About the role

  • We've invested heavily in forward-deployed engineers at the customer edge.
  • We're hiring a Principal Platform Engineer to serve as a platform leader: someone with deep expertise in software infrastructure and architecture who has built and operated scaled, high-uptime systems.
  • This person will help us scale our backend, raise our reliability and performance bar, and provide sharp technical judgment on infrastructure changes.

Responsibilities

  • Drive reliability and uptime: Establish and improve reliability practices (SLOs/SLIs, incident response, postmortems, on-call effectiveness, capacity planning).
  • lead initiatives across databases, APIs, caching, async processing, and observability.
  • Build leverage for the team: Create scalable primitives (libraries, patterns, tooling, platform services) that enable product and forward-deployed teams to ship faster with less risk.
  • lead by example through hands-on delivery.
  • Partner cross-functionally: Work closely with Product, Security, and field-deployed engineers to balance edge/customer urgency with platform durability.
  • Lead at least one high-impact initiative that materially improves uptime, performance, or developer velocity.
  • Performance leadership: Identify systemic performance bottlenecks; lead initiatives across databases, APIs, caching, async processing, and observability.
  • Mentor and set the technical bar: Coach engineers on architecture, operational maturity, and high-quality execution; lead by example through hands-on delivery.
  • Experience building internal platforms that enable other engineers (tooling, CI/CD, shared services, paved roads).

Requirements

  • 8+ years of professional software engineering experience, with significant time owning backend/platform systems in production.
  • Track record of leading large technical initiatives across teams or across a complex codebase.

Nice to have

  • Prior experience as a Staff/Principal Engineer (or equivalent scope) at a high-scale infrastructure org.
  • Depth in one or more of: SRE / reliability engineering, performance engineering, database scalability, multi-tenant architectures, zero-downtime migrations.
  • Experience in or affinity for manufacturing, industrial software, or hard-tech customer environments.
  • Team outings, group lunches, open office, happy hours.
  • Paid holidays, sick days.

Company info

  • Create scalable primitives (libraries, patterns, tooling, platform services) that enable product and forward-deployed teams to ship faster with less risk.
  • Own platform architecture at scale: Evaluate and evolve our backend architecture to support growth in customers, data volume, and product surface area.
  • Evaluate and evolve our backend architecture to support growth in customers, data volume, and product surface area.
