Full-Stack Developer


OpStart is searching for an innovative and experienced full-stack engineer to lead technology execution in line with our mission.

Our product today is a finance department in a box for startups – we take over management of all accounting and finance tasks, allowing entrepreneurs to focus on their product and growth while OpStart keeps their books clean and compliant. Delivering this product involves a combination of manual processes, software automation, and communication with customers. Our technology team is focused on improving this product by reducing the manual effort and communication required to deliver it.

Our initial priority is launching a platform that makes finance more accessible for entrepreneurs. We are seeking to empower founders by providing a “home page for finance” that allows them to access information, track tasks, and meet deadlines in one central location.

Additionally, our product and technology teams work closely with our accounting team to identify inefficiencies in their execution processes and develop automations to eliminate them.

Our goal is to streamline OpStart’s operations by facilitating communication and make life easier for clients. In the long-run, the product can become a standalone tool for entrepreneurs trying to understand their own financial and back-office needs.


This engineer will help us build and maintain a seamless Client experience. The role reports directly to the VP of Product and the tech department currently consists of 3 contract developers that have been working on the MVP since Q3 of 2022. We currently host one standup per week and one retro after each project so asynchronous transparency and comfort with autonomy is key.
