Full-Stack Engineer

About Parspec

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.

The Opportunity

We are seeking our first Bay Area Engineer to help build a new kind of engineering team-one where two people (an engineer and a PM-builder), powered by AI, can ship as fast as a traditional five-person team.

This is a hands-on role for someone who enjoys owning entire product domains end-to-end and shipping production code daily. You will be Engineer #1 for the Sales Rep Portal, owning the Sales Management & Pricing domain from backend to frontend.

You will work directly with an experienced PM-builder and designer to ship the Sales Rep Portal MVP-a product that transforms how electrical distributors and manufacturers' reps quote and price projects.

This is a senior individual contributor role focused on ownership, velocity, and quality. The ideal candidate thrives in an AI-native development environment, directing AI agents to produce high-quality code while maintaining strong engineering judgment and standards.

What You Will Achieve and Key Responsibilities

Domain Ownership & Product Development

• Own the Sales Management & Pricing domain end-to-end, including backend (Django/DRF), frontend (React/Type Script), database design, APIs, and infrastructure
• Build and ship features independently without relying on separate frontend/backend teams or handoffs
• Collaborate 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 the Sales Rep Portal

AI-Driven Development & Execution

• Direct AI agents (Claude Code) to generate code, orchestrating multiple parallel development workflows
• 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

Shipping, Testing & Quality

• Ship code to production daily through an automated CI/CD pipeline
• 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 bar for all code shipped, including contributions from AI, PM-builders, and designers

Collaboration & Code Review

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

Systems & Playbook Development

• Define best practices for AI-assisted development, testing, and code review
• Create and maintain CLAUDE.md files and development conventions that scale across the team
• Establish patterns for domain ownership, system design, and engineering workflows as the first engineer in the Bay Area

Why This Matters

• Engineering at Parspec is core to transforming a massive, underserved industry. In this role, you will build foundational systems that change how construction materials are quoted, priced, and sold.
• 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.

Who You Are

Mandatory Qualifications

• Full-stack engineering experience (Django + React preferred, or strong experience in similar frameworks with willingness to learn)
• Experience building and shipping production software used by real customers
• Strong proficiency with modern AI coding tools (e.g., Claude Code, Copilot, Cursor) as a core part of your workflow
• Ability to architect systems, review AI-generated code, and intervene when necessary
• Strong product mindset-you think beyond tickets and focus on solving user…
