No BS summary

Staff Backend Engineer needed to own the technical direction of the Order Management module. Requires extensive experience building and operating backend systems, leading complex distributed systems architecture, and deep hands-on experience with event-driven architectures (Kafka). Must have strong Node.js expertise and thrive in ambiguous, greenfield environments. Experience in compliance-sensitive domains is a plus.

What you'll do

  • Design the order state machine (Draft → Internal Review → Pending Signature → Approved/Declined), approval workflows, idempotent transitions, and audit events.
  • Own the PDF generation pipeline, including templates, reusable fragments, bundles, placeholder resolution, versioning, and scoping across the contract library.
  • Design and own reliable integrations with internal planning systems and DocuSign, ensuring reliable synchronization through asynchronous processing, retries, reconciliation, and observability.
  • Drive architectural alignment through design docs and RFCs.
  • Define cross-cutting engineering patterns, review complex technical proposals, and enable senior engineers to make sound technical decisions.
  • Help define how the team adopts AI tooling responsibly-establishing patterns for AI-assisted development, code review standards for generated code, and knowing when AI accelerates versus when it misleads.
  • Design performant APIs for dashboards, search, and pipeline visibility that remain scalable and easy to evolve.
  • Balance business needs with long-term technical sustainability, creating alignment across Product, Legal, Operations, and Engineering.
  • Design systems that remain reliable under failure while continuously improving observability, monitoring, and operational excellence.

What they require

  • You have extensive experience building and operating backend systems in production and have led the architecture of complex distributed systems.
  • You have deep hands-on experience with event-driven architectures, particularly Kafka, and a strong understanding of idempotency, event sourcing, state machines, and asynchronous workflows.
  • You've designed and operated production-grade microservices and are comfortable with distributed systems challenges such as retries, reconciliation, eventual consistency, and failure recovery.
  • You bring strong Node.js backend expertise, including asynchronous programming, testing, and operating services in production.
  • You thrive in ambiguous, greenfield environments and are comfortable defining technical direction where no established solution exists.
  • You take ownership of complex technical problems and bring clarity where requirements or solutions are initially ambiguous.
  • You influence engineers through technical leadership, communicate ideas clearly through design docs and RFCs, and make pragmatic architectural decisions that balance scalability, maintainability, and business impact.
  • You identify architectural risks early and simplify complex systems before they become delivery bottlenecks.
  • Experience in compliance-sensitive domains such as contracts, document workflows, or e-signature platforms like DocuSign is a plus.
