Senior Software Engineer, Backend

About Flock

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

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).

The Skillset

• 3+ years of PostgreSQL experience (querying, schema design, and performance tuning)
• 3+ years of database architecture experience
• 8+ years of backend development experience, including at least 4+ years using Go in production
• Building scalable, high-performance Go microservices
• Proficiency with message queues, pub/sub systems, or event-driven architectures
• Deep knowledge of Go internals and concurrency patterns (goroutines, channels, sync primitives)
• Expertise in profiling and optimizing Go applications for latency and throughput
• Understanding of Go memory management, profiling, and performance optimization.
• Designing REST and gRPC APIs consumed by multiple clients and services
• Familiarity with observability tools (Prometheus, OpenTelemetry, Grafana)
• Experience in CI/CD pipelines, Docker, and Kubernetes
• Excellent written and verbal communication skills
• Excellent problem-solving and analytical skills

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.
