• Potential Engineering Coordination: Depending on experience and interest, take ownership of internal operational workflows for technical teams (e.g., Platform Engineering/DevOps or Frontend) to help package their work into clear, visible deliverables.

AI-Native Mindset

At our company, AI is a core multiplier for daily efficiency. We are looking for a candidate who is genuinely enthusiastic about integrating AI into their daily workflow:

• Comfortable using AI tools (e.g., ChatGPT, Claude, Cursor, Asana automations) to write task descriptions, generate documentation, draft client communication, and automate routine project management tasks.
• Eager to explore new AI tools to streamline processes without resistance to adopting modern tech practices.

Who You Are

You are an energetic, proactive, and creative problem-solver who thrives in client-facing technical environments:

• Strong Communicator: Excellent interpersonal skills with the ability to navigate client expectations, explain technical nuances, and keep all stakeholders aligned.
• Technical Aptitude: Understand the basic mechanics of software development and DevOps workflows (e.g., builds, Pull Requests, deployments) to speak the same language as developers.
• Independent & Resourceful: Able to work autonomously, dig into integration mechanics, and structure chaotic requests into actionable project plans.
• Adaptable: Comfortable working with global teams across EU and US timezones when occasional late syncs are needed.

Qualifications

• English: Upper-Intermediate or Advanced (both written and verbal) for daily client and internal communication.
• Experience: 1+ years of professional experience in Project Management, IT Delivery, or Technical Account Management.
• Client-Facing Background: Proven experience managing client onboarding, custom software requests, or delivery projects.
• Technical Literacy:
  • Understanding of API integrations, web hooks, or third-party connections.
  • Basic familiarity with software delivery concepts and CI/CD/DevOps basics (PRs, builds, environments).
  • Hands-on experience with modern task tracking and documentation tools (Jira, Asana, Confluence, etc.).

Bonus Points:

• Experience in Fintech, Web3, Crypto, or Prediction Markets.
• Direct experience with liquidity provider integrations, payment gateways, or card issuer APIs.

• Practical experience using AI tools to automate project management routine.

   

We Offer

• Flexibility & Hubs: Flexible working hours with physical office access in Ukraine and Poland (Wroclaw).
• Health & Wellness: Medical Insurance in Ukraine and Multisport program in Poland.
• Time Off: Paid vacation, sick leaves, and observance of official holidays.
• Growth: English classes (up to 3x weekly), mentoring, and educational opportunities.

Are you detail-obsessed, analytical, and ready to learn how e-commerce actually works at scale?

Argo Brands is a US-based consumer goods company with four active brands — including top-selling Amazon products with 50,000+ reviews. We sell across Amazon, TikTok Shop, Shopify, Walmart, Target, Kohl's, and Snappy. We're growing fast and need a sharp, reliable person to support our marketplace operations team.

This is an entry-level role. We're not looking for someone who already knows everything — we're looking for someone who is organized, analytical, persistent, and genuinely excited to learn how marketplace operations work from the inside. We'll invest in training you. In return, we need someone who takes ownership, catches mistakes before they become problems, and doesn't need to be chased.

What You'll Do

• Support day-to-day operations across four retail marketplaces: Walmart, Target, Kohl's, and Snappy
• Create and optimize product listings — titles, descriptions, bullet points, keywords, images
• Build and maintain spreadsheets, trackers, reports, and dashboards
• Monitor advertising performance and key business metrics across platforms
• Track P&L, profitability, and operational KPIs
• Automate repetitive tasks using AI tools and help improve team workflows
• Analyze data and flag opportunities or issues to the team
• Prepare reports, summaries, and presentations for management
  
  Who We're Looking For
• We're open to two profiles:
• Students or career-starters with no direct experience — if this is you, what matters most is strong English (written and spoken), an analytical mindset, high attention to detail, and the ability to stay focused and accurate on repetitive tasks for extended periods. If you're the type who notices errors others miss and takes pride in clean, structured work — we want to hear from you.
• Candidates with 1+ year of experience on Amazon, Walmart, or any other marketplace — your hands-on knowledge of listing management, advertising metrics, or operational workflows is a strong advantage.
  
  You're the Right Person If
• You take ownership and drive tasks to completion without needing constant check-ins
• You notice inconsistencies, errors, and missing information before they become problems
• You organize information clearly and naturally create repeatable processes
• You're proactive — you identify opportunities for improvement and suggest solutions
• You're a fast learner who adapts quickly to new tools, platforms, and workflows
• You actively use or are genuinely curious about AI tools to improve productivity
• You're comfortable working with data, metrics, and performance analysis
• You perform well in a fast-paced environment where priorities shift
• You can stay focused and accurate on repetitive, detail-oriented tasks over time
  
  Hard Skills (Required or Learnable)
• Strong Excel or Google Sheets skills — or a clear ability and willingness to develop them
• English proficiency — written and spoken (this is a must, as all work is in English)
• Basic understanding of e-commerce or marketplace logic (Amazon, Walmart, or similar) is a plus, not a requirement
• Familiarity with AI tools (ChatGPT, Claude etc.) is a strong plus
  
  What We Offer
• Full training and mentorship — we'll teach you how marketplace operations work at a real scale
• Remote work
• A front-row seat to how a multi-brand US e-commerce company operates across major retail platforms
• Real responsibilities from day one — this is not a "shadow someone" internship
• Clear growth path as you develop expertise
• A fast-moving, international team that values ownership and initiative

What will you do after training?

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:
The company is on a mission to make the world’s industrial environments safer with technology solutions and to drive a paradigm shift in safety from reactive to proactive approaches to reduce the risk of industrial accidents. The team in Ukraine is developing the future of industrial safety based on machine learning, computer vision, and IoT.

About the role:
We're looking for a systems-minded Senior Software Engineer to build the performance-critical core of our real-time computer vision pipeline. You'll own the runtime beneath the CV engines - shared-memory frame pools, zero-copy IPC, and process orchestration - where the bottleneck is memory bandwidth and microseconds, not network or nodes.

Responsibilities:
- Collaborate with CV/ML engineers to turn model inference code into reliable production pipeline stages. 
- Develop and optimize the core Pipeline Engine - an in-process, real-time runtime that runs the CV pipeline as a graph of stages, where latency is measured in milliseconds. 
- Use and extend the zero-copy shared-memory pools that pass frames between processes (C core + Python/Go bindings). 
- Build and tune low-latency ZeroMQ communication layers for passing control messages, metadata, and synchronization signals between pipeline components.
- Work with pipeline metadata formats and serialization boundaries, with awareness of performance tradeoffs around FlatBuffers or similar schema-based binary formats.

Requirements:
Must-have: 
- Senior-level engineering experience in performance-sensitive systems, with strong systems thinking: concurrency, process models, memory ownership, data movement, latency/throughput tradeoffs, failure modes, and profiling. Practical Python experience is expected, but the core requirement is systems-level reasoning. 
- Experience building or operating real-time ML/CV inference pipelines, video processing systems, robotics perception stacks, or other latency-sensitive data-processing runtimes. 
- Solid experience with Docker and containerized environments;
- Solid Linux fundamentals.

Nice-to-have:
- Basic understanding of CUDA, including IPC handle management, stream synchronization;
- Knowledge of C/C++/Go.
- Experience with video/CV infrastructure: OpenCV, GStreamer, FFmpeg, RTSP streams, or camera pipelines.

The company offers:
- English classes;
- PE support by professional accountants;
- 40 days of PTO;
- Medical insurance;
- Team-building events, conferences, meetups, and other activities;
- There are many other benefits you’ll find out at the interview.
