Senior Software Engineer, Backend
Flock Safety
• 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. • 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. • You should be a “manager of one” who excels both individually and on a team. • Collaborate with a fully remote team, requiring excellent writing and asynchronous communication skills.

- 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
Benefits
- Flexible PTO: We seriously mean it, plus 11 company holidays.
- Fully-paid health benefits plan for employees: including Medical, Dental, and Vision and an HSA match.
- Family Leave: All employees receive 12 weeks of 100% paid parental leave. Birthing parents are eligible for an additional 6-8 weeks of physical recovery time.
- Fertility & Family Benefits: We have partnered with Maven, a complete digital health benefit for starting and raising a family. Flock will provide a $50,000-lifetime maximum benefit related to eligible adoption, surrogacy, or fertility expenses.
- Spring Health: Spring Health offers a variety of mental health benefits, including therapy, coaching, medication management, and digital tools, all tailored to each individual's needs.
- Caregiver Support: We have partnered with Cariloop to provide our employees with caregiver support.
- Carta Tax Advisor: Employees receive 1:1 sessions with Equity Tax Advisors who can address individual grants, model tax scenarios, and answer general questions.
- ERGs: We want all employees to thrive and feel like they belong at Flock. We offer four ERGs today - Women of Flock, Flock Proud, LEOs and Melanin Motion. If you are interested in talking to a representative from one of these, please let your recruiter know.
- WFH Stipend: $150 per month to cover the costs of working from home.
- Productivity Stipend: $250 per year to use on Audible, Calm, Masterclass, Duolingo, Grammarly and so much more.
