Staff Software Engineer, Agents

Every community deserves to be safe, it’s a fundamental right. Our mission is simple - to build technology that reduces crime and protects privacy. Flock partners with cities, businesses, schools, and neighborhoods to help protect where people live, work, and play. Last year, Flock technology supported over 1 million criminal investigations. We've also helped solve approximately 20% of reported crimes in areas where we're deployed, and have played a role in locating more than 10,000 missing people.

We are a high-performance team united by urgency, ownership, and a shared commitment to meaningful impact. The work is fast-paced and the expectations are high. We push beyond perceived limits, support each other, and hold ourselves accountable to delivering results that matter.

With over $1B in funding and an $8.3B valuation, we are scaling with intention and investing in the people who will help us build what others said could not be done. At Flock, you will find the opportunity to grow quickly, take on real responsibility, and contribute to something bigger than yourself.

The Opportunity

Flock Safety is looking for a Staff Software Engineer, Agents to help build the next generation of AI-powered investigative products.

Our team is building Nightshift, a conversational investigative agent that helps law enforcement investigators surface critical evidence, reason across complex data, and close cases faster. Nightshift sits at the intersection of large-scale data systems, production AI, agentic workflows, and high-stakes customer use cases where reliability, transparency, and speed matter.

You will join a small, senior team that combines application development and ML testing expertise. We are looking for another high-level engineer who can accelerate our agent development, raise our engineering bar, and help turn our work into a reusable AI platform for other product teams across Flock.

This is not a research-only role. You will ship production systems, improve agent reliability through testing and evals, build infrastructure for faster iteration, and design backend systems that allow AI products to safely and reliably operate on top of Flock’s large-scale data platform.

You will be expected to own ambiguous, high-impact technical problems end to end, influence architecture across teams, and serve as a multiplier for engineers building AI-powered customer experiences at Flock.

The Skillset

• Strong backend/software engineering fundamentals

• Experience shipping production code and customer-facing products at scale

• Experience with LLMs, AI systems, and agentic workflows in production

• Familiarity with tools like LangChain, CrewAI, OpenAI SDK, or Claude Agents SDK

• Strong product and customer mindset

• Comfortable working in ambiguity and startup-style environments

• Experience with cloud infrastructure, databases, and backend systems

• Strong collaboration, ownership, and communication skills

• RAG systems

• Multi-agent systems

• Voice agents

• AI evals and reliability testing

• AWS, Kubernetes, ClickHouse, WebSockets/WebRTC

Feeling uneasy that you haven’t ticked every box? That’s okay; we’ve felt that way too. Studies have shown women and minorities are less likely to apply unless they meet all qualifications. We encourage you to break the status quo and apply to roles that would make you excited to come to work every day.
