Senior Software Engineer (Back-end)

<div class="content-intro"><p><strong>Turning Space into a Transportation Layer for Earth</strong></p></div><h3>Who We Are:</h3> <p>Inversion builds advanced reentry systems to deliver next-generation capabilities from space.<br>&nbsp;<br>Our mission is to make Earth radically more accessible by turning Low-Earth Orbit into an on-demand logistics domain. We see space not as a destination, but as a platform — one that unlocks unprecedented speed and global reach.<br>&nbsp;<br>Our spacecraft are designed to deliver payloads anywhere on Earth in under an hour, operating through extreme reentry conditions and landing with high precision. These systems open the door to new ways of testing, delivering, and operating at hypersonic speeds.<br>&nbsp;<br>Inherently dual-use, our technology is built to meet urgent national security needs while laying the groundwork for future commercial applications. Backed by leading investors including Y Combinator, Spark Capital, and Lockheed Martin Ventures, and working with partners such as the U.S. Space Force and NASA, Inversion is pushing the boundaries of what’s possible in space-based defense and logistics.</p> <h3 id="About-the-Role" data-renderer-start-pos="686">About the Role</h3> <p data-renderer-start-pos="702">As a Senior Back-end Engineer at Inversion, you will work as part of the simulation team to design, develop, and maintain the architecture and server-side logic of the applications that support the simulation and test environments for our flight systems. The simulation team is responsible for ensuring that flight software and flight hardware can be continuously integrated and tested under realistic flight conditions. You will play a key role in the design and development of data management and self-service tools that will enable fast, repeatable development and deployment workflows across the engineering stack. Your work will empower Inversion’s engineering teams to iterate rapidly throughout the development life cycle and will strengthen Inversion’s ability to put our products into the hands of our customers with unprecedented speed and agility.</p> <h3 id="What-You'll-Do" data-renderer-start-pos="1555">What You'll Do</h3> <ul> <li data-renderer-start-pos="1573">Design, deploy, and maintain the server-side logic and infrastructure of the applications that support simulation workflows, including <strong data-renderer-mark="true">high-performance computing (HPC)</strong>, <strong data-renderer-mark="true">software-in-the-loop (<span data-highlighted="true" data-vc="highlighted-text"><span class="_kqswh2mm"><span class="_5pioz8co _189eyh40 _1il9buyh _19lcevot _d0altlke" data-testid="definition-highlighter">SIL</span></span></span>) testing</strong>, and <strong data-renderer-mark="true">hardware-in-the-loop (<span data-highlighted="true" data-vc="highlighted-text"><span class="_kqswh2mm"><span class="_5pioz8co _189eyh40 _1il9buyh _19lcevot _d0altlke" data-testid="definition-highlighter">HIL</span></span></span>) testing</strong></li> <li data-renderer-start-pos="1820">Select a <strong data-renderer-mark="true">back-end tech stack</strong> that ensures the performance and scalability of our applications</li> <li data-renderer-start-pos="1917">Design and implement a <strong data-renderer-mark="true">back-end architecture</strong> that strikes the right balance between simplicity and flexibility</li> <li data-renderer-start-pos="2031">Design and develop <strong data-renderer-mark="true">databases architectures</strong> and <strong data-renderer-mark="true">data pipelines</strong> to meet <strong data-renderer-mark="true">configuration and data management</strong> needs</li> <li data-renderer-start-pos="2144">Leverage self-documenting API tools and technologies to develop robust and efficient <strong data-renderer-mark="true">APIs</strong></li> <li data-renderer-start-pos="2237">Leverage modern <strong data-renderer-mark="true">web frameworks</strong> to develop <strong data-renderer-mark="true">server-side logic</strong></li> <li data-renderer-start-pos="2300">Work with front-end engineers to <strong data-renderer-mark="true">integrate</strong> the front-end with the back-end and <strong data-renderer-mark="true">deliver</strong> a smooth <strong data-renderer-mark="true">user experience (UX)</strong></li> <li data-renderer-start-pos="2422">Contribute to the design and development of a simulation system capable of <strong data-renderer-mark="true">automatically provisioning and deploying</strong> resources to support simulation workflows</li> </ul> <h3 id="Required-Qualifications" data-renderer-start-pos="2583">Required Qualifications</h3> <p data-renderer-start-pos="2608">Candidates must meet all of the following qualifications to be considered for this position:</p> <ul> <li data-renderer-start-pos="2704">6+ years of professional experience in <strong data-renderer-mark="true">back-end or full-stack development</strong></li> <li data-renderer-start-pos="2781">Expertise in <strong data-renderer-mark="true">back-end engineering</strong> and best practices</li> <li data-renderer-start-pos="2839">Proficiency in one or more <strong data-renderer-mark="true">scripting languages </strong>(Python, Lua, Bash, PowerShell, etc.)</li> <li data-renderer-start-pos="2929">Experience with <strong data-renderer-mark="true">Linux-based systems</strong></li> <li data-renderer-start-pos="2968">Experience with modern <strong data-renderer-mark="true">DevOps</strong> practices</li> <li data-renderer-start-pos="3011">Experience with one or more <strong data-renderer-mark="true">back-end architectures</strong> (monolithic, modular, serverless, event-based, microservices, etc.)</li> <li data-renderer-start-pos="3133">Experience with one or more <strong data-renderer-mark="true">API architectures</strong> (REST, GraphQL, gRPC, WebSockets, Webhooks, etc.)</li> <li data-renderer-start-pos="3232">Experience with one or more <strong data-renderer-mark="true">database systems </strong>(<span data-highlighted="true" data-vc="highlighted-text"><span class="_kqswh2mm"><span class="_5pioz8co _189eyh40 _1il9buyh _19lcevot _d0altlke" data-testid="definition-highlighter">MySQL</span></span></span>, Oracle, MongoDB, DynamoDB,&nbsp;
