Software Engineer/IT

TIBERIUS AEROSPACE Senior Software Engineer Internal Platforms & Corporate Technology Location: Remote — United States Employment Type: Full-Time Department: Engineering Reports To: Chief Technology Officer Travel: Occasional Citizenship Requirement: U.S. Citizen Primary Technologies: Go, Rust, Kubernetes, Nix/NixOS Pay Scale: $175K to $250K About Tiberius Aerospace Tiberius Aerospace is building the next generation of weapons systems for the United States, United Kingdom, and their allies. We believe the future of defense will be built differently: through faster iteration, tighter integration of software and hardware, and a modern approach to how mission-critical systems are designed, tested, deployed, and continuously improved. Our systems do not stop evolving once they leave the factory. Tiberius is building technologies—and a defense ecosystem—that connect engineers, operators, manufacturers, governments, and allies into a continuously learning system. To serve our nations with Strength, Honor, and Purpose — forging the systems that defend freedom and shape the future of defense. The Role Tiberius is seeking a Senior Software Engineer to build and operate the internal systems that keep the company moving. This is a multidimensional engineering role for someone comfortable moving across software development, platform engineering, infrastructure, developer tooling, and corporate technology. You will build internal tools, automate operational workflows, improve developer productivity, and solve the technical problems standing between the team and the mission. You will report directly to the CTO and operate in small, high-trust teams with significant autonomy. We value engineers who finish what they start, take pride in what they ship, and are willing to take on the work that matters—whether it is a production service, Kubernetes cluster, CI pipeline, identity system, endpoint issue, or internal tool that removes friction for the entire company. This is a fully remote U.S. role . The successful candidate may remain remote on an ongoing basis, with occasional travel for company meetings, planning sessions, technical work, or other business needs. What You’ll Do Design, build, and maintain internal software and tooling used across Tiberius. Develop services, automation, and operational tools primarily in Go and Rust . Build, operate, and continuously improve infrastructure running on Kubernetes . Create reproducible development and system environments using Nix and NixOS . Improve developer workflows, CI/CD, infrastructure management, deployment practices, and system reliability. Automate corporate IT and operational processes wherever practical. Support internal technology across applications, Linux systems, networking, identity, endpoints, and SaaS platforms. Investigate and resolve ambiguous technical problems without waiting for them to become someone else’s ticket. Partner with engineering, security, operations, and business teams to remove blockers and deliver complete outcomes. Build systems that are reliable, tested, documented, secure, and maintainable. Mentor other engineers and help shape technical direction as the company grows. What You’ll Bring Significant professional software engineering experience, including operating at a Senior Software Engineer level. Strong software-development experience with Go . Experience developing systems, services, or tooling with Rust . Strong practical Kubernetes experience, including deploying, operating, and troubleshooting containerized workloads. Experience with Nix and/or NixOS for reproducible environments, system configuration, or package management. Strong Linux and systems-engineering fundamentals. Experience designing and maintaining production-quality internal tools, infrastructure, or platform services. Solid understanding of networking, APIs, authentication, and distributed-systems fundamentals. Ability to independently investigate unfamiliar systems and carry ambiguous technical problems through to resolution. Strong written and verbal communication skills. Ability to work effectively in a remote, highly collaborative environment. Preferred Experience Experience in several of the following areas is valuable: Platform engineering and developer experience Infrastructure as Code CI/CD, build systems, and release automation Cloud infrastructure Identity and access management SSO, SAML, OAuth, and OpenID Connect Corporate-device and endpoint management Networking and VPN technologies Observability, logging, and monitoring Secrets management Security engineering GitOps IT automation and SaaS administration Zero-trust architecture You do not need to be an expert in every area. We value engineers with strong fundamentals, sound judgment, a fast learning curve, and the willingness to take ownership beyond the boundaries of a conventional job description. What We’re Looking For You get after the mission. You understand that speed matters. You look for ways to remove unnecessary steps and friction without lowering the quality bar. You own the outcome. You do not stop at identifying a problem, producing a status update, or handing unfinished work downstream. You carry things across the line. You do work you’re proud of. You test assumptions, fix problems properly, and build systems you would be comfortable handing to the sharpest engineer you know. You pick up the broom. Titles do not determine what work is worth doing. If running a cable, writing documentation, debugging another team’s service, or resolving an IT issue moves the mission forward, you do it. You seek criticism. You want candid technical feedback. You change your mind when the evidence changes, and care more about getting the answer right than being right. You are a doer. You prototype, build, fix, and close loops. When you see something broken, your instinct is to make it better. Above all, we
