Onsite Technical Delivery

• Embed with customer engineering teams to understand their workflows, data environments, and technical constraints

• Architect and build software solutions that integrate Istari's platform into existing digital engineering ecosystems (CAD, CFD, FEM, simulation pipelines, and related toolchains)

• Serve as the primary technical interface for the customer – not just answering questions, but proactively identifying where our software can drive more value

Software Development

• Develop, test, and maintain integrations and workflow solutions following modern software engineering practices

• Write clean, maintainable code that can be productized or reused across customer deployments

• Contribute to internal tooling and documentation that scales your knowledge across the team

Feedback Loop to Product

• Translate field experience into actionable product insights — you are one of Istari's clearest signals on what customers actually need

• Participate in internal engineering reviews, architecture discussions, and roadmap planning

• Help develop proposals and technical approaches for new customer opportunities

Required

• Strong software engineering fundamentals — you write production-quality code and can defend your architectural decisions

• Hands-on experience with digital engineering toolchains: CAD, CFD, FEM, or related simulation and modeling environments

• Comfort operating in ambiguous, fast-moving environments without a lot of hand-holding

• Ability to work on-site with customers in a U.S. defense or aerospace context (clearance eligibility required; active clearance a strong plus)

• U.S. citizenship required

Preferred

• Experience integrating engineering software into larger data or workflow platforms

• Background in aerospace, defense, or other systems-engineering-heavy industries

• Exposure to Model-Based Systems Engineering (MBSE) or digital thread / digital twin concepts

• Exposure to or direct experience with advanced CAD, CFD, or FEM tools

The engineers who do this job well become some of the most technically well-rounded people in the industry. You'll see how large, complex organizations actually work — not just the happy path. You'll build things that get used immediately. And because you're reporting into Istari's Customer Success org (not a sales or account team), your career trajectory stays technical.  You'll also have the Istari team behind you: regular syncs, access to internal engineering resources, and a clear path to influence the product you're deploying.

Istari is a digital engineering software company building open, scalable infrastructure for engineering data.
