- Maintain and elevate the existing company culture across your team

People and Organization

- Create a psychologically safe environment and provide support and motivation to the team
- Proactively check in with team members to ensure that their performance is good and their needs are met

- Proactively resolve interpersonal conflicts within the team

## Requirements

- 8+ years of experience in software development
- 3+ years of people management experience in a startup environment

The Team We're a driven team, who've helped build some incredible companies (Tesla, Waymo, Google, Meta, Amazon, Dropbox, Airbnb and many more). And now we're tackling an exciting problem space ripe for disruption. Our team is small, but our ambitions are big. So we only hire the absolute best and try to learn every day while having a lot of fun.

- **Headquarters**: San Francisco, California, United States
- **Founded**: 2020
- **Founders**: Idan Mintz (Co-Founder and CTO); other co-founders not publicly named

## Core Business
- **Primary industry**: Supply Chain Management / Procurement Software (AI-native)
- **Target customers**: B2B, Enterprise (manufacturing companies with complex direct materials sourcing), specifically procurement, engineering, and supplier teams
- **Mission or purpose statement**: To connect engineering, sourcing, and suppliers in one AI-powered operating system, enabling faster product launches at lower cost.

## Products & Services
- **LightSource Platform (AI-Native Direct Materials OS)**: A SaaS platform that ingests unstructured data (BOMs, drawings, quotes), creates a revision-managed item master, and uses AI to model optimal award decisions across cost, capacity, quality, and resilience. Automates RFQ-to-award workflows, synchronizing engineering, procurement, and suppliers.

## Market Standing

## Competitive Advantages
- **AI-native direct materials focus**: Unlike general procurement tools, LightSource is purpose-built for the complexity of direct materials (BOMs, drawings, revisions), using AI to turn messy inputs into a defensible award.
- **Engineering-Procurement-Supplier sync**: A single operating system that eliminates data silos and revision chaos across the NPI process.
- **Speed of deployment**: "Up and running in weeks with results in the first sourcing event" (BRP quote).
- **Defensible awards**: AI models optimal award based on cost, capacity, quality, and resilience, not just price.
- **SOC 2 & SSO**: Enterprise-grade security and compliance.

## Strategic Focus
- **Product-led growth**: Continuing to expand the platform's AI capabilities for direct materials sourcing.
- **Global expansion**: Rolling out with large manufacturers (BRP, Canada Goose, Arxada) and targeting "innovative manufacturers."
- **Tariff opportunism**: Enabling customers to act quickly on tariff windows opening and closing (as noted by Arxada CPO).

## Why Work Here
- **Culture**: Rated 5.0/5.0 on employer review sites (3 reviews); Culture score 5.0, Career 4.5, Work-Life 4.0, Compensation 4.0.
- **Team**: Lean, high-growth environment (53 employees, +75% YoY). Strong technical team (32% of headcount in technical roles). Many hires from McKinsey, Meta, Google, Microsoft, Salesforce.
- **Remote/Hybrid**: Offices in San Francisco (HQ), Denver, and Ukraine. Likely hybrid/remote-friendly given distributed team.
