Principal Software Engineer

Essential Duties and Responsibilities include the following. Other duties may be assigned. Architecture & Engineering

• End-to-end architecture: services, APIs, data model, event streams, infrastructure, security.
• Production code across a polyglot stack: Java/Spring Boot microservices, Node.js/React applications, serverless designs, and Python tooling.
• Build-vs-buy decisions, coding standards, and pragmatic technical-debt reduction.

Production & Reliability

• Availability, observability, alerting, and incident resolution.
• Escalation point of last resort. You take ultimate responsibility for uptime and resolution.
• CI/CD, multi-environment release management, and production deploy authority.
• Blameless post-incident analysis; every incident becomes a runbook, a test, or a design change.

Infrastructure & Data

• The AWS footprint: Kubernetes workloads, infrastructure-as-code, IAM, secrets, and cost.
• The data layer: PostgreSQL at telemetry scale, supporting stores, and the event-streaming topology.
• The analytics pipeline and data lake.
• The edge-to-cloud pipeline: device connectivity, ingestion, the device-cloud message contract, and firmware coordination with embedded engineering.

Security

• Identity and access, enterprise SSO, multi-tenant isolation, secrets, least-privilege, dependency hygiene.
• Represent the platform in customer security evaluations.

Leadership

• Architectural direction, design review, and code-review quality gates.
• Independent command of every service and deployment path.

AI-First Engineering

• Own how the platform is built with AI: agent conventions, knowledge base, agent-generated tests, tooling, and guardrails.
• Drive greater agentic capability across engineering and measure it.
• Ship AI capabilities in the product where they create measurable value., * The Principal Software Engineer is an office-based role. Regular, predictable on-site attendance is required. Eligibility for up to one (1) remote workday per week may be permitted, subject to business needs and departmental guidelines.
• Perform core job responsibilities through regular in-person collaboration, including participation in meetings, team discussions, and cross-functional coordination.
• Collaborate with fellow team members and leadership in a shared work environment to support innovation and timely decision-making, problem-solving, and operational effectiveness.
• Maintain a consistent on-site presence to support and respond to day-to-day business needs, including attendance of scheduled meetings and real-time collaboration as needed to ensure alignment of department and company priorities.
• Meet regularly with manager in-person to align on workload, priorities, performance, and ongoing professional development.

• Bachelor’s degree required.
• Ten or more years related experience required.
• Production accountability. 10+ years shipping and operating production software at principal/staff scope; has personally led resolution of high-severity incidents on systems they built.
• Polyglot backend depth. Expert in Java, and either Node.js/TypeScript or Python, and able to debug the other.
• Kubernetes in production. Hands-on operation of production workloads on AWS; deep AWS fundamentals.
• AI-native. Coding agents are your default. You can show how you make a repository produce shippable agent output, and where you draw the line.
• Distributed-team leadership. Has led a distributed engineering team and owned the quality gate for code they did not write.
• Event streaming at depth. Production experience with Kafka or equivalent, including ordering and back-pressure failure modes.
• PostgreSQL at scale. Schema design, migrations, query performance, high-volume telemetry.
• Writes clearly. Runbooks, ADRs, and design docs are part of the job.
• AWS serverless design (Lambda, event-driven pipelines, Aurora); strong React; infrastructure-as-code and CI/CD ownership at depth; security architecture (tenant isolation, IAM, secrets); has led a live migration from containers to serverless strongly preferred.
• IoT / connected-device experience (fleet management, telemetry, cellular edge hardware); industrial protocols (e.g., Modbus) and the ability to read embedded C; data-lake experience (Spark, Athena, Parquet); enterprise multi-tenant B2B SaaS; building LLM-powered features or agent tooling preferred.
• This role carries after-hours availability expectations for production-critical incidents, consistent with the escalation-of-last-resort duty above.

The hours for this position are 8:00am - 4:30pm, Monday through Friday. We are proud to be an Equal Opportunity Employer. Company-paid background check required upon hire.
