Jobs at Djinni

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 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.

ob Description

• 6+ years of commercial experience working on the backend as a .NET engineer
• Hands-on experience in web services development (REST/SOAP)
• Experience in ASP.NET/MVC/ASP.NET Core Web API
• Experience with .NET Core 8
• Experience with NHibernate or other ORM tools
• Experience with Unit testing (Moq, Substitute, etc)
• Database skills (MS SQL; writing/analyzing queries; understanding of DB design)
• Experience with Message Brokers (RabbitMQ, Service Bus, or similar)
• Development of cloud products (AWS as a plus)
• Ability to diagnose/solve problems
• Good level of communication and reporting skills
• English — Upper-Intermediate and 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

About Gravira Group

Gravira Group is a product iGaming company focused on Tier-1 markets.

We build and scale our own products by combining Product, Acquisition, CRM, Payments, Engineering and Analytics into one high-performance system.

We move fast.

We make decisions based on data.

We trust ownership over bureaucracy.

Why this role exists
 

Every percentage point of conversion directly impacts revenue.

When metrics change, we don’t guess.

We investigate.
 

Sometimes the reason is traffic quality.

Sometimes it’s tracking.

Sometimes it’s a redirect.

Sometimes it’s infrastructure.

Sometimes it’s the product itself.
 

Your mission is to uncover hidden problems across the acquisition funnel before they become visible business losses.
 

What You’ll Own

You won’t spend your days building dashboards.

You’ll investigate the entire acquisition funnel and connect data with product behaviour.

Your responsibilities will include:

• Investigating traffic quality across Affiliate, Facebook and other acquisition channels.
• Performing root cause analysis for conversion drops.
• Diagnosing the acquisition funnel from click to repeat deposit.
• Validating tracking links, redirects, attribution, cloaking and postbacks.
• Identifying bottlenecks affecting:
  • Click → Registration
  • Registration → Deposit
  • Deposit → Repeat Deposit
• Investigating issues related to:
  • devices
  • browsers
  • landing pre-landing pages
  • operating systems
  • internet providers
  • provinces
  • payment flows
  • infrastructure
• Collaborating with Product, Affiliate, Media Buying, QA, Payments and Engineering to identify root causes instead of symptoms.
• Building clear hypotheses, validating them with data and turning them into actionable recommendations.
• Monitoring funnel health and detecting anomalies before they significantly impact acquisition performance.

• Conversion issues are identified before they become major business problems.
• Funnel visibility is significantly stronger.
• Affiliate and Media Buying teams clearly understand why performance changes.
• Product decisions are driven by evidence instead of assumptions.
• Technical issues are discovered faster.
• Teams spend less time debating symptoms and more time solving root causes.
• Performance metrics are increasing the performance of Marketing teams.
   

We’re Looking For Someone Who

• Has 3+ years of experience in Performance Marketing Analytics, Growth Analytics, Product Analytics or similar roles.
• Understands affiliate marketing and paid acquisition.
• Knows how tracking, redirects, attribution, and postbacks work.
• Can investigate technical conversion problems instead of simply reporting numbers.
• Is comfortable working with SQL and modern BI tools.
• Naturally asks “Why?” before drawing conclusions.
• Enjoys connecting data, product behaviour and business impact.
• Communicates clearly with both technical and non-technical teams.
• Takes ownership and proactively drives investigations through to resolution.
   

Nice to Have

• Experience in iGaming, Betting or Gambling.
• Experience with Tier-1 markets, especially Canada.
• Experience with Binom, Keitaro, Voluum or similar tracking platforms.
• Experience with GA4, Looker Studio, Tableau or Power BI.
• Understanding of Cloudflare, CDN, or WAF.
• Browser debugging experience.
• Experience with Hotjar or Microsoft Clarity.
   

Why Gravira Group

This is a place for people who like ownership.

You’ll work directly with experienced Product, Acquisition and Engineering teams.

Your ideas won’t disappear into layers of approvals.

If your investigation changes the direction of the product, we’ll act on it.
 

We value curiosity over assumptions.

Evidence over opinions.

Speed over bureaucracy.

And people who leave every system better than they found it.
 

Build Gravity of Luck

At Gravira Group, luck isn’t random.

It’s the result of curiosity.

Of ownership.

Of speed.

Of hundreds of small improvements that compound over time.

If you’re the kind of person who can’t stop investigating until you understand why, you’ll feel at home here.
