Role
Who you are
- This role is ideal for engineers who care deeply about understanding customer needs, enjoy working directly with product and design, and want to build tools for sophisticated technical users
- 6+ years of professional software engineering experience
- Strong experience with JavaScript/TypeScript and modern frontend frameworks (e.g., React)
- Experience building backend systems in Python, Go, or similar languages
- Demonstrated ability to ship full-stack features end-to-end
- Product-minded: you seek to understand the “why,” not just implement tickets
- Comfortable working in ambiguity and collaborating closely with cross-functional teams
- Must be a US citizen living within the United States
Desirable
- Experience building developer tools or technical user-facing products
- Experience integrating AI into software products (LLMs, embeddings, AI-assisted workflows)
- Background in aerospace, defense, digital engineering, or other regulated domains
- Experience with secure or air-gapped environments
What the job involves
- We’re looking for a full-stack, senior engineer to join our team building modern web applications, developer tools, and AI-powered workflows for aerospace and defense customers
- This team sits closest to the user. We build the interfaces, APIs, and intelligent tooling that engineers rely on to do mission-critical work. You’ll work across the stack — from React and TypeScript on the frontend to Python and Go services on the backend — delivering secure, high-performance systems in complex environments
- Build Across the Stack: Develop modern frontend applications using TypeScript and React. Design and implement backend services in Python and Go. Build clean, well-tested APIs that power complex engineering workflows. Contribute to system architecture with an eye toward scalability, reliability, and security
- Solve Real Customer Problems: Engage directly with product managers, designers, and occasionally customers to understand real-world workflows. Translate ambiguous user needs into thoughtful technical solutions. Iterate quickly, validate assumptions, and refine features based on feedback
- Improve Developer & AI Tooling: Build internal and customer-facing developer tools, SDKs, and workflow automation systems. Integrate AI capabilities (LLMs, retrieval systems, copilots) into product experiences. Help improve CI/CD, local development environments, and engineering productivity
- Operate in Mission-Critical Environments: Build systems that function reliably in secure, regulated, or air-gapped settings. Balance speed with correctness, performance, and long-term maintainability
Our take
In the realm of digital engineering, industries like aerospace, defense, and manufacturing face significant challenges. Traditional methods of designing, testing, and certifying complex systems are often time-consuming, costly, and environmentally taxing. These processes typically require physical prototypes and extensive real-world testing, leading to delays and increased resource consumption.
Istari is transforming this landscape by developing a platform that enables the creation, testing, and certification of technologies entirely in the digital real. Its advanced digital twin technology allows for virtual simulations and modeling, reducing the need for physical prototypes. This approach not only accelerates development timelines but also minimizes costs and environmental impact.
Its making major progress too, including the $19M contract with the US Air Force to help develop the world's first digitally certified aircraft. While the use of digital twins in military applications (especially with potential links to autonomous systems) can raise valid ethical concerns, Istari's focus is on safety, precision, and reducing the need for real-world testing that can be risky or wasteful. By improving how complex systems are designed and certified, its aiming to make engineering across industries more efficient and sustainable.
