About the role

Staff Full-Stack Product Engineer focused on Thunderbolt, an open-source AI client for organizations. Ships production code, collaborates with partners and enterprise customers, and turns deployments into reusable product capabilities.

Responsibilities

  • Build and ship full-stack features, integrations, and customer-specific customizations in the Thunderbolt codebase, from front-end UI through APIs, services, and deployment configuration.
  • Work directly with technical partners and enterprise customers to understand environments, requirements, and constraints, and translate them into technical plans and working software.
  • Support pilots, proofs of concept, and early production deployments, including partner-hosted and customer-controlled environments.
  • Diagnose and fix complex issues across application, infrastructure, identity and access, integration, and data-access layers, including bugs and regressions requiring code changes and releases.
  • Maintain customer-specific customizations over time as the core product evolves.
  • Identify customer requests that should become general product capabilities and collaborate with product and engineering to generalize them.
  • Contribute deployment feedback to roadmap and prioritization discussions.
  • Write documentation, deployment guidance, and runbooks for partners.
  • Use AI-assisted development tools judiciously to balance speed with quality, security, and maintainability.

Qualifications

  • 10+ years of professional software engineering experience with Staff-level scope and impact.
  • Strong full-stack skills including modern TypeScript/JavaScript, component-based front-end frameworks, and back-end services, APIs, and integrations.
  • Experience working directly with customers, partners, or systems integrators in a technical capacity where code is written.
  • Experience building or supporting AI-enabled applications (LLM platforms, RAG, agents, enterprise search, or data connectors).
  • Understanding of enterprise deployment concerns: authentication/identity providers, access control, self-hosted/hybrid infra, observability, reliability.
  • Judgment on when to customize vs generalize and when to push back on requests.
  • Clear communication with technical and non-technical stakeholders; ability to set realistic expectations.
  • Strong collaboration across product, design, engineering, and cross-functional teams.
  • Comfort operating independently in an early-stage product environment.
