Senior Unity XR Engineer

On behalf of our client, a renowned Athens-based deep tech scale-up that creates award-winning immersive AI/AR/VR experiences to bring cultural heritage to life. They design and deliver award‑winning immersive —blending augmented and virtual reality with advanced AI—to bring archaeological sites, museums and historic landmarks to life for millions of visitors worldwide. Their multidisciplinary teams of engineers, creatives and domain experts collaborate with UNESCO monuments, leading museums and tourism partners to transform complex heritage stories into engaging, data‑driven digital journeys. To strengthen their AI capability, they are recruiting a Senior Unity XR Engineer who can bridges creativity and engineering — ensuring that immersive, real-time experiences built in Unity are not only visually powerful, but scalable, stable, and performant across platforms.

As a Senior Unity XR Engineer, you'll lead the design, architecture, and development of advanced AR and VR applications that merge technology, storytelling, and cultural heritage. You'll take ownership of the technical vision, guiding the evolution of our XR pipeline while mentoring developers and collaborating closely with artists, designers, and AI specialists.

Key Responsibilities

Technical Leadership

• Architect and implement complex XR features and interaction systems using Unity (C#), AR Foundation, OpenXR, and Meta SDKs.
• Define technical standards, performance benchmarks, and reusable frameworks for scalable cross-platform XR development.
• Lead code reviews, guide best practices, and mentor junior engineers in both technical and creative problem-solving.

Development & Optimization

• Develop advanced XR mechanics, UI interactions, and real-time simulation systems.
• Apply 3D mathematics, physics, and matrix transformations to deliver precise spatial interactions and realistic user experiences.
• Profile and optimize rendering, shaders, and performance for mobile and headset devices (Meta, HTC, Apple Vision Pro).

Cross-disciplinary Collaboration

• Work closely with 3D artists, AI developers, UX designers, and archaeologists to translate cultural stories into interactive XR environments.
• Communicate complex technical concepts clearly to non-technical stakeholders — including clients, partners, and cultural institutions.
• Support demos, technical presentations, and integration with third-party systems.

Innovation & Delivery

• Experiment with AI-driven or procedural XR systems that push the boundaries of interactivity and realism.
• Support CI/CD pipelines on Azure, AWS, or GCP, ensuring efficient build automation and versioning.
• Contribute to Agile planning, sprint reviews, and long-term product architecture discussions.

• B.Sc. or M.Sc. in Computer Science, Software Engineering, or a related field.
• 4+ years of professional Unity experience, with at least 3 years in XR (AR/VR/MR) production and 6 XR proven projects.
• Expert knowledge of C#, Unity Engine, and XR frameworks (AR Foundation, XR Interaction Toolkit, OpenXR, Meta SDK).
• Strong applied mathematics: 3D geometry, vector calculus, linear algebra, kinematics.
• Proven track record delivering high-performance XR applications to production.

· Analytical mindset, problem‑solving grit, and the ability to explain complex ideas to both engineers and non‑tech stakeholders.

· Confident English communication skills for demos, technical sales calls and supplier negotiations.

Bonus Points

• Projects combining AI with AR/VR or real-time 3D content.
• Experience with CI/CD pipelines (Azure, AWS, GCP).
• Knowledge of Agile/Scrum collaboration and DevOps workflows.
• Public speaking, blogging, or open-source contributions in the XR/AI community.

• Impact you can see: your models will power real‑world heritage sites and tourist hot-spots, reaching millions every season.
• Creative playground: work alongside archaeologists, historians, XR designers and growth hackers in a flat, agile structure.
• Growth & autonomy: pick the right tools, propose the roadmap and lead from ideation to production.
• Hybrid flexibility: office in Athens + remote days (2 days off-site/3 days on-site)
• Competitive package & benefits: salary that matches your expertise, private health insurance and Ticket meals.
