Data Science UA is a service company with deep expertise in AI and Data Science. Our story started in 2016 with the first Data Science UA Conference in Kyiv, and since then, we’ve built one of the largest AI communities in Europe.

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 Software Engineer to work on the performance-critical core of a real-time Computer Vision platform.

This is not a typical 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++ or Python 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 C++ or Python.
• 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.

• Experience with Docker and containerised environments.

   

Nice-to-have

• CUDA, including IPC handles and stream synchronisation.
• 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.

Хелоу, люба спільното \0/

Ми продовжуємо нарощувати команду американського Survey SaaS, що аналізує поведінку юзерів під час digital опитувань. По суті, це платформа, де бізнес може засетапити своє опитування та отримати advanced behavioural analytics від нашої моделі на підставі того, як юзер водив мишою, відповідав на різні питання, тупив та чухався.

Вам сподобається, якщо:
- в вас ідеальний інгліш. Це найважливіший фактор. Треба багато діскутувати на складні теми. Якщо вам здається, що в вас не супер сильний інгліш – го не гаяти часу.
- в вас достатньо терпіння для щоденної роботи із гіперактивним фаундером, в якого багато ідей, іноді протилежних.
- ви вмієте поєднувати грацію науки та експеріменти на колінці (напр.: взяти наукову роботу про кореляцію відповідей із часом на роздуми та придумати як превірити це за нишими даними не за мільйон доларів та часу).

По суті, нам потрібен Scientific Lead, який буду допомагати фаундеру народжувати проект, покриваючи наукову та ML частину самостійно, або за допомогою нашого ML Engineer.

На цьому я дозволю перемкнутись на англійську, бо далі конкретніше.

What you'll do

• Act as the scientific and ML lead next to the founder, turning a stream of ideas (sometimes conflicting ones) into testable hypotheses and priorities
• Design lean experiments: take a research paper (e.g. how thinking time correlates with answer quality) and find a cheap, fast way to test it on our data
• Set tasks for our ML Engineer and review the work, or build it yourself
• Own model quality: evaluation methodology, calibration, segment-level analysis, precision/recall tradeoffs
• Keep work reproducible and audit-ready (experiment tracking, clean notebooks, documented results)
   

What you need

• Deep learning on sequence/time-series data (PyTorch, CNNs built from scratch)
• Tabular ML with gradient boosting (LightGBM / XGBoost)
• Rigorous evaluation: imbalanced classification, threshold tuning, AUC-ROC, calibration, label quality
• Solid experimental design and the ability to turn research into practice
• Experiment tracking (MLflow, W&B or similar)

About Company

Wise Engineering is a software company where 90% of client relationships turn into long-term partnerships, and 70% of the team are senior-level engineers. We're hiring for one of our client products.

About the Project
A secondary school scheduling platform built by former educators who lived the problem firsthand. The school schedule is one of the most consequential decisions a district makes - it shapes how staff and students spend their time, what positions are needed, and how resources are allocated across schools. With AI-powered optimization and hands-on support, the platform helps school and district leaders build schedules that reflect their academic, staffing, and budget priorities - while saving hundreds of hours in the process.

About the Role

Senior Software Engineer responsible for full-stack development of the platform's data integrations ecosystem. You will build the product and infrastructure that enables schools and districts to send and receive data to the scheduling application, and participate in limited direct customer support to stay close to real integration challenges. 

Strong English is a hard requirement - you'll work directly with non-technical

stakeholders on the customer side.

Responsibilities:

• Build and maintain data pipelines - import, validation, transformation, and export of customer data across 100+ school information systems
• Work directly with customers to enable and troubleshoot their data integrations
• Design and deliver tools and infrastructure that make the integration process more reliable and scalable
• Own key architectural decisions in your product area
• Introduce and apply AI-assisted approaches to parser and exporter development
• Own production availability - observability, incident response, and fixing what you ship
• Mentor engineers on the integration team and contribute to cross-team knowledge sharing

Requirements

Technical Skills

• 3–5+ years of experience in backend or integration-heavy domains
• Hands-on experience with data pipelines, parsers, or system integrations (SFTP, APIs, custom formats)
• Proficiency in Python and async patterns
• English C1 - you'll communicate directly with customers, often non-technical ones
• Strong ownership mindset - comfortable in a fast-moving startup with limited hand-holding
• Experience with LLM/generative AI in a production or development context - building with it, not just using Copilot

• Prior EdTech experience is a plus

   

Experience & Soft Skills

• English C1 or higher - customer-facing role requiring clear communication with non-technical stakeholders!
• Strong problem-solving skills with the ability to navigate ambiguous, loosely defined integration requirements
• Proactive communicator - keeps stakeholders informed, surfaces blockers early, doesn't wait to be asked
• Comfortable working collaboratively across product, engineering, and customer success teams
