Senior Optomechanical Engineer

Location: Onsite in Broomfield, Colorado
Compensation: 115,000 to 130,000 USD base salary, plus equity and full benefits
US Person Required

Darwin Space are partnered with an exciting space company who are building next generation optical communication systems for space applications. They are expanding their engineering team with multiple Senior Optomechanical Engineers. Their work involves designing space qualified optical assemblies that must survive extreme launch loads, operate with micron level stability on orbit and be produced in a scalable, cost effective manner.

They are looking for engineers with strong optomechanical fundamentals, real industry experience and a track record of owning designs from concept through integration and testing. This role is ideal for someone who thrives in a fast moving environment, can take ambiguous requirements and turn them into clear design actions, and wants to contribute directly to a new generation of space based communication technology.

They value engineers who bring stability in their career history, hands on capability and the judgment that comes from real hardware experience.

Role Overview

As a Senior Optomechanical Engineer, you will be responsible for mechanical and optical system design, alignment strategies, tolerance analysis and performance verification for precision optical hardware intended for space environments. You will work across optical, mechanical, electrical and controls disciplines to ensure that your designs deliver stable, repeatable optical performance under vacuum, thermal cycling, vibration and mechanical stress.

You will own the full lifecycle of optomechanical assemblies including concept development, CAD design, analysis, prototyping, alignment strategies, environmental testing and release to production. You will mentor junior engineers, represent optomechanical design in cross functional discussions and support both ground based and flight system development.

This is a hands on, senior individual contributor role with significant ownership and visibility.
