About the Product

We are building a VR training platform that uses generative AI and learning engineering to deliver personalized, hands-on skills training.
 

The product runs immersive training simulations on Meta Quest. A backend service owns the authoritative simulation state and business logic, while the Unity client renders the experience, manages device-side services, and communicates with the backend through defined APIs.

This is a platform engineering role, not a one-off game or simulation project.

The Role

We are looking for a hands-on Senior Unity Engineer to own major parts of the client platform architecture.

You will build reusable Unity infrastructure that supports multiple training simulations and content teams. You will work closely with backend engineers to define API contracts, integrate server-controlled behavior, and ensure that the VR client remains reliable and performant on Meta Quest.

This role is best suited for someone who has built or substantially refactored complex Unity applications and enjoys creating systems that other developers build upon.
 

What You Will Do

• Design and implement reusable Unity client architecture for multiple VR training simulations.
• Build the integration layer between the Unity client and the server, including API contracts, data models, state synchronization, error handling, and recovery behavior.
• Develop device-side services and shared components used across simulations.
• Build Unity Editor tools and workflows for developers and content creators.
• Profile and optimize CPU, GPU, memory, loading, and runtime performance on Meta Quest.
• Establish practical engineering standards for testing, validation, maintainability, and releases.
• Collaborate directly with backend, product, learning, and content-development teams.
• Use AI coding tools where they improve engineering productivity, while maintaining appropriate review and validation standards.
• Make pragmatic technical decisions in an early-stage product environment.
   

Required Experience

• VR development for Android within the last five years, Meta Quest strongly preferred.
• 5 or more years of professional Unity and C# development experience.
• Experience architecting, modernizing, or substantially refactoring a complex Unity codebase.
• Professional experience developing VR applications for Meta Quest.
• Strong understanding of Unity performance optimization for standalone VR hardware.
• Experience designing reusable frameworks, shared services, SDKs, or platform components.
• Experience integrating Unity applications with backend services and structured APIs.
• Strong understanding of software architecture, dependency management, asynchronous programming, error handling, and maintainable C# design.
• Ability to work independently and communicate technical decisions clearly in English.
• English at B2 level or higher.
   

Nice to Have

• Experience with WebGL or additional Unity deployment targets.
• Experience with reactive, event-driven, ECS, or other data-driven architectures.
• Experience building Unity Editor extensions or content-authoring pipelines.
• Experience with automated testing, CI/CD, Addressables, remote content, or release automation.
• Experience with educational technology, simulations, or enterprise training.
   

What Makes This Role Different

• You will build the shared client foundation, not just individual features.
• You will have meaningful ownership of Unity architecture and engineering standards.
• Your work will directly affect multiple simulations, content teams, and future client platforms.
• You will work with a European R&D team on a fully remote schedule.
• European working hours are supported. Regular US-hour work is not required.

We're a 20-person team building a browser-native scientific data platform used by Novartis, J&J, Daiichi-Sankyo, and other top pharma and biotech companies. Our platform was already 10x faster than the competition and delivered more value for less — even before the AI era. Now, we're taking it to the next level.

We're competing with Spotfire, Certara, Dotmatics, and Schrödinger — and winning. How? By building faster and smarter. Our engineering team has fully embraced AI-driven development (Claude Code, agentic workflows, AI-assisted testing), and it's become our biggest force multiplier. We ship in weeks what used to take quarters.

We're looking for an engineering leader who's already living this way — someone who has hands-on experience with agentic development tools and can help lead a team that's pushing the boundaries of what a small, focused group can deliver. You'll report directly to the CEO and have real authority to shape how we build.

What you'll build and lead

This isn't a "manage meetings and write status reports" role. You'll own critical product areas and ship alongside the team. Here's what's on the roadmap:

• AI-powered agentic workflows — Autonomous scientific agents that utilize Datagrok's plugins and integrations as tools.
• Automated testing at scale — Automatic scenarios using Playwright + AI, AI-driven bug reproduction and fixing, stress tests, unit tests, system health tests, plugin tests - everything integrated into CI-CD and managed by AI
• Platform evolution — Cross-application integration and eventing mechanicm, ClickHouse as an analytical backbone, high-performance computations
• Enterprise integrations — Databricks connectivity (ADBC/Arrow for 2–10x speedups), HuggingFace model integration, and dashboard importers for Tableau and Spotfire migrations
• DevOps and infrastructure — ArgoCD deployments, Docker image management, containerized dev environments, and OpenTelemetry observability across a multi-layer stack
• AI-powered knowledge graph — mapping source code, features, tests, docs, and Jira tickets to enable impact analysis and agentic development workflows across the entire codebase
• Process improvements - code reviews, better planning/outcome system, DX improvements, onboarding for new developers

What we're looking for

Must have:

• You've already adopted autonomous agentic development in your own workflow (harnesses, tool-use architectures, AI-driven testing, etc)
• 5+ years as a strong engineer who still codes. This is a hands-on position
• Experience leading a team (formal title matters less than demonstrated leadership)
• Proficiency in TypeScript or Dart; comfort picking up new languages fast. Our core stack is Dart and TypeScript, with C++/WASM, Python, R, Julia, and Matlab in scientific plugins
• Track record of delivering complex software products — not just managing people who do
• You see a problem, you fix it. You don't write a proposal about fixing it. You don't wait for permission
• Strong communication skills and fluent English — you'll work directly with technical clients at pharma companies and present to enterprise IT teams

Strong pluses:

• Life sciences, cheminformatics, or bioinformatics background (or genuine curiosity about this space)
• Experience building agentic AI systems — not just prompting LLMs, but designing autonomous pipelines, harnesses, tool-use architectures, or AI-driven testing frameworks
• Background in high-performance computing, data visualization, or scientific computing
• Startup DNA — you've built things from zero, worn multiple hats, and thrive without a playbook

What we offer

• Real ownership — reporting directly to the CEO, you'll lead critical product areas for a platform deployed at top-10 pharma companies, not maintain someone else's legacy code
• An AI-first engineering culture — we're not "exploring AI adoption." We've already made the transition. You'll help take it further
• Direct client impact — your work will be used daily by scientists doing drug discovery at companies you've heard of
• Startup speed, enterprise clients — the autonomy and pace of a small team, with the validation of Fortune 500 deployments
• Fully remote, zero bureaucracy, flexible hours, unlimited PTO
• Competitive compensation with growth equity opportunity
• Paid training and certifications
