The posting

We’re looking for a Senior Software Engineer who combines strong technical depth with independence, ownership, and the ability to work directly with clients.

You’ll join one of our cross-functional pods, working on enterprise-level, AI-powered solutions for large clients. This is a role for someone who doesn’t just implement tickets, but can understand the bigger picture, make sound technical decisions, take ownership of outcomes, and help steer a project from architecture through production.

What you’ll do

  • Design and develop enterprise-grade AI-powered software solutions for large clients.
  • Take ownership of technical decisions and help shape the architecture of projects.
  • Design and implement solutions across the stack, including backend, databases, cloud infrastructure, and DevOps.
  • Work primarily with .NET or Python; experience with Java or Node.js is also valuable.
  • Contribute to the frontend when needed, with React experience being a strong plus.
  • Work with AI technologies and integrate AI capabilities into robust, production-ready applications.
  • Work directly with clients: understand their needs, explain technical trade-offs, provide guidance, and challenge assumptions when necessary.
  • Work independently while collaborating closely with other engineers and specialists within your pod.
  • Help establish technical direction, identify risks and dependencies, and make pragmatic decisions.
  • Take ownership when things get difficult: prioritize, lead, de-escalate, communicate clearly, and defend your technical position when you believe it is the right one.
  • Help ensure that solutions are scalable, maintainable, secure, and suitable for enterprise environments.

What we’re looking for

Essential

  • Bachelor’s or Master’s degree (or higher) in Software Engineering, Computer Science, Artificial Intelligence, or a related technical field.
  • Strong professional experience as a Software Engineer, with significant technical depth.
  • Expert-level proficiency in .NET or Python.
  • Strong understanding of software architecture and the ability to design systems beyond individual components.
  • Experience with databases, cloud infrastructure, and DevOps.
  • At least a working understanding of frontend development; React experience is preferred.
  • Experience using AI tools in your everyday development workflow — we expect you to actively use AI to improve how you work.
  • Ability to work independently and take genuine ownership of technical outcomes.
  • Strong communication and collaboration skills, including the ability to work directly with clients.
  • Ability to make decisions in ambiguous situations, prioritize effectively, and stand behind your technical judgment.
  • Fluency in English.

Strongly preferred

  • Experience building and operating AI-powered solutions in production, particularly in enterprise environments.
  • Experience with LLMs, AI agents, RAG, AI integrations, or other modern AI application patterns.
  • Experience designing cloud-native architectures.
  • Experience working across the full software lifecycle, from architecture and development through deployment and production operations.
  • Experience with React and modern frontend development.
  • Experience working in consulting, client-facing engineering, or similarly collaborative environments.

Why join us?

  • Our developers work on only one project at a time, no context switching
  • We strive towards long-term collaboration, you have the opportunity to get to know the client and his needs well, as well as the team
  • You will have the opportunity to work on complex solutions with the latest technologies
  • Remote work means it's up to you whether you work from home, on the beach, or in the office
  • Flexible working hours mean that you can tailor your workday to your preferences, without a time-tracking system
  • All our employees will right away receive a contract for an indefinite period (B2B collaboration is also an option)
  • We provide regular feedback as part of our commitment to your ongoing development and success
  • If you love taking courses or going to conferences, we are always open to discussing education opportunities, especially in the realm of AI and cloud
  • Each team has its own monthly knowledge-sharing sessions combined with weekly talks and brainstorming sessions aimed at improving our current work and processes
  • If you have a colleague or a friend who could be a good fit for us, we can offer you a referral fee
  • Salary will be based on your experience and skills

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
