Staff Engineer, Software Architect

This Staff Platform Engineer role focuses on owning and evolving a multi-tenant automotive SaaS platform that powers dealer onboarding, inventory management, and real-time transaction processing. You will act as a technical steward for the engineering organization, ensuring the platform remains healthy, secure, scalable, observable, and maintainable as the company grows. The position emphasizes platform ownership, reliability, security, modernization, and safe delivery practices, with hands‑on exposure to agentic AI systems as a capability within the broader platform.

You will work across teams, influence engineering standards, and help shape how engineering operates going forward, rather than focusing primarily on feature development.

• Design, build, ship, and operate agentic AI systems, including autonomous, tool‑using agents that observe platform state, reason over dealer context, and act through production APIs.
• Serve as a hands‑on platform engineer responsible for the health, security, reliability, and maintainability of a multi‑tenant automotive SaaS platform.
• Continuously identify, triage, and remediate security vulnerabilities, including managing dependencies, applying timely patches and upgrades, and enforcing secure‑by‑default practices.
• Upgrade and modernize frameworks, runtimes, and platform components to keep the stack current, stable, and safe to ship.
• Lead and drive adoption of an agentic development harness to accelerate delivery and improve developer productivity across the organization.
• Own and improve production monitoring and observability, including defining and maintaining SLOs, error budgets, and telemetry to ensure reliable operations.
• Establish, document, and enforce engineering standards, coding guidelines, and best practices across multiple engineering teams.
• Define and manage CI/CD pipelines and release management processes, including quality and security gates, rollback strategies, and progressive delivery mechanisms.
• Champion safe releases by designing checks and balances that gate production, ensuring changes are tested, observable, and reversible.
• Lead SRE practices such as on‑call operations, incident response, and post‑incident reviews to minimize customer impact and improve system resilience.
• Design and maintain instrumentation and guardrails so that production failures degrade gracefully and fail safe rather than fail loud.
• Collaborate with engineering teams to modernize legacy systems, including evolving a monolith into microservices and microfront ends using domain‑driven design and strangler patterns.
• Plan and execute monolith‑to‑microservice extractions, including dual‑write validation, traffic splitting, canary and per‑tenant rollouts, and shared database decomposition.
• Contribute to both backend services and frontend applications, owning performance, monitoring, and reliability across the stack.
• Review architecture and code across multiple teams, identifying technical risks early and guiding engineers toward robust, maintainable solutions.
• Integrate with third‑party APIs at scale, designing resilient patterns for REST, SOAP, webhooks, idempotency, retries, and backoff strategies.
• Design and operate data models using both relational and No
  
  SQL databases, ensuring appropriate schema design and access patterns.
• Write clear, actionable design documents, ADRs, and runbooks that enable other engineers to implement solutions without extensive meetings.
• Promote reusable abstractions and platform capabilities while avoiding unnecessary complexity and over‑engineering.
• Operate security tooling such as dependency and vulnerability scanners, SAST/DAST, and container image scanning in production environments.
