Onsemble Full-Stack Engineer- Fully Remote

Hajoca Corporation is one of the country’s largest privately-held wholesale distributors of plumbing, heating & cooling, and industrial supplies. Founded in 1858, Hajoca is a company based on the principles of “Service, Integrity, Reliability,” and on relationships of trust and support with teammates, customers, and suppliers. Throughout its history, Hajoca has played an active role in shaping advances in plumbing. However, we attribute our success to two simple truths; a unique business philosophy and talented people. Hajoca is all about the people, who give us our advantage, and who will guide us successfully into the future.

Although Hajoca is a large company, we work in a decentralized environment where each of our locations, called Profit Centers (PCs), is run by the Profit Center Manager as if it were their own small business. A typical Profit Center is the heart of our business and consists of a warehouse, counter, sales office, and (sometimes) a showroom. Our PCs conduct business under unique trade names and offer a customized business approach, honoring what’s special about each local marketplace.

Onsemble is one of those trade names and is looking for a Full-Stack Engineer. This position is fully remote.

Pay for Onsemble Full-Stack Engineer- Fully Remote is between $150,000 and $160,000 per year at this position.


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.
