This role sits at the intersection of product thinking and full-stack engineering — you'll own complex user experiences end-to-end, from shaping the problem through shipping polished, performant interfaces backed by robust services. The ideal candidate is frontend-forward but comfortable across the entire stack, from desktop applications to web frontends to backend services. You think in terms of user outcomes, not just technical implementation, and you're energized — not paralyzed — by ambiguity and unknowns. Core Responsibilities: - Own complex features from problem definition through delivery, shaping scope, navigating unknowns, and making tradeoffs across the product lifecycle. - Design and build rich, performant user experiences for identity, security, secure content sharing, resource management, and data access workflows across the platform. - Thread together complex multi-step user flows that feel coherent and intuitive, even when the underlying systems are deeply technical. - Build and maintain the frontend and backend services that power these experiences, working across desktop applications, web frontends, APIs, and backend services. - Apply a security-minded approach to frontend and full-stack work — understanding how authentication flows, authorization boundaries, and data classification translate into safe, trustworthy user experiences. - Champion frontend performance — bundle size, render efficiency, perceived speed, responsiveness — as a first-class engineering concern. - Embrace and leverage modern development workflows, including AI-assisted tooling, to accelerate iteration and raise the quality bar across the team. - Contribute to building a data studio experience that surfaces platform data to users in powerful, intuitive ways. - Partner with platform, integrations, and infra teams to ensure identity and security primitives are reflected in clear, usable interfaces. - Participate in design reviews and contribute to technical direction, bringing a strong product and UX sensibility to architectural discussions. - Write high-quality, well-tested code with an eye toward reliability, accessibility, and performance. Required Qualifications - 8+ years of professional software engineering experience, with significant depth in frontend and full-stack product engineering. - Strong proficiency in modern frontend frameworks (React, TypeScript) with deep understanding of frontend performance optimization — rendering, state management, bundle efficiency, and perceived performance. - Comfortable and effective across the full stack — you can build a polished UI and then wire it to the backend service that powers it. - Experience with Go and/or Python for backend services; willingness to work in both. - Fluency with modern developer tooling and AI-assisted workflows — you actively use these tools to move faster and think bigger, not just to autocomplete. - Proven ability to take large, ambiguous chunks of scope and break them into shippable increments — you're comfortable being the person who figures out "what are we actually building" before writing code. - Experience building UIs for complex, security-sensitive domains like identity, access control, permissions, or data classification is a strong plus — you understand how to present security concepts to users without compromising the underlying guarantees. - Experience with desktop application development (Electron or similar) is a plus. - Strong product instinct — you think about the user's mental model, not just the data model. - Excellent communication skills and ability to collaborate cross-functionally with design, product, platform, and infrastructure teams. - Bachelor's degree in Computer Science, Engineering, or related field, or equivalent professional experience. - Must be a US citizen or permanent resident living within the United States. We've built a team of what we call Wizards -- people who bring depth in their domain and range across others, who are collaborative without being deferential, and who genuinely care about what we're building. We celebrate individual contributions, give feedback early and often, and argue about ideas so we can execute together. There's no room here for hierarchy for its own sake, or for busywork that doesn't move the mission. We are outcomes-driven, and we hold each other to a high standard — with genuine respect for each person's expertise and wellbeing. Focus is rewarded.  Finish is remembered. Facts are friendly.  Even when they are not fun. Fellowship is fundamental.  Make others successful. ## About Istari Digital ## Company Overview - **One-liner**: Istari Digital provides a digital engineering infrastructure platform that connects and validates engineering data across fragmented environments for mission-critical industries like aerospace, defense, and energy. - **Entity Type**: Private (Series A‑II; venture-backed) - **Headquarters**: Arlington, Virginia, United States - **Founded**: 2022 - **Founders**: Dr. Will Roper (CEO) and Christopher Benson (CTO) ## Core Business - **Primary industries**: Aerospace, defense, space, energy, transportation, critical infrastructure - **Target customers**: Enterprise and government organizations in “no‑fail” sectors (e.g., Lockheed Martin, Blue Origin) - **Mission**: “Level the digital playing field in no‑fail industries” – enabling secure, auditable, and AI‑native engineering workflows without centralizing sensitive data ## Products & Services - **[Istari Digital Platform](https://www.istaridigital.com/product)**: A digital infrastructure that securely routes engineering data across tools, teams, and classification boundaries. It connects models, simulations, and workflows to enable real‑time collaboration, system validation, and compliance certification – all while keeping data under the owner’s control. (Type: SaaS / Platform) ## Market Standing - **Valuation**: Not publicly disclosed - **Key Metric**: Total funding – $55.05M (per CBInsights) or $40.1M (per LinkedIn); conflicting reports may reflect different round definitions - **Notable Investors**: Icon Ventures, Teamworthy Ventures, Eric Schmidt, AeroX Ventures, Radius Capital - **Growth Signals**: - Headcount of 64 employees (+61.5% year‑over-year) - LinkedIn followers grew 48.1% in the past year - Acquired Istari Federal LLC and Dgraph (2025) - Customers include Lockheed Martin and Blue Origin - 27 patents filed (as of early 2025) ## Competitive Advantages - **Built for no‑fail industries**: The platform is designed for environments where failure is not an option (fighter jets, satellites, critical infrastructure), giving it a deep credibility moat. - **Secure collaboration without compromise**: Enables cross‑organization, cross‑classification collaboration while allowing each party to retain control of their own data – a key differentiator in defense and regulated sectors. - **Agentic engineering & AI‑native workflows**: Integrates AI into engineering validation and certification, reducing cycles from months to minutes. - **Founders with domain expertise**: CEO Will Roper was the former Assistant Secretary of the Air Force for Acquisition, Technology and Logistics; CTO Christopher Benson brings deep technical experience from hyperscalers and defense programs. ## Strategic Focus - Scaling the platform to serve more mission‑critical industries (air, sea, space, energy, transportation) - Deepening AI capabilities for automated validation, compliance, and certification - Expanding through acquisitions (Istari Federal, Dgraph) to strengthen federal presence and graph‑based data capabilities - Building a distributed workforce with offices in Arlington (HQ), Cambridge (MA), and remote roles across the US ## Why Work Here - **Mission‑driven culture**: Employees work on genuinely hard, unsolved problems in decentralized data sovereignty, AI engineering, and cross‑domain security – with direct impact on national security and critical infrastructure. - **Remote‑friendly**: Many roles are listed as remote (anywhere US) or hybrid (DMV area); on‑site options exist in Huntsville, AL and Seattle, WA. - **Diverse team background**: The team comes from defense, industry, academia, government, and startups – “everyone’s background is a feature, not a footnote.” - **Growth trajectory**: Rapid headcount growth, recent acquisitions, and strong investor backing suggest a high‑growth environment with ample career development opportunities. - **Engineering culture**: Emphasis on deep curiosity, craft, and solving problems that matter; the platform is built by people who have lived the pain of manual, siloed engineering workflows. ## Sources 1.
