This is an SRE role built for people who like to live in the messy middle: device firmware telemetry on one end, cloud ingestion and dashboards on the other, and real-world deployment risk sitting right in the center. You’ll help Flock ship software to a massive IoT fleet faster, safer, and with fewer “what the hell just happened?” moments.
About Flock Safety
Flock Safety is a safety technology platform helping communities take a proactive approach to crime prevention and security. Their hardware and software connect cities, law enforcement, schools, businesses, and neighborhoods into a nationwide public-private safety network, with an emphasis on privacy and responsible innovation. They’re scaling quickly, and reliability is non-negotiable when your products run in the real world, outdoors, and at fleet scale.
Schedule
Full-time, remote (USA)
Department: Engineering (Device SRE team)
On-call rotation included (fleet monitoring and incident response)
Supports device rollouts across cameras and expanding into aviation devices
CJIS certification required if hired (fingerprint-based background check required)
What You’ll Do
⦁ Own software deployment workflows to fleets of IoT devices and ensure reliable rollouts
⦁ Build and improve observability end-to-end: firmware telemetry, ingestion pipelines, dashboards, and alarms
⦁ Instrument health signals and performance metrics directly on devices (counters, events, and firmware telemetry)
⦁ Improve fleet monitoring, root-cause analysis speed, and incident response readiness
⦁ Create and maintain dashboards (Grafana and Sigma) to visualize fleet health and rollout impact
⦁ Design alerts that catch issues early and reduce downtime and noisy false positives
⦁ Streamline rollout workflows to reduce manual steps and shorten response times
⦁ Contribute to code reviews (GitHub and Gerrit) and collaborate across engineering teams
⦁ Modify and maintain infrastructure using Terraform
⦁ Participate in customer calls and field operations ride-alongs to stay grounded in reality
What You Need
⦁ Embedded systems development experience, especially for large or complex IoT or edge devices
⦁ Hands-on device telemetry experience: instrumenting metrics and events directly on-device
⦁ Strong coding skills (examples mentioned: C/C++, Python, R, JS, Java, Groovy) and solid algorithm fundamentals
⦁ Scripting ability (Bash, Python) to automate deployments and operational workflows
⦁ Experience with telemetry ingestion pipelines (device to cloud, batching, retries, reliability patterns)
⦁ Dashboarding and visualization experience (Grafana, Sigma)
⦁ Broad familiarity with databases and logging systems, including SQL and time-series tools (Prometheus or similar)
⦁ Cloud experience (AWS) and strong distributed systems fundamentals
⦁ SRE experience for IoT fleets: monitoring, alerting, and on-call operations
⦁ Strong SDLC instincts: CI/CD, test automation, semantic versioning, branching strategies
Nice to Have
⦁ Infrastructure-as-code experience (Terraform, Ansible)
⦁ High-volume data processing and large-scale storage experience
⦁ Experience with large-fleet device management and distributed telemetry architectures
Benefits
⦁ Salary range: $140,000–$170,000
⦁ Equity (stock options)
⦁ Flexible PTO plus 11 company holidays
⦁ Fully paid health benefits (medical, dental, vision) with HSA match
⦁ 12 weeks paid parental leave (plus additional recovery time for birthing parents)
⦁ Fertility and family benefits (up to $50,000 lifetime maximum for eligible adoption, surrogacy, or fertility expenses)
⦁ Mental health benefits (therapy, coaching, medication support, and digital tools)
⦁ Caregiver support resources
⦁ Work-from-home stipend: $150/month
⦁ Productivity stipend: $300/year
⦁ Home office stipend: one-time $750
If you’re more “I can trace a failure from a firmware event to a cloud metric in one sitting” than “I babysit Kubernetes all day,” this is a strong fit. The job is basically: make the fleet visible, make deployments boring, and make incidents rare.

⦁ Create offline and online evaluation harnesses to enable debugging, regression testing, and PR-gated quality checks
⦁ Build and refine agent tooling patterns: tool use, retrieval, memory, grounding and attribution, and guardrails
⦁ Balance cost, latency, and quality trade-offs while shipping real improvements against measurable metrics
⦁ Partner tightly with product and engineering teams to ship quick wins (tool APIs, prompts, bug fixes) and then scale
⦁ Productionize tracing, alerting, and monitoring so quality and safety are continuously measurable in the wild
⦁ Lead deeper R&D threads (as needed) to improve system performance, including embeddings and multimodal understanding
What You Need
⦁ Hands-on experience building LLM agent systems (tool use, retrieval, memory, grounding, guardrails)

⦁ 5+ years building and shipping ML systems to production
⦁ Backend fluency in Python and JavaScript (TypeScript and/or Golang welcome)
⦁ Experience building web services (FastAPI/Express, REST, SSE, JWTs)
⦁ Cloud infrastructure experience (AWS, Terraform, VPC, networking)
⦁ Experience with backend stores (Postgres, Redis) and strong observability instincts
⦁ Experience building evals at scale, including offline and online harnesses measuring:
⦁ search, retrieval, and recommendation quality
⦁ safety and robustness (security, compliance, red-teaming, regression testing)
⦁ cost, performance, and latency trade-offs
⦁ Preferred but not required:
⦁ durable execution (Temporal, Hatchet)
⦁ OLAP systems (ClickHouse, BigQuery)
⦁ ML inference (PyTorch, Triton, TensorRT) and multimodal domains (text, image, video)
⦁ Compute orchestration (Kubernetes, Prefect, Ray)

Benefits
⦁ Salary range: $200,000–$225,000
⦁ Equity (stock options)
⦁ Flexible PTO (non-accrual) plus 11 company holidays
⦁ Fully paid health benefits (medical, dental, vision) with HSA match
⦁ 12 weeks paid parental leave (plus additional recovery time for birthing parents)
⦁ Fertility and family benefits (up to $50,000 lifetime maximum for eligible adoption, surrogacy, or fertility expenses)
