Requirements:

• Strong backend development experience with C++ (the bulk of the backend is built on a custom in-house framework)
• Hands-on experience with AWS, particularly S3
• Proficiency with Protobuf
• Experience deploying and operating services on Kubernetes, including performance-driven traffic routing to pods
• Performance engineering skills — hash-based routing, SSD-based caching, and memory-mapped files
• Solid systems / low-level fundamentals (there is no off-the-shelf framework to rely on — much of the stack is custom)
• Ability to work highly autonomously and drive work forward with minimal supervision
• Strong communication skills and experience working in distributed teams (Europe/Ukraine time zone; ~1–2 hours of daily overlap with a US-based team)

• Basic DevOps skills

Key Responsibilities:

• Optimize the performance of the C++ data-streaming backend — efficient delivery of large recorded datasets to the browser
• Work on infrastructure-level optimizations: traffic routing to Kubernetes pods, hash-based routing, SSD-based caching, and memory-mapped files
• Operate within a custom data-handling stack — a C++ framework, a custom HTTP server, and a proprietary data format built on top of LevelDB SSTables and Protobuf
• Take ownership of performance work end-to-end, proactively identifying bottlenecks and driving solutions independently
• Collaborate with a primarily US-based team with ~1–2 hours of daily overlap, while working largely independently
• Participate in code reviews and design discussions

About the Project:

You'll join the engineering team of a leading technology company building autonomous mobility and robotics systems. The team develops an internal data visualization platform — a "video and data player" that renders 3D scenes, lidar, and audio recorded by autonomous vehicles. This role sits on the performance work stream: the backend reads on-vehicle data stored in S3, deserializes it from a custom, time-keyed format, and streams it to the browser. The data-transfer service is implemented in C++, and most of the platform's performance gains are expected to come from the backend.

This is a long-term engagement for a strong systems engineer who enjoys low-level performance work and is comfortable ramping on a heavily custom stack with high ownership and minimal supervision.

✅ Ability to work across multiple domains — product, AI, engineering, construction operations, finance, and UX
✅ Strong analytical thinking
✅ Excellent English
✅ Ability to write sharp, detailed product specs
✅ Hands-on mindset — willing to go to construction sites, talk to workers, understand the field, and turn chaos into product logic

Big Advantage:
⭐ Experience with AI agents, computer vision, 3D data, point clouds, LiDAR, drone mapping, BIM/IFC, or digital twins
⭐ Background in construction, infrastructure, real estate development, or field operations
⭐ Experience from OpenSpace, Buildots, Doxel, Autodesk, Procore, DroneDeploy, PlanRadar, Matterport, or similar companies
⭐ Technical background or ability to work closely with engineers without needing everything explained slowly

Who We Need:

A versatile product leader who can think like a product manager, an AI architect, a construction operator, a data analyst, a field manager, and a business owner — all at once.

Someone who can look at a LiDAR scan, a Gantt chart, a construction plan, a workforce report, and a billing sheet — and understand how they all connect.

Your First Mission:

Build the MVP — one floor, one trade, one scan, one schedule, one billing report, one productivity improvement case.
