About the client

Our client is developing technology to make industrial environments safer and reduce the risk of accidents through proactive monitoring.

The Ukrainian engineering team is building a next-generation industrial safety platform combining Computer Vision, Machine Learning and IoT.

About the role

We are looking for a Middle Systems / Software Engineer to work on the performance-critical core of a real-time Computer Vision platform.

This is not a typical Python Backend role. The main challenge is building and optimising the systems underneath the CV/ML engines — where performance depends on memory, processes, concurrency, data movement, CPU/GPU utilisation and low latency.

You will work on the runtime that executes CV pipelines as a graph of processing stages, with latency measured in milliseconds. You will deal with shared memory, zero-copy data transfer, inter-process communication and process orchestration.

What matters most to us

We are open to engineers coming from C++, Python, Go or similar backgrounds.

The programming language itself is not the main selection criterion. What matters much more is a strong systems engineering mindset and experience understanding what is happening inside a system.

For example, we are particularly interested in engineers who have worked with problems such as:

• reducing unnecessary memory copies;
• optimising CPU/GPU utilisation;
• investigating latency spikes and performance bottlenecks;
• working with processes, threads and concurrency;
• debugging race conditions and difficult low-level issues;
• profiling applications and identifying bottlenecks;
• designing efficient data-processing pipelines;
• working with large amounts of data moving through several processing stages;

• optimising algorithms or runtimes for performance.

   

A candidate does not necessarily need to have worked with exactly the same technologies before.

For example, experience with CUDA, C++, GPU optimisation, real-time processing, robotics, computer vision, video pipelines, scientific computing or other performance-sensitive systems can be highly relevant.

What you’ll work on

• Collaborate with CV/ML engineers to turn model inference code into reliable production pipeline stages.
• Develop and optimise the core Pipeline Engine — an in-process, real-time runtime executing the CV pipeline as a graph of stages.
• Work with zero-copy shared-memory pools for passing frames between processes.
• Develop and optimise low-latency ZeroMQ communication for control messages, metadata and synchronisation.
• Work with pipeline metadata and serialisation boundaries.
• Analyse and improve CPU, memory and latency performance.
• Profile, debug and troubleshoot complex runtime issues.

• Contribute to the architecture and evolution of the real-time processing infrastructure.

   

Requirements

Must-have

• Commercial experience as a Software Engineer / Systems Engineer / C++ Engineer / Python Engineer or similar.
• Strong systems engineering mindset and understanding of:
  • processes and concurrency;
  • memory ownership and data movement;
  • latency vs throughput trade-offs;
  • performance bottlenecks;
  • profiling and debugging;
  • failure modes of complex systems.
• Experience working with performance-sensitive or latency-sensitive systems.
• Experience with at least one of C++, Python, Go or a similar programming language.
• Python is used in the platform, but it does not need to be your primary language. Strong C++ / systems experience is equally relevant.
• Solid Linux fundamentals.

• Solid experience with Docker and containerised environments.

   

Nice-to-have

• CUDA, including IPC handles and stream synchronisation.
• C/C++ or Go.
• OpenCV.
• GStreamer, FFmpeg or RTSP.
• ZeroMQ.
• Shared memory / zero-copy architectures.
• FlatBuffers or other binary serialisation formats.
• Experience building or operating camera/video pipelines.

What we offer

• Competitive compensation.
• Benefits package.
• Strong engineering team.
• Opportunity to work on challenging real-time Computer Vision infrastructure.
• Meaningful industrial safety use case.
• Technical challenges and opportunities for professional growth.

We are looking for a Senior Backend Engineer to help scale a high-throughput, real-time bidding
platform that sits at the core of our header-bidding and identity products. You will design and
operate Go services that handle very high request volumes with tight latency budgets, working
close to the auction path where milliseconds and correctness both matter.
This is a hands-on engineering role on a fast-growing product. You will own services end to end
— from design and implementation through deployment, observability, and on-call — and
collaborate with product, QA, and business-development colleagues to ship integrations with ad-
tech partners and demand/supply platforms.

Key Requirements:

🔹Strong, production-level experience writing backend services in Go (Golang), including the concurrency model, profiling, and performance tuning (7+ years of commercial Go experience required).
🔹Demonstrable experience with header bidding — ideally hands-on with Prebid (Prebid Server adapters, modules, RTB, or comparable auction-side work).
🔹Experience building and operating high-throughput, low-latency distributed systems in production (must-have).

🔹Solid grasp of HTTP/REST, JSON, and server-to-server integration patterns, plus debugging across the request lifecycle.
🔹Strong experience with cloud infrastructure, primarily AWS (must-have). Experience with Azure and/or GCP is a strong advantage.
🔹Comfort with relational databases (e.g. MySQL / Aurora), including basic observability and deployment workflows.
🔹Pragmatic testing habits and a track record of shipping reliable software with good operational hygiene.
🔹Strong debugging and problem-solving abilities.
🔹Experience with CTV/video and post-bid measurement flows.
🔹Exposure to Prebid Server Java or other JVM services (useful for cross-module work).
🔹Experience with Kafka/streaming, Redis or similar caching layers, and container orchestration (Docker/Kubernetes).
🔹Hands-on experience using AI coding assistants (Claude Code, Cursor, GitHub Copilot, Codex, or similar) as part of the daily development workflow.
🔹English – Upper-Intermediate or higher.

What you will do:
🔹 Design, build, and operate high-throughput Go services on the real-time bidding and
header-bidding path, optimizing for latency, reliability, and cost at scale.
🔹 Develop and maintain Prebid integrations — Prebid Server adapters, bidder/identity
modules, and the supporting backend that powers them.
🔹 Build and harden integrations with ad-tech vendors (SSPs, DSPs, identity, and
measurement partners), including pixel, post-bid, and server-to-server flows
🔹 Profile and tune hot paths: concurrency, memory allocation, connection pooling, caching,
and request fan-out under high QPS
🔹 Own services through their full lifecycle — instrumentation, dashboards, alerting, and
participation in the on-call rotation.
🔹 Partner with product, QA, and business development to scope new partner integrations and
turn requirements into reliable, well-tested code.
🔹 Contribute to architecture decisions, code reviews, and engineering standards across the
Bidfusion team
