Onsemble Full-Stack Engineer- Fully Remote

Are you a full-stack engineer who thrives on owning product features from discovery through launch and iteration? Are you eager for an opportunity to shape the use of modern AI-native software? Do you bring strong technical judgment, a hands-on approach, and an ownership mindset across both frontend and backend systems? If so, then we’d like you to join our dedicated team as a Full-Stack Engineer. 

About Onsemble:

We’re the digital innovation team inside one of the largest wholesale distributors in the U.S., operating with the autonomy of a startup and the scale, customer base, and durability of a major corporation.

Our platform has strong product-market fit today – we have more demand than we can keep up with. The work you lead will immediately impact small and mid-sized contractors and Profit Centers that rely on us every day.

We’re focused on building AI-enabled workflows across a critical but historically underserved layer of the supply chain: SMB contractors and wholesale distribution for the trades. This is a rare opportunity to shape modern, AI-native software that makes real-world businesses meaningfully more productive, profitable, and future-ready.

About the Role: 

The Full-Stack Engineer is responsible for building product across our contractor-facing platform. This role partners closely with Product and Engineering leadership to translate real customer needs into reliable, scalable software — owning features end-to-end across the stack

The Full-Stack Engineer takes a high level of ownership over their responsibilities shipping production code daily, shaping architecture across frontend and backend, and working in an AI-native development model where agentic coding tools are core to how we build.

In this role, you will: 

Own Product & Execution

Own delivery of product features end-to-end, from discovery through launch and iteration.

Partner with Product to scope work and ensure speed, quality, and durability.

Ship production software that supports increasing scale, complexity, and customer adoption.

Act with urgency, being responsive to important and time-sensitive matters and owning their resolution.

Develop AI-Native Software

Actively practice AI-enabled software development in day-to-day work, using tools like Claude Code and similar agentic coding systems to design, build, review, and ship production software.

Use AI to increase leverage, velocity, and code quality — while maintaining strong human judgment around architecture, correctness, and long-term maintainability.

Ensure AI-enabled features are built responsibly, pragmatically, and in ways that deliver real customer value

Own Your Technical Contributions

Contribute to architecture and technical decisions across frontend and backend systems.

Maintain a high bar for code quality, reliability, and maintainability. 

Improve development workflows, tooling, and processes to increase velocity.

Identify risks early and surface them through planning and clear communication.

 Successfully complete required safety and compliance training programs as assigned.

Perform other reasonably related duties as assigned by immediate supervisor and other management as requested.

Solid understanding of backend APIs, data models, and system integrations 

Our ideal candidate will also: 

Have a strong background and familiarity with AI-assisted software development; modern web applications, with deep familiarity in React / Node.js ecosystems, and Claude Code.

Have experience shipping production software used daily by real customers

Demonstrate strong technical judgment:

Be comfortable making architectural decisions and explaining tradeoffs

Possess a practical orientation toward AI: using it to increase leverage and velocity, not novelty

Demonstrate strong instincts for correctness, reliability, and long-term maintainability

Take ownership of their work:

Possess a strong ownership mindset—you take responsibility for outcomes, not just tasks

Be a clear communicator who proactively aligns with engineers, product, and stakeholders. 

Be calm, pragmatic, and able to thrive in ambiguous and fast-moving environments
