Product Engineer

Applicants need to be legally allowed to work in the United States. This is a remote position with a strong preference for East Coast (US) time zone. Travel for occasional in-person collaboration is expected.

The Opportunity

We're seeking a skilled, senior level Product Engineer who wants to own meaningful work end-to end, building features and driving from architecture to impact. You’ll be a key contributor to the Common platform, which visualizes networks of solidarity economy funders, organizations, and networks to facilitate collaboration, resource movement, and democratic governance. This is an exciting opportunity to build meaningful technology that serves community-led economic transformation at all scales.

You'll have meaningful ownership over the features you build — from shaping decisions to driving them through to production. You should have experience working across the full stack and taking products from conception to production.

What is One Project?

One Project is a nonprofit social venture. We're building the infrastructure for a new kind of economy — one that benefits everyone. Communities worldwide are already creating alternatives to outdated economic systems that prioritize profit over people and the planet. One Project provides the technology and nurtures the network of alternatives, laying the groundwork for a sustainable, community-driven future.

Why do we need a new economy?

Today’s current economic systems reward profit over people and the planet. This misaligned incentive structure drives the current global polycrisis. When trees are valued more dead than alive, we end up with ecological devastation. When oil remains profitable to extract and sell, we end up with the climate crisis. When war is more profitable than peace, we end up with a military industrial complex that thrives on endless wars. At One Project, we spent our first few years researching these interlinked challenges and realized that we need to address the root cause: we need a new economy with different incentives.

Our history and role

We are not alone in this realization. All around the world, there is a growing ecosystem of communities, movements, and experts who are already working towards a just transition to a new economy. We launched in 2021 with a focus on listening to and supporting these change-makers, and today, One Project is a leading grantmaker in the new economy space ($32M to date). Our current direction is the outcome of what we heard from more than 300 field leaders, dozens of leading organizations, and extensive in-house research: One Project’s role is to build shared infrastructure and a network to move resources to community control. We call this infrastructure Common.

What is Common?

Common is a digital platform that connects people, organizations, and resources to coordinate, make decisions, and grow economic democracy to global scale.

What You'll Do

• Own discrete features end to end — from systems architecture and implementation to iteration and improvement — in close collaboration with design, product, and community stakeholders
• Drive initiatives forward proactively, identifying problems and opportunities, not just responding to them
• Build and scale AI-powered features, including agentic workflows and LLM integrations, as a core part of the product roadmap
• Implement backend services for new and existing features
• Apply security best practices and data privacy principles throughout development
• Continue to contribute to our core UI kit to be robust and reusable across our ecosystem, bringing polish and joy to the app
• Continue to ensure the platform meets accessibility standards (WCAG 2.1 AA)
• Implement best practices in CI/CD, testing, instrumentation, and observability
• Participate in user testing and iterate based on feedback
• Contribute to our ethical open code approach

Some features you might be working on:

• Agentic AI systems through an ethical lense
• Network features, endorsements, recommendations, and trust systems
• Governance / decision-making systems for communities
• Platform scalability & performance
• Financial rails and payment processing
• Security

You may be the candidate we’re looking for if you bring…

Core Experience

• Proven experience as a senior or staff engineer building scalable, modern web applications with React, Next.js, and TypeScript, end to end
• Strong track record of owning and shipping product features with minimal oversight
• Demonstrated ability to rapidly prototype, iterate, and ship while making sound product decisions
• Experience building and integrating AI features in production — including LLMs, agentic systems, or AI infrastructure
• Experience with relational databases (PostgreSQL, MySQL, etc.) and architecture
• Comfort working in ambiguous, fast-moving environments with evolving requirements and structures
• Excellent communication skills, including the ability to translate complex technical concepts for non-technical stakeholders
• Ability to balance technical quality with delivery through a ship-and-iterate mindset

Preferred Experiences

• Experience at a startup, founding a company, or building a product from scratch — you've navigated real product decisions and owned outcomes
• Experience building AI infrastructure, particularly agentic AI systems
• Nonprofit or mission-driven organization experience
• Experience with graph architectures
• Experience implementing financial features with strong security and safety practices; familiarity with Stripe, Unit, Wise, or similar
• Design and user experience acumen
• Strong experience with AI-assisted development tools (Claude Code, Cursor, Windsurf, or similar)
• Understanding of open source and ethical code licensing approaches

You don't need to check every box — if you meet most of these, we encourage you to apply.

At One Project, team members bring our values to life when they:

• Drive clarity by connecting work to purpose and help others understand the "why" behind decisions.
• Support teammates' success as readily as their own, sharing knowledge and pitching in across boundaries.
• Communicate directly with empathy, giving and receiving feedback in service of growth.
• Actively seek diverse perspectives and create space for others' unique strengths to shine.
• Build trust through consistent follow-through and transparent communication.
• Find creative solutions by embracing nuance and moving beyond either/or thinking.
• Deliver excellence through careful work, measurable results, and continuous improvement.

Working at One Project

One Project strives to be a place where a diverse mix of talented people are empowered to bring their full, authentic selves to do their best work. Our goal is to build a team that reflects the world we live in and celebrates multiple approaches and points of view. We believe diversity drives innovation and every idea deserves consideration and respect. We have an unwavering commitment to inclusion across educational background, gender identity and expression, sexual orientation, religion, ethnicity, age, citizenship, socioeconomic status, disability, and veteran status.

Development Acceleration & AI Tools

One Project encourages the responsible use of AI-assisted development tools in accordance with our Information Security & Technology Policies. The developer will have access to tools like Claude Code to aid them on a day to day basis. All use of AI tools must comply with our LLM Guidelines, particularly regarding data privacy, security, and proper review of generated code. The developer will be expected to use these tools judiciously while ensuring all final code meets our quality standards and security requirements.

We expect to hire for this role in the $175,000-200,000 range. The final offer will depend on experience, skills, and internal equity. One Project offers a comprehensive and competitive benefits package including health, dental, and vision insurance, generous paid time off, and an employer retirement contribution.
