At eternal.ag, we're building the future of sustainable food production. Our mission is to convert the world's existing greenhouses into fully-autonomous facilities that can produce fresh food year-round - addressing the critical need to double food production by 2050 while facing severe labor shortages, water scarcity, and climate challenges.
We’re looking for a (Senior) Unity XR Developer to build high-fidelity Mixed Reality applications on Meta Quest 3. Your work will power immersive simulations and “wow” demos that make complex greenhouse operations, robotics, and real-time systems understandable at a glance.
You’ll collaborate with a distributed team across Cologne HQ and our Bengaluru office, working closely with robotics, computer vision, and product to bring real systems into XR.
Design and develop immersive XR experiences in Unity for standalone headsets, shipping polished builds that run reliably on-device.
Turn workflows (robots, people/objects, greenhouse layouts, operational events) into intuitive 3D experiences—interactive, explorable, and easy to understand.
Use modern XR stacks (e.g., OpenXR / Meta XR, XR Interaction patterns) to build comfortable navigation, selection/manipulation, UI, and MR passthrough experiences.
Profile, diagnose, and optimize rendering and CPU/GPU performance to hit stable frame rates on Quest (asset budgets, batching, lighting, LODs, shaders, scene structure).
Create reusable systems for scene management, data ingestion, configuration, and debugging so the team can iterate fast without breaking things.
Work with engineers and stakeholders to translate requirements into shippable features, and communicate tradeoffs clearly (quality vs. performance vs. scope).
-
0–5 years professional experience building with Unity + C#
-
Hands-on experience shipping VR/MR applications, ideally on Meta Quest
-
Familiarity with OpenXR / Meta XR SDK and common XR interaction patterns
-
Strong grasp of 3D fundamentals (coordinate systems, transforms, cameras, lighting, basic math)
-
Experience with performance profiling/optimization on device
-
Solid engineering hygiene: Git, debugging, clean code, iterative delivery
-
Experience with URP, custom shaders, VFX, or advanced rendering optimization
-
Familiarity integrating external data sources (e.g., APIs, telemetry, logs, real-time streams)
-
Experience building simulation/visualization tools (digital twins, operational dashboards, 3D mapping)
-
Comfort working with 3D content pipelines (Blender/Maya, asset optimization workflows)
Direct access to experienced founders: Learn directly from founders who've worked at top-tier consulting firms (BCG) and scaled multiple unicorns. You'll gain insights from their experience building world-class companies, not through filtered feedback from middle management.
Real responsibility from day one: Your decisions will matter. Your work will directly impact our trajectory and success.
Unparalleled learning opportunity: Gain exposure to every aspect of building a deep-tech startup - from cutting-edge robotics to international expansion.
Clear growth path: As we scale, you'll have the opportunity to specialize in whatever area excites you most - whether that's leading operations, business development, or even transitioning to a product role.
Competitive compensation: Attractive salary plus meaningful equity that makes you a genuine stakeholder in our success.
International exposure: Work across our Cologne HQ and Bengaluru office, with opportunities to engage with customers and partners globally.
Impact at scale: Your work will directly contribute to solving one of humanity's greatest challenges - sustainably feeding a growing population.
Ready to help build the interface to autonomous food production? Join us in creating immersive XR experiences that make robotics and real-world operations tangible and accelerate the path to fully autonomous greenhouses.
We’re committed to building a diverse and inclusive team. We encourage applications from candidates of all backgrounds. If you’re excited about the mission and can bring strong Unity/XR craft, we’d love to hear from you.
eternal.ag is building fully automated food production sites that can sustainably produce fresh food year-round. Backed by world-class investors and partnering with leading agricultural companies, we're turning the vision of fully-autonomous greenhouses into reality.
