Join the team building Nemesis, our AI-native offensive security platform, and drive engineering projects end to end by directing AI coding agents.About the roleCasaba is a security consultancy whose clients include some of the world's largest technology companies. We also build a growing body of software, for our own use and for clients, much of it with AI coding agents. The largest project is Nemesis, our AI-native offensive security platform. Its agents reason about client code the way an expert does, trace how a system can be attacked, and investigate live targets to prove what they find. Our consultants run and orchestrate engagements on it.You'll drive engineering projects end to end, for the firm and for our clients: keeping them reliable as they roll out, fixing what real use uncovers, and building what our consultants and clients need next.Whatever the project, you'll work by directing AI coding agents. The agents write most of the code. You set the direction, verify what they produce and make the engineering decisions, with a high degree of autonomy. Major product decisions go to your lead.What you'll doLead fixes and features from report to release with AI coding agents, through design, implementation, testing and deployment.Verify the work independently. Review the changes, test the product hands-on, and catch the agent when it is confidently wrong.Keep Nemesis reliable, diagnosing and resolving issues from live engagements across our cloud services and the consultants' own environments.Work with our consultants to understand their methodology, and turn their needs into product capabilities.Handle deployment and operations across cloud services, containers and releases.Take on other engineering projects as priorities change, from internal tools and new platforms to software we build for clients.Keep your lead informed through concise written updates, and escalate the decisions that warrant it.What we're looking forRigor in verifying AI output. You treat plausible-looking work as unproven until you've seen it run.Substantial, recent experience delivering production work with agentic coding tools such as Claude Code, Codex or Cursor.5+ years building and operating production software, with a computer science background or equivalent experience.Range across languages and systems. You read unfamiliar code quickly and accurately, and can judge whether an agent's design is sound anywhere in a multi-language codebase spanning web and cloud services.Deep, hands-on cloud infrastructure expertise, including Azure: how services, containers, networking, identity and secrets fit together. Agents can write the configuration; you know when it's wrong. We run on Azure.Experience building production systems on LLMs: prompt and pipeline design, model selection, cost control and evaluating output quality.A strong bias to action and little need for process or meetings. You make most decisions yourself and recognize the ones that need escalating.Sound judgment where mistakes are irreversible, such as handling client data or changing production systems during live engagements.Clear, concise written communication.Disciplined handling of secrets and sensitive data. You'll work with client source code under strict confidentiality obligations.Nice to haveA background in penetration testing, vulnerability research or application security. This isn't required; you'll learn our methodology from our consultants.Experience shipping and supporting software that other engineers rely on every day.","company":"Casaba Security","rawCompany":"casaba security","city":"Denver","state":"CO","isRemote":false,"isActive":false,"createdAt":"2026-10-29T07:37:53.289Z","occupations":[{"code":"15-1252.00","title":"Software Developers","slug":"software-developers"},{"code":"15-1299.08","title":"Computer Systems Engineers/Architects","slug":"computer-systems-engineers-architects"},{"code":"15-1299.05","title":"Information Security Engineers","slug":"information-security-engineers"}],"industries":[{"code":"541511","title":"Custom Computer Programming Services","slug":"custom-computer-programming-services"},{"code":"541512","title":"Computer Systems Design Services","slug":"computer-systems-design-services"},{"code":"513210","title":"Software Publishers","slug":"software-publishers"}],"jobPosting":{"@context":"https://schema.org","@type":"JobPosting","title":"Senior Software Engineer, Agentic Development","description":"Casaba SecurityCasaba Security is a specialized cybersecurity consulting boutique trusted by tech industry giants for over two decades to test some of the most sophisticated products in the world.
