integrations If your agentic experience is one weekend project and a course certificate, this is not the right role yet. If it is a system you shipped, maintained, and had to debug at 11pm, we want to talk. ## Description StackHawk builds the security layer for AI-assisted engineering. Our platform finds exploitable vulnerabilities in running applications and APIs, then hands the proof and the fix path directly to the coding agent already sitting in the developer's editor. Claude Code, Cursor, Copilot, Codex. Scan, fix, verify, in a loop, without a human copying findings between tabs. That product is real and shipping. It is also early, which means the architecture decisions that matter most have not been made yet. We are looking for a senior engineer to own that loop. You will spend most of your time on agentic systems: the tool surfaces our agents call, the context they get, the loop that decides when a fix is actually verified, and the evals that tell us whether any of it got better this week. You will also work in the core platform, because the loop is only as good as the scan engine and APIs underneath it. This is not a research role. Everything you build goes to customers. The team is small. Your work will be visible in the product within days, and in customer conversations within weeks. Want to see what we mean before you apply? Our agent skills are open source at github.com/stackhawk/agent-skills. Read them. If you look at that and immediately have ideas, apply. On Denver This role is onsite in Denver. We know that narrows the pool and we are doing it on purpose. The hard part of this work is not writing the code. It is the whiteboard argument about why the loop stopped early, the shoulder tap when an eval result looks wrong, and the twenty minutes after a customer call that turns into a design change. That happens in a room with our small team. What You'll Do * Design and build the find, fix, and verify loop that powers our agentic security workflows * Build and own the tool layer coding agents use to reach our platform. Some of this exists and needs a rewrite. You will have a strong opinion about how, and the room to act on it * Extend our published agent skills, which are open source and in use today * Do the context engineering work that makes the difference between a useful agent and a plausible one. Decide what the model sees, in what shape, and at what point in the loop * Build eval harnesses for non-deterministic systems. Define what "better" means, measure it repeatably, and defend the number * Build core product features and supporting services in a microservices architecture using Kotlin, Java, Rust, gRPC, Postgres, Docker, Kubernetes, and Gradle * Design and build APIs for both our UI and our customers * Build developer-facing command line tooling * Integrate with the platforms engineers already live in: GitHub, GitLab, CI systems, IDEs, and agent runtimes * Work directly with product, security, and go to market. We are small enough that you will hear customer feedback firsthand and ship against it * Learn more about vulnerability classes than you expected to, and get very good at explaining Remote OS Command Injection at parties, AppSec depth is a strong plus, not a requirement. If you already know your vulnerability classes cold, that will accelerate everything. If you do not, we will teach you, and you will learn faster here than anywhere else. What we do require is curiosity about how software breaks and the discipline to care about correctness. An agent that reports a fix it did not verify is worse than no agent at all. How you work * Accountable. You own outcomes, not just tickets. When something you shipped breaks, you are already looking at it * Persuasive. You bring people to your position with logic and data, not volume * Self motivated. You do not need to be told what matters twice * Focused. You finish things before starting new things * Collaborative. You know security is a supporting function of a business, and you know the difference between binary security and security at scale How We'll Evaluate ## Related Videos - [Exploring the Power of gRPC-Gateway for Writing RESTful Services](https://www.wearedevelopers.com/videos/2072-exploring-the-power-of-grpc-gateway-for-writing-restful-services) - [Go with the Flow: Stop the Leaks Before Your Memory's a Waterfall!](https://www.wearedevelopers.com/videos/100073-go-with-the-flow-stop-the-leaks-before-your-memory-s-a-waterfall) - [Docker Compose: Rediscovered](https://www.wearedevelopers.com/videos/1978-docker-compose-rediscovered) - [Agentic AI: building autonomous systems for developers](https://www.wearedevelopers.com/videos/100034-agentic-ai-building-autonomous-systems-for-developers) - [Boosting OpenSearch Performance: gRPC Search in Action](https://www.wearedevelopers.com/videos/1964-boosting-opensearch-performance-grpc-search-in-action) - [Supercharge Agentic AI Apps: A DevEx-Driven Approach to Cloud-Native Scaffolding](https://www.wearedevelopers.com/videos/1604-supercharge-agentic-ai-apps-a-devex-driven-approach-to-cloud-native-scaffolding) ## Related Articles - [What is Agentic Programming and Why Should Developers Care?](https://www.wearedevelopers.com/magazine/625-what-is-agentic-programming-and-why-should-developers-care) - [A 5-Step Open-Source Setup for Agentic Engineering](https://www.wearedevelopers.com/magazine/738-a-5-step-open-source-setup-for-agentic-engineering) - [ I Gave a Video Editor More Autonomy Than a Trading Bot.
