Astranis is a company that designs, builds, and operates advanced satellites for high orbits to provide dedicated, secure communications networks.
<div class="content-intro"><p>Astranis builds advanced satellites for high orbits, expanding humanity’s reach into the solar system. Today, Astranis satellites provide dedicated, secure networks to highly-sophisticated customers across the globe— large enterprises, sovereign governments, and the US military. With five satellites on orbit and many more set to launch soon, the company is servicing a backlog of more than $1 billion of commercial contracts.<br><br>Astranis is the preferred satellite communications partner for buyers with stringent requirements for uptime, data security, network visibility, and customization. Astranis has raised over $750 million from some of the world’s best investors, from Andreessen Horowitz to Blackrock and Fidelity, and employs a team of 450 engineers and entrepreneurs. Astranis designs, builds, and operates its satellites out of its 153,000 sq. ft. headquarters in Northern California, USA.</p></div><div class="section page-centered"> <div class="section page-centered"> <div class="columnLayout single" data-layout="single"> <div class="cell normal" data-type="normal"> <div class="innerCell"><strong>Senior Harness Design Engineer</strong> <p>As a Senior Harness Design Engineer at Astranis, you will own the design of the wire harnesses that keep our spacecraft alive on orbit, translating electrical architecture into manufacturable, flight-reliable harness designs built to survive launch and the full mission life in geostationary orbit. You will take harnesses from schematic capture through production release, working across low-voltage, high-voltage, and RF interconnects.</p> <p>This is a multidisciplinary role built on electrical design depth. You'll bring strong command of harness and electrical design, literacy in the mechanical side of routing and packaging, and the technical range to partner across nearly every part of the vehicle, from avionics and power to propulsion, payload, production, and test. It's a senior seat for someone who owns problems end to end, drives reliability through root-cause analysis, and raises the bar on how flight harnesses get designed and built.</p> </div> </div> </div> <div class="columnLayout single" data-layout="single"> <div class="cell normal" data-type="normal"> <div class="innerCell"> <h4 id="JobDescriptionSeniorHarnessDesignEngineerI/II-WhatYou'llDo">What You'll Do</h4> <ul> <li data-uuid="3dad8752-d90a-4eb4-a0e2-ef6243096455">Own harness architecture and design from concept and schematic capture through drawing packages and production release</li> <li data-uuid="7f703a9e-0b9b-4ea1-8e1f-4c06ee29e4dc">Perform the core electrical analysis behind reliable harnesses: wire sizing, voltage-drop budgets, protection and fuse coordination, derating, and connector/component selection</li> <li data-uuid="e02b5843-e7d8-4ed0-bd20-160ba427c086">Develop and maintain schematics, harness drawings, wire lists, splice diagrams, and connector face views using the Zuken E3 suite</li> <li data-uuid="a24556b4-3995-41b5-8ed9-6f5ec30d4ef1">Drive design-to-manufacturing through Zuken E3.HarnessBuilder, using automation to move cleanly from design intent to manufacturing outputs</li> <li data-uuid="540b045c-ba62-4c05-b375-2dea7fad8efd">Define and dimension controlled harness lengths, branch and breakout tolerances, and service-loop allowances on 2D drawings</li> <li data-uuid="fc9265ab-25ef-4961-895f-74c1f3a4e763">Define routing intent, grounding and bonding strategy, and shielding architecture across LV, HV, and RF interconnects within tightly constrained spacecraft volumes</li> <li data-uuid="b19eb809-eb34-416f-afc5-0c776202592c">Audit wire diagrams and harness topologies for accuracy against interface control documents (ICDs)</li> <li data-uuid="f9b62140-829f-4e73-b78b-39883df10063">Specify physical protection and support for harnesses, including lacing, tying, convolute, and thermal/abrasion protection appropriate to the space environment.</li> <li data-uuid="496f1428-932c-4d9b-bc0f-25ac3401bab6">Build, modify, and validate prototype and test harnesses</li> <li data-uuid="40d3ad47-37b0-4b6e-b1ec-b6d6185077bc">Support pre-launch integration and test operations on the ground, including on-vehicle harness routing, installation, and connection</li> <li data-uuid="1942bdd1-daf4-4721-a240-39eb4391f31e">Partner across subsystems (avionics, power, propulsion, payload) and functions (production, environmental test, and vehicle test), since the harness interfaces with nearly every part of the spacecraft</li> <li data-uuid="1de198ad-3d7c-4cbe-b582-c071bbbc928b">Lead root-cause analysis and implement design improvements that enhance reliability, manufacturability, and serviceability</li> <li data-uuid="33dca06c-bafd-4ef4-9e42-931a0df41870">Collaborate with manufacturing and harness suppliers on DFM/DFI feedback, assembly documentation, and process validation</li> </ul> <h4 id="JobDescriptionSeniorHarnessDesignEngineerI/II-Whatyou'llNeed(Requirments)">What you'll Need (Requirements)</h4> <p><em>We think about this role as one discipline of depth and one of literacy: electrical design is the proficiency, mechanical is the literacy.
