📋 Description

• Design, build, and maintain backend services for device connectivity, telemetry ingest, health monitoring, and command/control operations — using AI (Claude Code) as a first-class collaborator in your daily development workflow. • Use agentic workflows to dramatically increase delivery velocity without sacrificing quality: from generating service scaffolding, to writing and validating test coverage, to triage and root cause analysis during incidents. • Help define and codify AI-native engineering practices for the Devices Cloud team — establishing patterns the broader org can adopt. • Collaborate with firmware, mobile, and product teams to define APIs and workflows for device-driven features. • Build and own data pipelines for high-throughput telemetry streams using Kafka or similar streaming technologies. • Deliver scalable, resilient microservices on AWS (EKS, Lambda, DynamoDB, SQS, etc.). • Instrument services for observability, reliability, and SLO compliance. • Participate in on-call rotation and live incident response. • Write clean, testable, performant code; contribute to CI/CD automation and improve team-wide engineering standards. • Mentor teammates and help evolve the team's AI-native engineering culture.

🎯 Requirements

• 5+ years of experience building and operating high-quality backend services in Java, Go, Python, or similar languages. • Hands-on experience prompting, evaluating, and building with LLMs — not just autocomplete, but as a genuine development partner. • Deep experience with agentic workflows, prompt engineering, context window management, and MCP/function calling. • A track record of using AI tooling to multiply your own output — faster specs, better test coverage, cleaner code, faster debugging. • Strong experience with microservices architecture, RESTful API design, and distributed systems. • Solid skills with cloud infrastructure (AWS preferred), container orchestration, and production deployments. • Experience with databases (relational and/or NoSQL), caching, and event/streaming systems. • Ability to collaborate across teams and articulate technical tradeoffs clearly. • A genuine drive to define what AI-native looks like for complex, hardware-connected systems — you're not waiting for the playbook, you want to write it.

🏖️ Benefits

• Competitive pay and benefits • Medical, dental, vision, life and disability insurance plans (US and Canada) • 401(k) plan with company matching (US) / RRSP with DPSP matching (Canada) • Employee Assistance Program (EAP) for mental well-being • Flexible PTO, plus several company-wide days off throughout the year • Winter and Summer week-long synchronized company shutdowns • Learning & Development programs • Equipment, tools, and reimbursement support for a productive remote environment • Free Life360 Platinum Membership for your preferred circle • Free Tile Products
