Senior Software Engineer, Backend

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).

• 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.

We prescribe to 90-day plans and believe that good days lead to good weeks, which lead to good months. This serves as a preview of the 90-day plan you will receive if you were to be hired as a Senior Software Engineer at Flock Safety.

• Understand team workflows and processes

• Meet with key stakeholders

• Understand Aviation products and service architecture

• Ability to perform in role with minimal or no guidance

• Participate in API and service architecture reviews

• Contribute to platform architecture improvements and code quality initiatives

• Support platform improvements and scalability projects

• Lead a database and service performance optimization effort

• Act as a technical lead for a mid-sized Go microservice project
  

In this role, you’ll receive a starting salary between $171,000 and $200,000 as well as Flock Safety Stock Options. Base salary is determined by job-related experience, education/training, as well as market indicators. Your recruiter will discuss this in-depth with you during our first chat.
