Join the AI revolution. We’re building an all-in-one AI platform to help teams do their best work and automate every routine task you can think of. We’re looking for problem-solvers to turn powerful AI into an easy, no-code tool for teams everywhere.

At nexos.ai, we’re building infrastructure to help organizations adopt AI securely and at scale.
We’re now hiring a Customer Engineer to strengthen the technical side of our team. This role is ideal for engineers who enjoy solving real-world problems directly with customers. You will work closely with the Product and Engineering teams, supporting customer-facing initiatives—from discovery and prototyping to onboarding and feedback loops. Your goal will be to ensure technical clarity, credibility, and success across the customer journey.

Main Responsibilities:

  • Act as the technical counterpart to enterprise customers- helping understand requirements, define solutions, and map them to our product capabilities.
  • Support technical discovery, solution design, and architecture discussions in collaboration with Sales and Product.
  • Deliver hands-on product demonstrations, technical evaluations, and proofs of concept (PoCs).Translate complex customer needs into product configurations or implementation approaches.
  • Act as a feedback bridge between the field and our Engineering team- reporting product gaps, technical blockers, and usability issues.
  • Ensure smooth onboarding by assisting with integrations, APIs, and infrastructure alignment.
  • Maintain relationships with technical stakeholders on the customer side, including engineering and IT/security teams.
  • Develop and maintain internal documentation, reusable code snippets, and solution templates.
  • Contribute to internal knowledge sharing on customer use cases, deployment patterns, and implementation lessons learned.

Core Requirements

  • 3+ years of experience in data engineering, data analytics, or data science, or a technical role in the data field. Experience in software engineering, solution engineering, or technical consulting could also be considered.
  • Solid understanding of SaaS platforms, cloud infrastructure (AWS, GCP, Azure), APIs, and data security best practices.
  • Exposure to AI/ML systems and tooling—either through implementation or integration work.
  • Experience delivering technical PoCs, proof-of-value projects, or integration pilots with enterprise clients.
  • Strong troubleshooting and systems thinking abilities—comfortable navigating complex IT and data environments.
  • Clear communicator, able to articulate technical topics to both internal and external teams.
  • Comfortable working in a high-velocity environment with frequent cross-functional collaboration.
  • Fluency in English (written and spoken); additional languages are a plus.
  • Willingness to occasionally travel for customer sessions or events.

Salary Range

Gross salary is 17 000 - 29 885 pln/month + OTE Bonus. We are open to adjusting this based on the depth and relevance of your experience.
