Senior Full Stack Engineer

Position Overview:

As a Senior Full Stack Engineer at Inversion, you will define and build the internal software tools that help our engineering teams innovate, make better decisions, and operate more effectively. You will own the development of internal applications across the stack, from intuitive user interfaces to backend services and integrations. This role is cross-functional and ambiguous by design: you will identify high-leverage opportunities, work closely with technical users, and help shape what high-quality internal tools should look like at Inversion.

Key Responsibilities:

• Design, build, and maintain internal web applications and tooling that support engineering workflows across the company.
• Own the end-to-end lifecycle of internal tools, including problem definition, technical design, implementation, testing, deployment, and long-term maintenance.
• Build intuitive user interfaces and workflows for technical users, with a strong focus on usability, clarity, and speed.
• Develop backend services, APIs, and integrations that support internal dashboards, documentation systems, data review tools, and AI-enabled workflows.
• Partner closely with engineers and other technical stakeholders to identify pain points, gather requirements, and translate loosely defined needs into practical internal products.
• Help define best practices for internal application development, including architecture, testing, code quality, and maintainability.
• Contribute to the long-term product and technical direction of the Internal Software Tools team.

Required Qualifications:

• Typically 5+ years of professional software engineering experience building and shipping production-quality software systems.
• Strong front-end development experience with TypeScript/Javascript and frameworks like React.
• Experience developing backend systems, APIs, or internal tools using technologies such as Python, Node.js, or Go.
• Strong software engineering fundamentals, including system design, testing, debugging, code quality, and maintainability.
• Familiarity with Linux development environments and basic CI/CD workflows.
• An innovative and optimistic approach to an environment with high ambiguity, shifting priorities, and loosely defined problem spaces.
• Position may require occasional extended hours and/or weekend work.
• Must have the ability to obtain and maintain a U.S. government Secret/Top Secret security clearance. 

Desired Qualifications:

• Experience building internal tools for engineering teams, such as dashboards, test and data review tools, documentation systems, or workflow automation. Extra points if this was for Aerospace!
• Experience integrating AI-enabled capabilities or interfaces into internal software products.
• Familiarity with databases, data modeling, and the tradeoffs between different storage approaches.
• Familiarity with Docker, Kubernetes, or modern deployment workflows.
• Prior experience in a small team or startup environment where you were expected to define scope, set direction, and execute with a high degree of ownership.
