Who is 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 The pipeline team is seeking a seasoned Senior Software Engineer to bolster our efforts to accommodate the rapid expansion of our workload. Flock is continuing to expand to more customers and with that comes more data. Today, Flock processes around 2 billion assets daily in real time (including License Plate Recognition data, audio clips, and images—no raw video). For Flock to keep momentum, we need to keep the pipeline latency low, handle massive asset volumes, solve scalability issues and build new features that support the business. This role centers on data processing and architectural design within a high-scale backend ecosystem. The Skillset Love writing code and have extensive experience doing so. Motivated by taking an unknown problem, sinking your teeth in, and coming up with a plan of attack (ownership mindset). Deep proficiency in TypeScript backend patterns (Node.js, async behavior, typing complex data structures). Proficiency or a strong willingness to scale up quickly in Go, as the team is actively migrating to be more Go-heavy in the future. Experience with microservice-oriented architecture and designing distributed systems at scale (handling heavy traffic load and massive data ingestion). Strong backend/database and pub/sub experience, leveraging Postgres DB, OpenSearch, DynamoDB, and Redis. Ability to tune and optimize PostgreSQL performance when multiple services are interacting with it. Experience with AWS and cloud tooling such as Kubernetes (EKS), SQS, SNS,, and Docker. Excellent cross-functional communication and collaboration skills, with a proven track record of working tightly with adjacent teams such as Hardware, ML, Web,, Mobile, and Data Science. Experience acting as a domain expert, mentoring junior engineers through code reviews, finding teaching moments, and making the success of the team a bigger priority. 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.
