The Role

About Artefacts / Asteria ART

Robotics is moving fast. The next leap won’t just be better robots—it’ll be better ways to build, test, and validate them before they ever touch the real world.

At Artefacts, we’re developing software tools that bring continuous simulation into robotics workflows and integrate tightly with CI. Our goal is to help robotics teams create an advanced robotized world—more efficient, more reliable, and more environmentally friendly. We also believe emerging AI techniques will reshape how robotics software is designed and produced.

If you’re excited by realistic simulation, interactive 3D environments, and building tools that engineers actually use day-to-day—this role is for you.

About The Role

As a Robotics Simulation Engineer for Asteria ART, you’ll build tools that let robotic engineers simulate and test their robots inside rich, relevant virtual environments. You’ll work side-by-side with the people who will use what you build—so your engineering decisions directly impact simulation quality, iteration speed, and scale.

What You’ll Do

• Create parametric / procedural 3D environments that can be generated, modified, and reused across simulation scenarios.
• Integrate AI-driven workflows to generate simulations or simulation assets from text, images, and other inputs.
• Customize and tune simulation engine performance to support simulation at scale without sacrificing realism.
• Implement custom sensor models so simulated perception matches the behavior engineers expect from real sensors.
• Collaborate closely with robotics engineers to understand their needs and translate them into robust tooling and workflows.
• Iterate quickly: improve simulation fidelity, stability, and developer experience based on real usage and feedback.

What We’re Looking For

We’re looking for engineers who care about realism, tooling quality, and making simulation useful—not just impressive. You’ll thrive if you enjoy building systems that combine 3D, robotics constraints, and software engineering discipline.

Strong fit if you have experience with one or more of the following:

• Programming: Rust, Python, C++ (or equivalent development experience)
• 3D engines & physics simulation: Unreal, Unity, Ogre3D… and physics simulation libraries like Dart, ODE, PhysX
• Parametric 3D modeling: Blender nodes, OpenSCAD… (or similar approaches)
• Generative AI for 3D / CAD: using or building pipelines that create geometry or assets

Nice to have (optional):

• Experience with robotics or robotics simulators
• Experience with Photogrammetry / NeRF
• Experience with cloud computing / high performance computing
• Experience working with GIS data sources
• Experience building generative AI pipelines or training ML models
• Experience with 3D printing
• UI/UX design experience (especially for developer-facing tooling)

The Ideal Candidate

• Has a genuine enthusiasm for realistic simulation software and interactive environments.
• Enjoys tackling hard problems—even when the work is messy and there’s no perfect path upfront.
• Can demonstrate analytical thinking and strong engineering judgment.
• Is comfortable working in a startup environment where priorities evolve and ownership matters.
• Understands the importance of building tools with engineers, not just for them.

Education: A graduate degree can be helpful, but it’s not required to apply. If a work visa is needed, the process can be more difficult without extensive, related work experience.

How We Work Together

Our working conditions are in flux as the team and company grow. We aim to adapt to what works for both the company and the individual—so we encourage you to ask “why” and help shape how things run.

• Inclusive environment
• Personal growth–oriented culture
• Honest salaries (no bonus culture)
• Modern offices within a 5-minute walk from Shinjuku Station (building is a few years old)
• Work style varies: some prefer remote, some office, and some rotate—we gather when needed
• We breathe open source when it makes sense
• Medical checkup support in Tokyo
• We love challenges that help us evolve as a team

Team & Location

• Full-time or part-time as you prefer
• We usually begin with a three-month contract to start working together
• Remote-first team
• Preference for candidates in the JST timezone or similar, and candidates in Japan (especially with hardware experience)

Benefits

• Flexible work arrangement (remote-first, office when needed)
• Support for medical checkups in Tokyo
• Modern Shinjuku office access
• Personal growth and ownership in a small team
• Stable, transparent compensation (no bonus culture)

Application Process

We want applying to be a good experience for you, and we respect your time. The best way for us to decide working together is to get to know each other—starting with what we share publicly online.

Typical application flow:

1. Apply by sending your resume and cover letter (we strongly value public contributions).
2. First online meeting, or explain why we may not meet at this time.
3. Additional meetings may be arranged to help both sides understand the fit (sometimes on site).
4. We aim to make decisions relatively quickly.
5. We may ask for references.

To help us assess fit, please include:

• Publicly visible work such as open source contributions, personal blogs, Medium posts, or published papers
• Public accounts like GitHub, StackExchange, etc.
• Presentations at meetups or conferences
• Projects you’re particularly proud of and why

Important: Please mention the word SURVIVOR and tag RMmEwMjpjMjA3OjIzMjA6MjI2ODo6MQ== when applying to show you read the job post completely (#RMmEwMjpjMjA3OjIzMjA6MjI2ODo6MQ==). This beta feature helps us avoid spam applicants.
