Staff Software Engineer - Connected Device & Platform
This role blends hands-on engineering, technical leadership, and end-to-end ownership, with a strong emphasis on clear technical thinking, concise documentation, and disciplined software practices.
JOB DUTIES
Technical Leadership & Initiative Ownership
Own medium-to-large initiatives end-to-end, from early requirement discovery through design, implementation, rollout, and production hardening; Lead and guide a small pod of 2-3 developers, providing technical direction, task breakdown, and delivery accountability; Balance hands-on development with leadership responsibilities, remaining deeply involved in critical code paths and design decisions; Drive alignment across teams (Product, Firmware, Mobile, QA, SRE, DevOps, Partner teams) to deliver cohesive, cross-layer integrations.
Architecture & System Design
Design and evolve backend services using C#/.NET on Azure within a highly distributed, event-driven architecture; Define clear service contracts using OpenAPI, JSON Schema, and contract-first design principles; Architect and implement event-driven workflows using Event Hubs, Service Bus, IoT Hub, Event Grid, and internal messaging pipelines; Make pragmatic architectural decisions that balance scalability, reliability, delivery timelines, and long-term maintainability
Requirements & Documentation
Lead technical requirement discovery in collaboration with Product and partner teams, translating ambiguous inputs into clear technical designs; Produce concise, high-quality documentation (RFCs, design docs, sequence diagrams, operational notes) that enables fast, confident execution; Establish and enforce clear ownership boundaries, contracts, and integration expectations across systems and teams
Reliability, Automation & Quality
Champion strong software engineering practices: automated testing, CI/CD, safe deployments, and progressive rollouts; Drive improvements in observability, resilience, and operational readiness using metrics, logging, tracing, and alerting; Lead performance analysis and capacity planning for high-throughput device telemetry and fan-out workloads; Participate in incident investigations and ensure learnings translate into durable fixes and platform improvements
Platform & Operational Ownership
Take ownership for features in production, including on-call participation, root-cause analysis, and long-term remediation; Proactively identify platform gaps and propose initiatives to improve scalability, reliability, developer experience, or cost efficiency; Act as a technical point of contact for complex integrations spanning multiple services and teams
YOU MUST HAVE
- 7+ years of experience building and operating production-grade cloud systems, with deep expertise in C#/.NET, distributed systems, concurrency, and scalable service design

- Experience in highly rigorous engineering environments, competitive technical programs, or equivalent applied industry experience demonstrating an ability to be analytical and solve complex engineering problems at a level commonly seen in top tier technical training or high performing engineering roles
- Ability to navigate ambiguity, make sound technical decisions, and maintain momentum in a fast-moving environment
- Experience building connected-device or IoT platforms at scale
- Demonstrated ability to lead small teams without formal people management responsibilities
- Strong written communication skills and a bias toward clear, minimal, and actionable documentation
