AI Software Engineer

StackHawk helps software developers find and fix security vulnerabilities before they deploy code to production. Every modern software development organization has shifted from quarterly releases to daily or hourly releases, incorporating Continuous Integration and Continuous Delivery (CI/CD). In the modern world of FinTech, HealthTech, cloud analytics and AI platforms, customers are entrusting their most critical data to software providers. Periodic manual security testing by an external team is simply too risky. Because of this, modern software development organizations are extending CI/CD to encompass Continuous Application and API Security Testing. This way, security can “shift left,” meaning vulnerabilities can be detected while the developer is actively working on the code.

StackHawk leads the market in developer first API security testing. Application and API security is an exciting market, where more than 43% of global decision makers are looking to implement dynamic application security testing during software development, which represents a massive opportunity for StackHawk. StackHawk is building out a team of leaders and team members that will capitalize on market pull, and enable growth-phase scale of the business.

Are you an experienced AI engineer eager to design and ship cutting-edge AI systems? Do you want to shape the future of developer-focused security tooling? Can you tolerate ridiculous bird puns? If so, keep reading to learn about an exciting opportunity at StackHawk!

• Hands-on experience with frontier model tools such as tool calling, MCP, context management, prompt tuning, and evaluation frameworks.
• Knowledge of retrieval systems, embeddings, semantic search, and orchestration of complex AI workflows.
• Experience with NLP tasks: summarization, entity extraction, dialogue systems, or semantic understanding.
• Experience working with frontier models from OpenAI and Anthropic, including token-based inference and orchestration.

• Software Engineering Excellence
• Proficiency in Rust or similar high-performance languages (Go, C++, systems-level Python).
• Experience building production-grade services in cloud-native environments (AWS, GCP, or Azure).
• Strong background in scalability, observability, and distributed systems.

• Operational Rigor
• Experience deploying and operating AI systems in production.
• Familiarity with CI/CD pipelines, automated testing, and evaluation frameworks.
• Commitment to reliability, cost efficiency, and user trust.

• Mindset
• Quality-minded, with a deep respect for correctness.
• Comfortable working at the intersection of research and production engineering.
• Collaborative and impact-driven, with a track record of influencing technical direction.

• Background in applied research or experience contributing to open-source AI/ML projects.
• Familiarity with compliance and regulatory requirements for AI systems.
• Colorado based - our headquarters are in Denver and while we primarily work from home we have lots of fun
• We’re headquartered in Colorado and prefer to hire locally, but we welcome strong candidates from anywhere in the U.S.

• Competitive Compensation: Earn a competitive salary and get an equity stake in the company that we are building together.
• Solid Benefits: Health, dental, and vision insurance 100% paid for employees and dependents. Other benefits include life insurance, AD&D, and 401K
• Time to Recharge Encouraged: Take what you need, vacation plus ten paid holidays! Unplug, recharge, and come back refreshed
• Fun Team and Perks: We do great work and have fun doing it! We take care of our employees… We’ll contribute to your WFH setup and hook you up with occasional at-home perks.
• Opportunity to shape the future of AI-powered features in a high-impact environment.
• Work alongside a talented, collaborative team at the forefront of applied AI.

At StackHawk, we constantly strive to create an environment that allows our employees (Hawks) to do the best work of their lives.
