Viso is an outsourcing company that has been on the market for over 3 years. We’re expanding our PMO as new projects come in, so we’re looking for a Project Coordinator to join the team and help keep delivery running smoothly.

It’s a hands-on operational role for a Strong Junior who already has commercial experience in IT outsourcing — we’re building a team of A-players and looking for people with exactly that potential.

💼 What you’ll do

You’ll help keep several small projects transparent and predictable for clients and the team:

• Keep clients updated — statuses, reports, and clear communication in the cadence they expect
• Track tasks, deadlines, and developer workload; make sure daily/weekly updates happen on time
• Help developers stay unblocked — coordinate with tech experts and keep the team supported
• Handle admin: time tracking, hours / scope / SLA, and HR/finance coordination (vacations, sick leave)

• Spot risks early and flag them with a possible solution — the PM makes the final call

   

🧠 What we’re looking for

• 6+ months of experience in an IT outsourcing/outstaff company in a coordination, PM-assistant, operations, or support role
• English B2 (written) — you write client statuses, reports, and notes yourself, no translator needed. Spoken B2+ is a plus
• Basic understanding of SDLC (PR, commit, sprint, backlog, release) — you don’t code, but you follow what developers discuss
• Confident with tracking tools (Notion / Jira / Asana / ClickUp)

• Comfortable with numbers — hours, limits, SLA

   

And the traits that matter most to us:

• Ownership — you follow through on your tasks without needing reminders
• Proactivity — you raise issues early and come with a suggestion, not just the problem
• Organization — you keep your own system for deadlines and rhythm
• Clear communication — you talk to developers and clients directly, and pull out the real blocker instead of settling for “all good”
• Client-growth mindset — you get that the goal isn’t just to run a project, but to help the client and their product grow. You won’t be doing this from day one, but you keep that lens as you develop

✨ Nice to have

• Product thinking; basic BA skills (user stories, acceptance criteria)

🎁 What we offer

• 14 days paid vacation + 5 days paid sick leave; extra days off for work anniversaries and blood donation; referral program
• Hybrid / on-site, Lviv office (Stryiska St. 108) — candidates based in Lviv preferred
• Flexible start between 8:00-10:00; cozy office with coffee, fruits, sweets, and a sunny terrace

Job Summary

As a Software Engineer, you will review AI-generated code and compare it with how you would write the solution yourself. Your main responsibility will be to evaluate AI-generated solutions, identify mistakes, and uncover reasoning gaps.
Right now, our developers are helping other engineers who work with AI get more accurate and reliable code. So, if you’ve ever written a prompt for AI and received a great answer, there’s a chance that work done by our developers helped make that answer better.

Requirements

• 3-4 years of hands-on experience as a Software Developer on commercial projects, including B2B SaaS systems and data-heavy applications.
• Use AI tools (AI agents, Claude Code, Cursor, Codex or similar) in daily workflow.
• Experience working with existing codebases and unfamiliar repositories
• Strong experience with Node.js
• Strong knowledge of JavaScript / TypeScript
• Experience with backend frameworks such as Express.js or NestJS or Fastify
• Good understanding of REST API and backend architecture
• Experience working with databases (SQL and/or NoSQL)
• Ability to independently analyze code and identify bugs or inconsistencies
• Strong analytical and problem-solving skills
• Upper-Intermediate English (B2)

Key Responsibilities

• Work with Frontier Labs, producing training data to train Al models.
• Evaluate AI-generated code, technical solutions, and engineering approaches.
• Identify bugs, incorrect assumptions, architectural issues, and weak reasoning in AI responses.
• Test and evaluate agentic coding models designed to perform complex engineering tasks at a senior developer level.
• Compare AI-generated solutions against senior engineering standards and best practices.

Bonus:

• Computer Science or related education.
• Learning new programming languages.
• Strong understanding of algorithms and data structures.

This is not a traditional software development role. You will use your engineering expertise to analyze AI outputs, find issues in their solutions, and help train better AI systems.

Viso is an outsourcing company that has been on the market for 3 years. We’re in an active growth phase — moving into new markets and taking on bigger, more ambitious projects — and that’s exactly why we’re opening this role.

We’re looking for a Senior BDM & Growth Manager who owns the full sales cycle, brings in new clients, and works closely with the CEO to spot where we grow next. This is a hands-on role — you own deals end to end, from first call to signed contract.

🎯 The mission

Drive new business for Viso: find opportunities, run them from first call to close, and turn them into closed deals and revenue. Beyond the classic sales plan, you’ll help identify new markets, partnerships, and growth angles worth testing — and you’ll be the one running the experiments, not just proposing them.

This is a role for someone who doesn’t wait for a ready-made plan — you find opportunities on your own, form hypotheses, test them, and turn them into concrete results.

💼 What you’ll do

Full sales cycle (the core of this role)

• Run discovery and qualification calls, understand the client’s real business problem, shape a relevant offer, present the solution, lead commercial negotiations, and close deals.

   

Strategic partnerships

• Find and build partnerships that bring in clients, open access to new markets, or create new revenue opportunities.

   

A managed pipeline

• Build and grow a stable pipeline of new clients and business opportunities, and own its quality, momentum, and results.

   

Influence on strategy

• Bring market signals and ideas to the CEO and help shape where we grow next — testing new directions, segments, and offers through your own deals.

🎁 What we offer

Earnings & upside

• Fixed salary + a performance bonus that grows with your results — the more you close, the more you earn
• A transparent bonus model tied directly to the deals and revenue you bring in

What you’ll be selling

• A strong technical team behind you that delivers what you sell — you close with confidence, not crossed fingers
• Real projects and clients to reference, across clear markets and domains
• Business trips abroad on the roadmap — industry events and on-site visits to clients — as we grow into new markets

Autonomy & influence

• Direct access to the CEO — short decision loops, no bureaucracy
• A real say in which markets and directions we pursue next
• Room to grow the function — and your role in it — as results come in

The essentials

• Hybrid / on-site at our Lviv office (Stryiska St. 108)
• Flexible start between 8:00 and 10:00
• 14 days of paid vacation + 5 paid sick days a year
• Paid English lessons and development courses to keep growing
• A modern, comfortable office and a referral program

🧠 What we expect

• 3+ years in B2B Business Development / Sales in software development, IT outsourcing, AI / tech consulting, or digital product development.
• Experience running the full sales cycle and closing B2B deals yourself.
• Experience with consultative or solution selling.
• Experience working with US / UK / European markets.
• Strong negotiation skills with founders, C-level, and senior stakeholders.
• English at a level sufficient to run negotiations with international clients on your own.
• A high level of ownership — you find opportunities, not just wait for them.
• An AI-first GTM mindset.
• Based in Lviv and able to work from our office in a hybrid format.

✨ Nice to have

• Openness to business trips abroad.
