Senior Engineer

Senior Full-Stack Engineer

Parspec is building the AI and digital infrastructure for the construction materials supply chain. Construction is a $15 trillion industry, yet the systems that underpin the buying and selling of materials remain fragmented, manual, and disconnected. Distributors and rep agencies rely on spreadsheets, PDFs, phone calls, and siloed tools to find new products and quote and manage projects; creating delays, errors, and margin erosion across the supply chain.

Parspec is an AI-native platform that powers how construction products are discovered, bought, and sold. Trusted by more than 300 MEP distributors and rep agencies, Parspec helps project-driven businesses bid faster, win more work, and operate more profitably. By combining product intelligence, AI-powered workflows, and a connected ecosystem, Parspec is laying the foundation for a more intelligent, efficient construction supply chain.

Founded in 2021 and headquartered in San Mateo, California, Parspec has raised $31 million from leading deep-tech and construction-technology investors.

• Own a product domain completely — backend (Django/DRF), frontend (React/Type Script), database schema, APIs, performance, and reliability. No handoffs.
• Make the hard calls. When the right answer isn't obvious — tradeoffs between speed and correctness, schema design, API contracts — that's your call to make and defend.
• Build and ship features independently, collaborating closely with a PM-builder and designer to translate product ideas into production-ready features.
• Contribute to shaping the architecture, domain boundaries, and technical direction of your product area.

• Direct AI agents (Claude Code) at a high level — architect and decompose problems so AI can execute, then review and own the output.
• Manage development across git worktrees and parallel agent sessions.
• Review, refine, and validate AI-generated code to ensure correctness, performance, and maintainability.
• Continuously improve development workflows using AI tools like Claude Code, Code Rabbit, and automated pipelines.

• Ship daily — multiple deploys per day through an automated pipeline with AI code review, E2E tests, and quality gates. You'll merge to main and see it in production the same day.
• Write and maintain high-quality tests (unit, integration, and E2E using Playwright) as a core part of development.
• Ensure all features meet quality standards through automated testing, AI-assisted code review, and manual validation.
• Act as the quality gate for all code shipped, including contributions from AI, PM-builders, and designers.

• Review AI-generated and cross-functional PRs, including contributions from PM-builders and junior engineers.
• Collaborate with design to take features from Figma to production efficiently.
• Work with product and design to challenge assumptions, refine requirements, and improve solutions.

• Set the technical standard — your CLAUDE.md files, testing patterns, and code review bar become the template that newer engineers follow.
• Define best practices for AI-assisted development, testing, and code review. Establish patterns for domain ownership, system design, and engineering workflows as a senior engineer on the team.

• Engineering at Parspec is core to transforming a massive, underserved industry. In this role, you will build and own systems that change how construction materials are quoted, priced, and sold. The ceiling on what one engineer can build has never been higher.
• You will help define a new model for how modern engineering teams operate — leveraging AI to dramatically increase velocity while maintaining high quality. Your work will directly impact how quickly customers can bid projects, win work, and operate more profitably.

• 5+ years of full-stack engineering experience. Django + React preferred — you know both sides deeply, not just tolerably.
• Opinionated about quality — you have a point of view on testing,…
