Scope of responsibilities

Take ownership of the end-to-end product experience

Reliability is critical. Our customers and their factory teams need to trust the systems on high-stakes production lines. In this role, you'll be responsible for writing clean, efficient, and maintainable code in a new application framework built on ReactRouter. Your work will directly shape a seamless and delightful user experience. When things don’t go as planned, you’ll proactively dig into the root causes and implement effective, pragmatic solutions.

Highly organized with the ability to manage multiple priorities

Engineers often balance several projects at once while also responding to production issues in real time. You’ll work closely with the project management team to continuously evaluate priorities and ensure we stay aligned with customers’ production timelines.

Be a collaborative teammate

This is not a solo role. You'll work hand-in-hand with our engineering and product teams to coordinate feature releases and improvements. Clear, direct communication is essential - as is giving and receiving feedback and striving for continuous improvement together.
