Senior Opto-Mechanical Engineer, Photonics

At Observable Space, we're redefining how humanity observes and connects with the universe. We're a vertically integrated, high-growth, space technology company building industry-leading precision optics platforms for Earth and in space. Our systems are trusted by NASA, JPL, SpaceX, Boeing, Raytheon, and the US DoD, among others, and power the work of leading research institutions.

We combine precision opto-mechanical hardware, embedded computing, cloud orchestration, and developer-friendly APIs into world class products. From advanced ground stations, on orbit sensor suites, free space optical lasercom, to distributed compute platforms, we deliver the foundational systems enabling continuous, real-time navigation, observation, and communication in space.

Observable Space is backed by top-tier institutional investors including Lux, Upfront Ventures, RTX Ventures, Detroit Venture Partners and Embedded Ventures.

As a Senior Opto-Mechanical Engineer, Photonics, you will work across our full product line, from robotic ground-based telescope systems to future space-based optical payloads. You will design and integrate precision opto-mechanical systems that enable advanced photonic performance, including fiber-coupled systems, laser-based subsystems, and high-sensitivity imaging assemblies.

This role is deeply hands-on: you will develop precision assemblies, work closely with optical and electrical engineers, support alignment and integration, and debug complex system-level issues at the intersection of optics, mechanics, and environment. You will report to the Head of Mechanical Engineering (or Optics/Hardware Lead, depending on org structure).

- Ability to thrive in fast-paced, iterative development environments.

- Experience with photonics systems, including fiber alignment, laser stabilization, and optical coupling techniques.

- Direct experience designing, integrating, and testing Adaptive Optics (AO) systems and Wavefront Sensors.

- Familiarity with vibration isolation and environmental constraints (thermal cycling, vacuum, launch loads).

- Experience with STOP analysis and system-level performance verification.

- Knowledge of system engineering workflows, including interface control documents (ICDs) and verification processes.

- Experience working in early-stage or startup environments with rapid prototyping cycles.

- Basic scripting or automation (Python, MATLAB) for analysis, alignment, or test workflows.

- Experience with Wavelength Division Multiplexing (WDM) and the opto-mechanical challenges of high-bandwidth modem and waveform management systems.
