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. • Hands-on experience prompting, evaluating, and building with LLMs • 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. • Nice-to-Have • Nice-to-Have • Experience with IoT, telematics, or embedded/hardware-adjacent systems. • Familiarity with Kafka, Kinesis, or other high-throughput streaming platforms. • Experience with high-frequency ingest systems and time-series data. • Background with observability tooling (Prometheus, Grafana, OpenTelemetry, DataDog). • Knowledge of SRE practices and automated testing frameworks. • AI-Native Expectations • We use AI coding tools as a professional standard on this team. Here's what that means in practice: • Daily use: You use AI coding assistants (we support Claude Code, Cursor, and GitHub Copilot) for real, substantive tasks: analysis, coding, refactoring, testing, navigating codebases, and documentation. Not just research or autocomplete. • Daily use: • Judgment and ownership: AI-generated code gets the same review you'd give any PR. You are accountable for everything you ship. • Judgment and ownership: • Velocity: We expect senior engineers who use AI well to operate with meaningful leverage — doing more with the same time, taking on problems that would otherwise require a larger team. • Velocity: • Team leadership: You share what works. You automate prompting strategies that others can build on and help teammates earlier in their AI workflow adoption get up to speed. • Team leadership: • Continuous learning: The tooling is changing fast. You stay current and bring recommendations to the team when something would meaningfully improve how we work. • Continuous learning:
Responsibilities
• 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.
Benefits
