About The Position

Flock Safety is the leading safety technology platform, helping communities thrive by taking a proactive approach to crime prevention and security. Our hardware and software suite connects cities, law enforcement, businesses, schools, and neighborhoods in a nationwide public-private safety network. Trusted by over 5,000 communities, 4,500 law enforcement agencies, and 1,000 businesses, Flock delivers real-time intelligence while prioritizing privacy and responsible innovation. We’re a high-performance, low-ego team driven by urgency, collaboration, and bold thinking. Working at Flock means tackling big challenges, moving fast, and continuously improving. It’s intense but deeply rewarding for those who want to make an impact. With nearly $700M in venture funding and a $7.5B valuation, we’re scaling intentionally and seeking top talent to help build the impossible. If you value teamwork, ownership, and solving tough problems, Flock could be the place for you. We are seeking an experienced and skilled Senior Software Engineer with a deep understanding of Golang, distributed backend systems, and PostgreSQL. To be right for this role, you should be a “manager of one” who excels both individually and on a team. This role involves architecture, backend Go development, and honing the integrity and performance of a PostgreSQL database where Go services are not the only clients. And because we’re a fully remote team, you should be an excellent writer and asynchronous communicator. As a senior member of our engineering team, you will have the opportunity to build performant, reliable backend systems, contribute to architectural discussions, and deliver features that matter. The ideal candidate will have experience designing and scaling production-grade Go applications, building microservices and APIs, and tuning systems for high performance and reliability. This position is fully remote (USA only).

Experience in CI/CD pipelines, Docker, and Kubernetes
Excellent written and verbal communication skills
Excellent problem-solving and analytical skills
Ability to obtain and maintain Criminal Justice Information Services (CJIS) certification as a condition of employment. Applicants must meet all FBI CJIS Security Policy requirements, including a fingerprint-based background check.
