Company mission
To make digital engineering ecosystems a reality where all technologies are created digitally, free from real-world costs, schedules, and environmental impacts.
Role
Who you are
- This role requires strong architectural judgment, hands-on technical leadership, and the ability to collaborate cross-functionally to deliver extensible platform capabilities that support both traditional integrations and AI-driven use cases
- 5+ years of professional software engineering experience, with at least 2 years in senior roles
- Proven experience building scalable, reliable, and secure distributed systems, including systems that integrate AI/ML capabilities
- Experience integrating AI-powered features into production systems, with an understanding of performance, reliability, and governance considerations
- Deep expertise in REST API design and implementation
- Experience designing and operating event-driven architectures
- Strong coding skills across multiple layers of the stack (backend services, SDKs, developer tooling, and AI-integrated systems)
- Strong understanding of microservices architecture and domain-driven design
- Strong proficiency in Python (object-oriented and functional programming)
- Experience with Golang and TypeScript
- Track record of technical leadership, mentorship, and cross-functional collaboration
- Excellent communication skills with the ability to influence at both technical and strategic levels
What the job involves
- We are seeking a highly experienced Senior Software Engineer to join our Core Platform team
- In this role, you will own and evolve the end-to-end architecture of the Core Platform, including backend services, SDKs, AI-enabled capabilities, and supporting infrastructure
- You will design and operate scalable APIs, event-driven systems, distributed services, and AI-integrated workflows, ensuring high standards for reliability, performance, observability, and security
- You will help set technical direction, mentor engineers, and drive engineering best practices across the team
- Own the end-to-end architecture of the Core Platform, including backend services, SDKs, AI-enabled components, and related infrastructure
- Design and implement scalable APIs, event-driven systems, distributed services, and AI-integrated capabilities (including AI/ML and MCP integrations)
- Architect systems that reliably incorporate AI models into production environments, with strong attention to observability, latency, cost management, and failure handling
- Lead API design and implementation with a focus on usability, performance, and long-term maintainability
- Architect and evolve microservices using domain-driven design principles
- Build platform abstractions and primitives that enable AI-driven workflows and agent-based capabilities
- Partner closely with Product, Infra, and Customer Success teams to deliver seamless, customer-centric integration capabilities
- Provide technical leadership, mentorship, and architectural guidance to engineers
- Establish and elevate engineering best practices across design, development, testing, and operations
Our take
In the realm of digital engineering, industries like aerospace, defense, and manufacturing face significant challenges. Traditional methods lof designing, testing, and certifiying complex systems are often time-consuming, costly, and environmentally tacxing. 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 aplatform 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 minimized 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 certifies, its aiming to make engineering across industries more efficient and sustainable.
