• Ability to evaluate trade-offs between off-the-shelf agentic tools and custom API-based implementations.
• Genuine enthusiasm for and an informed opinion on where agentic tooling is heading.
• Strong full-stack fundamentals; comfortable owning significant pieces end-to-end across frontend and backend.
• Solid experience in any primary backend language (Java, Python, etc.) combined with React or any other modern frontend framework.
• Proactive, self-driven mindset, able to work independently without detailed instructions.
• Strong communication skills in English (B2–C1).
• Comfortable working in greenfield environments with evolving requirements.

• Camunda experience specifically is a significant advantage given the current architectural direction.
• Familiarity with AWS AI services; AWS AI Practitioner certification (AIF-C01) is a notable bonus.
• Exposure to cloud-native orchestration patterns and multi-agent system design.

Mindset & Soft Skills:

• Proactive and self directed, drives outcomes without waiting for direction.
• Comfortable with ambiguity, makes pragmatic decisions when the path is not fully defined.
• Strong technical communication, effectively collaborates with peer engineers to understand domain context.
• Forward thinking, stays current with the AI and agentic tooling landscape and brings new ideas.
• Energized by transforming software delivery, not just a participant but a believer.

We offer*:

• Flexible working format - remote, office-based or flexible
• A competitive salary and good compensation package
• Personalized career growth
• Professional development tools (mentorship program, tech talks and trainings, centers of excellence, and more)
• Active tech communities with regular knowledge sharing

Compensation

💰 Fixed salary — discussed individually 🌍 Fully remote 🎰 Industry: online casino / iGaming

👉 We're looking for someone who has been there — built it, scaled it, and kept it running in a high-stakes, high-traffic environment. If that's you, we want to talk.

About the role

Our team is building a platform for infrastructure optimization, including real-time rightsizing, AI-assisted autoscaling, workload analytics, and detailed cloud-spend analysis. We write primarily in Go, so Go experience is a plus. However, a strong backend foundation and concrete experience with Kubernetes, cloud infrastructure, and production systems matter more.

This role is intended for someone who already has hands-on experience with backend, cloud, or Kubernetes systems in production and wants to take on more demanding infrastructure work. You do not have to cover every technology listed, but you should have real experience with backend development, distributed systems, Kubernetes, or cloud infrastructure, especially on systems where scalability, stability, observability, automation, or infrastructure optimization were part of daily work. Because this role involves production infrastructure work, that hands-on experience matters more than familiarity with any single tool.

Your role and contributions

• Build backend services in Go. Design and ship backend services and components, primarily in Go. The code you write runs in production and underpins the broader infrastructure platform.
• Analyze node utilization and bin packing. Look at node utilization, resource requests, limits, and bin-packing strategies. Find where clusters waste money and propose specific fixes.
• Own architectural decisions and debugging. Participate in architectural decisions and debug complex production issues. Bring an opinion when it matters and a paper trail when it counts.
• Build Kubernetes operators and integrations. Work on Kubernetes operators and integrations with the Kubernetes API. Make the platform feel native to the people running real clusters.
• Build multi-cloud integrations. Integrate with AWS, GCP, and Azure to pull pricing data, manage node pools, and let users optimize cost regardless of provider.
• Develop AI-driven autoscaling and workload analytics. Build autoscaling logic that forecasts demand instead of reacting to it. Analyze workload patterns to drive smarter resource decisions.

• Build monitoring, observability, and cost analysis. Develop systems that surface real-time utilization, cost trends, and optimization opportunities. Help teams see what their infrastructure actually costs.

   

Required skills and qualifications
 

• Strong knowledge of Kubernetes, including hands-on experience with production Kubernetes environments
• Experience with cloud infrastructure — ideally AWS, GCP, or Azure
• Strong backend development experience in Go or a similar backend language
• Hands-on experience working with distributed systems in production
• Understanding of cloud APIs, infrastructure, and pricing models
• Experience with monitoring, observability, metrics, and logs
• Experience with IaC tools such as Terraform, Pulumi, or similar
• Ability to debug complex production issues
• Structured, independent, and collaborative approach to work

Nice-to-have

• Experience developing Kubernetes operators
• Professional Go experience
• Hands-on work with Karpenter, Cluster Autoscaler, or similar tools
• Experience with cloud cost optimization or FinOps
• Contributions to the Kubernetes or cloud-native ecosystem

About the role:

We're looking for a Product Manager to take full ownership of our core products — the tools our teams, clients, and partners rely on every day. You'll guide them from the first idea and roadmap all the way through launch and the improvements that follow.

You'll shape what we build and why, working closely with our Software Architect, designers, and engineers to turn business goals into real products that ship.

This is a hands-on role with a strategic edge. You'll help set the direction for the whole portfolio, but you'll also be in the details of the backlog every week. Think of yourself as the link between leadership, the people who build the product, and the people who use it.

What you'll do:

• Own the product strategy and roadmap across the full portfolio, balancing the long-term vision with what we deliver each quarter. You'll recommend what gets built, what gets cut, and what can wait.
• Turn that strategy into a clear, prioritized backlog. Write requirements and user stories that design and engineering can pick up and run with — without needing a follow-up meeting to figure out what you meant.
• Work with the Software Architect and engineering leads on trade-offs, scoping, and sequencing. You won't be writing code, but you'll be comfortable enough in these conversations to ask good questions and make sound calls.
• Partner with designers through discovery, prototyping, and testing, making sure the experience for users and the outcomes for the business line up.
• Keep everyone across the business aligned — leadership, sales, support, marketing. Communicate trade-offs honestly, and push back when it's the right thing to do.
• Talk directly with clients and partners when it sharpens our thinking — discovery calls, feedback sessions, and the like.
• Define what success looks like before work starts, then measure the results after launch so we actually learn what worked.
• Keep an eye on the market and competitors so the portfolio stays well-positioned and we spot opportunities early.

What we're looking for:

• 5+ years in product management, ideally with experience owning more than one product or a full portfolio.
• A track record of shipping, not just planning. We want someone who's taken ideas from a blank page to a live product more than once.
• Strong prioritization instincts. You can explain a "no" as clearly as a "yes."
• Comfortable working in agile teams and with tools like Asana, Notion, or Figma.
• Excellent communication, written and verbal. You can explain a trade-off to a non-technical exec and a business goal to an engineer, and both walk away clear.
• An analytical mindset. You reach for data before opinion, but you don't hide behind it.

• Genuinely at ease talking with customers and partners — you look for those conversations rather than avoiding them.

   

Working with AI:

We expect AI to be a real part of how you work — not a side experiment, but a daily habit. And if you're not fully there yet, you're eager to get there fast.

• You use tools like Claude or ChatGPT in your everyday product work: drafting PRDs and user stories, summarizing research, making sense of feedback, and pressure-testing your own thinking.
• You're comfortable setting up simple workflows where AI does a first pass — drafting or summarizing — and people review and refine.

• You know where AI tends to fall short, and you use it with good judgment.

   

Nice to have:

• Experience in logistics or a similar operations-heavy field.

About the project

We're building a smart customer behavior analytics platform for an e-commerce / retail business. A starter project is already done — we need an experienced developer to continue and expand it with new AI-powered video analytics features. Long-term engagement, 3+ months, with continuation after successful milestones.
 

What you'll be working on

• Face recognition & detection — identify returning customers
• Emotion detection — happy, neutral, surprised, confused, dissatisfied
• Age estimation & gender detection
• Object detection & tracking — products, shelves, zones, promotional areas
• Real-time / near-real-time video processing
• Detection overlays and analytics dashboard
• Customer emotion trends, demographic summaries, interaction heatmaps
• Camera input and/or uploaded video support
• Code review and improvement of existing codebase
   

Required skills

• Python, OpenCV
• YOLO (v8 preferred), DeepFace, InsightFace, and/or MediaPipe
• Face recognition and emotion detection in production
• Real-time video streaming (WebSockets / RTSP)
• Backend API development (FastAPI or Flask)
• Frontend integration — dashboards with live overlays
• Docker, GPU inference

Nice to have

• TensorRT / Triton for inference optimization
• Experience with retail or surveillance analytics systems
• Dashboard development (React or similar)

We offer

• Long-term project with stable workload

• Clear scope and existing codebase to build on

   

Are you in the top 1%?
 

Before anything else - this role is for genuinely outstanding people. The kind who have already proven, somewhere in their life, that they operate above the bar. For example:
 

• Winners or prize-holders of national/international Olympiads in Physics, Math, Informatics, Chemistry, etc.
• FLEX program alumni (or other selective international exchanges)
• Top of your class at UCU, LNU, KPI, KMA, or a comparable top university
• Top graduates of Physics-Math Lyceums and other selective schools
• Founders of something real - a startup, a community, a project that people actually used, even if it has failed eventually, but you've launched and got some early traction - we would love to hear from you. 
• Anyone with a verifiable record of being the sharpest person in the room
   

If that sounds like you, keep reading.

The job title is flexible - depending on your strengths and interests, you could grow into a Software Engineer, Data Analyst, AI Strategist, AI Product Owner, or another role we'll shape together.
 

What we're building
 

We're building a 100x company - and we need smart, ambitious people to build it with us. Our thesis is simple: AI is the biggest shift of our lifetime, and the people who learn to use it deeply will operate at 10x the speed and output of everyone else. If everyone in the company operates at 10x and the company is build around it - that's how we can achieve 100x company. We're putting that thesis into practice ourselves, and then helping our clients do the same through their AI transformation.
 

The deal

• You join us and spend your first phase learning - deeply - how to use AI to become 10x better at your craft - data analyst, software engineer, consultant etc. 
• You then work directly with our clients, helping them rethink and rebuild their workflows, products, and teams around AI
• You grow with the company as we scale toward a 100x outcome
   

What we're looking for

• Outstanding raw intelligence and curiosity (see the list above)
• Perfect level English - written and spoken
• A real track record of achievements, not just credentials
• Obsession with AI and a hunger to master it, even if you're not technical today
• Ownership mentality - you move fast, take initiative, and don't wait to be told what to do
   

Who this is NOT for

• People looking for a comfortable, predictable job
• People without real achievements to point to
• People who think AI is "just another tool"
   

How to apply

In your application, tell us the single most impressive thing you've ever done - Olympiad medal, exchange program, top ЗНО/НМТ results, a project you built, anything. Show us why you belong in the top 1%.
