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.

Our client runs a top-20 global gaming hosting product and is now launching a second, standalone B2C product — managed WordPress & AI-tools hosting.

Tech, payments, and legal structure are ready; the product needs its first marketing hire to build acquisition from scratch.

Main Responsibilities

• Own traffic acquisition end-to-end: launch and run SEO and/or PPC as a hands-on practitioner
• Set channel/market priorities, own and allocate a monthly budget in the $50–100K range
• Build and hire a small marketing team (starting ~5 people, with access to 20+ marketers company-wide)
• Set up analytics and unit economics (CAC, LTV, payback, contribution margin)
• Run a continuous testing process (A/B tests, hypothesis-driven growth)

Mandatory Requirements

• 3+ years hands-on, practitioner-level expertise in SEO or PPC
• Experience managing a team of 5+ people, including hiring and development
• Proven experience managing budgets of $50K+/month
• Solid grasp of unit economics and A/B testing methodology
• Strong analytical, energetic, results-first mindset — decisions driven by data, not activity volume
• High autonomy: comfortable operating with ambiguity and owning outcomes

Nice-to-Have

• Experience in hosting, SaaS, or subscription/B2C products (strong plus)
• Multi-channel expertise (SEO + PPC) rather than single-channel
• Tier-1 market experience (US, UK, Germany)

We offer

• Salary review every 6 months
• Real ownership: your own budget, channel decisions, and a small team to build out
• Clear growth path to leading the entire product line (P&L, product, team) if you deliver
• High-trust, low-bureaucracy environment — no micromanagement, results speak for themselves
• Fully remote, async-friendly culture
• Standard paid time off (vacation/sick days)

📍 Location: Limassol, Cyprus

Aloha Mobile Ltd. develops Aloha Browser - a privacy-focused browser available across major platforms with 200M+ installs worldwide.
 

The product combines secure browsing, native encrypted VPN, advanced ad-blocking, privacy technologies and local/on-device AI. The company is actively developing agentic AI capabilities and building the next generation of privacy-first browsing experiences.

We are looking for a Chief Technology Officer who can combine deep technical expertise, strong engineering leadership and a product/business mindset.
 

The role

This is not a purely managerial CTO position.

We are looking for a hands-on technology leader who can own the technical vision, make architectural decisions, lead strong engineering teams and translate business/product KPIs into concrete engineering priorities.

The CTO will work closely with the Founder/CPO and C-level team and take ownership of technology decisions that directly impact MAU, LTV, product performance and company growth.
 

Key responsibilities

• Own the overall technology strategy and architecture across iOS, Android and Desktop.
• Lead and scale engineering teams working on a consumer product used by millions of users.
• Drive architecture of high-load, distributed and highly available systems.
• Translate business and product KPIs into engineering initiatives and measurable technical goals.
• Drive development in privacy, security, networking and local/hybrid AI.
• Lead high-impact R&D initiatives and evaluate new technologies based on their actual product/business impact.
• Ensure engineering excellence across performance, scalability, reliability and security.
• Build, develop and retain a high-performing engineering organization.
• Work closely with Product and other C-level stakeholders on product and technology strategy.
• Ensure compliance with Apple/Google platform requirements, privacy standards, security governance and global data regulations.
   

What we’re looking for

• Proven experience as CTO / VP of Engineering / Head of Engineering or in a comparable senior technology leadership role.
• Experience building and scaling mass-market B2C products with millions of users.
• Strong technical background — we need a CTO who can go deep into architecture and engineering, not only manage people.
• Strong expertise in mobile applications and/or browser technologies.
• Deep understanding of high-load distributed systems and architecture.
• Strong knowledge of low-level networking, security and cryptography.
• Experience or strong technical understanding of modern AI/ML, local/on-device or hybrid AI frameworks.
• Proven experience building and leading high-performing engineering teams.
• Strong data/product mindset: ability to connect engineering decisions with MAU, LTV and other business/product metrics.
• Ability to turn complex goals into clear technical priorities for engineering teams.
• Understanding of privacy, data sovereignty, security governance and App Store / Google Play ecosystems.
   

Strong advantage

Experience in one or several of these areas will be particularly valuable:

Browser technologies / AI companies / Mobile B2C / High-load consumer products / Backend & distributed systems / Privacy & Security.

Background in a successful technology startup or rapidly scaling product company is also highly relevant.
 

What matters beyond the CV

We are looking for a technology leader who is:

• Data & metrics driven
• genuinely interested in R&D and emerging technologies
• hands-on enough to challenge architectural decisions
• product-oriented and understands how technology affects growth
• comfortable taking ownership of ambitious measurable goals
• curious, pragmatic and able to make technology bets based on business impact
   

Hiring process

Recruiter interview → CEO/CPO interview → iOS/Android Engineering Leads
 

📩 If you have built technology for products used at massive scale and want to combine architecture, mobile, AI, privacy and product growth, I’d be happy to tell you more about the role and Aloha.

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)
• Excellent spoken and written English
• The patience and structure to work day to day with a fast-moving, idea-heavy founder
   

Nice to have: behavioral/clickstream analytics, fraud/anomaly detection, survey methodology/psychometric.
 

Stack: Python, PyTorch, LightGBM, MLflow, HDF5, PostgreSQL.
 

Not an LLM/GenAI role: this is classical ML and deep learning on structured behavioral data.

The Team

• Playing Founder
• Project Manager
• ML Engineer
• 2x Fullstack Devs
• Anti-Fraud Automation QA
• DevOps

For fulltime players we offer:

• 15 paid day-offs per year.
• 10 US/UA holidays.
• Flexible schedule and fully remote work from anywhere with reliable overlap to CET.
• Senior team members.
• Minimal bureaucracy, high authonomy and trust, fast decisions.
