About Observable Space

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.

About the Role

We are seeking a highly skilled and experienced Electrical Engineer to join our dynamic team. This role will involve deep engagement with our product line of telescopes and orbital hardware. The ideal candidate will have a strong background in circuit fundamentals, with specific expertise in printed circuit board (PCB) design, wire harnessing, circuit simulation, and design for manufacturing (DFM). This role will report to the Director of Electrical Engineering.

What You'll Do

• Design and develop electronic circuits, PCBs, and wire harnesses for telescope and orbital hardware.

• Design and own complex multi board computers utilizing state of the art high performance SoCs and FPGAs.

• Perform circuit simulations, schematic capture, and layout reviews to ensure functionality, reliability, and manufacturability.

• Apply best practices for signal integrity, EMI/EMC compliance, and power distribution.

• Build and test prototypes, including PCB bring-up, rework, and modification (soldering, trace cutting, wiring).

• Develop and execute test procedures for electrical subsystems, ensuring design meets performance and safety requirements.

• Perform root cause analysis and debugging using oscilloscopes, logic analyzers, multimeters, and spectrum analyzers.

• Collaborate with mechanical, software, and manufacturing teams to integrate electrical designs into complete systems.

• Define and document electrical interfaces, block diagrams, product requirements, assembly drawings, and other supporting documents to support cross-team integration.

• Support design for manufacturing (DFM) and design for reliability (DFR) reviews to ensure smooth transition from prototype to production.

What You'll Bring

• 6+ years of experience in a relevant electrical engineering role.

• Strong understanding of DC power circuits, common interfaces/protocols (I2C, SPI, CAN, Ethernet, MIPI, PCIe), ADCs, microcontrollers, opamps, and transistor circuits.

• Excellent circuit debugging skills, knowledge of power supplies, oscilloscopes, logic analyzers, spectrum analyzers, multimeters.

• Comfortable with PCB rework including soldering, staking, cutting traces, preparing wires.

• Experience with circuit simulation and design tools.

• Understanding of circuit board construction, transmission line structures, signal integrity, EMI/EMC, via types, and component types.

• Experience with Altium (or similar PCB software) and LTSpice (or similar software).

• Understanding of wire harnessing fundamentals such as electrical checkout, hi-pot testing, impedance characterization, and shielding.

• Acute product sense, placing an emphasis on design for manufacturing and field reliability.

• Ability to thrive in a fast paced dynamic environment where rapid prototyping is the norm.

• An iterative mindset- perfect is the enemy of good.

Preferred Qualifications

• Experience with signal integrity simulation software (Hyperlynx, SIwave).

• Real world experience with CMOS image sensors or other high data rate collection sensors.
