Database Engineer

About Mecka AI

Mecka AI is building the data infrastructure layer for robotics and embodied AI.
We design and operate global systems for data capture, data labeling, and hardware-enabled workflows used by leading AI labs and robotics companies to train and validate humanoid and embodied AI systems.
We work closely with frontier robotics teams to bridge real-world data, simulation, learning-based systems, and deployed hardware.

About the role

Our database layer sits under everything Mecka ships, and it's growing quickly. We're looking for someone to own it: learn what we've built, set the plan for where it goes next, and help us scale.

As part of our Platform Engineering & Infrastructure team, you'll work hands-on with MongoDB and ClickHouse at scale and take on challenges no one has solved for us yet. We need someone who brings both speed and quality, and who wants real ownership.

What you'll do

• Own the database layer: Take full ownership of Mecka's MongoDB and ClickHouse, and make the decisions that keep them healthy.

• Learn it, then own it: Get a real grasp of the current setup in your first months, including a short overlap with a MongoDB engineer on contract, and take it from there.

• Design the schema path: Come in with a medium- and long-term plan for schema and database design.

• Plan the scale-up: Map out what 2x to 10x data growth looks like, and how we avoid outages without a ton of compute and cost.

• Solve what's new: Take on the unique problems that come with scaling, and find the path forward quickly without cutting corners.

What you'll need

• 3+ years owning databases in a growing, fast-paced environment.

• Expert in MongoDB and ClickHouse, including advanced features at scale.

• You've scaled databases through rapid growth before, and you bring those lessons with you.

• You can ramp up, and you're ready to own the database layer.

• You move quickly, and you have a point of view on how we should scale, avoid outages and keep this sustainable.
