Responsibilities

• Develop rich, interactive
  - end applications using React. js (or similar), focusing on performance, maintainability and user experience.
• Build
  - end services using either. NET (C#) or Python (Fast
  API) — implementing clean APIs, business logic and data flows.
• Participate in deploying and operating in cloud environments (preferably Microsoft Azure) — including infrastructure as code, CI/CD, monitoring and logging.
• Integrate AI/LLM capabilities (such as chatbots, embedding search, generative features) into
  - stack solutions.
• Ensure solutions are scalable, performant, secure, maintainable and
  - tested.
• Collaborate
  - functionally with product managers, data scientists, Dev
  Ops engineers to deliver
  - quality features.
• Contribute to engineering best practices, code reviews and continuous improvement (less formal mentoring than Lead role, but still supporting peers).
• Stay current with
  - stack, cloud, AI/LLM trends and help evaluate how they can be leveraged in our context.

What You Bring to the Table

• 3-5 years of full stack engineering experience building production systems.
• Strong
  - end skills: React. js (or equivalent), component design, state‑management, user‑centric interfaces.
• Proven back‑end proficiency in either. NET (C#) or Python (Fast
  API) — comfortable writing clean, well‑tested APIs.
• Experience working in cloud environments (Azure preferred) and familiarity with cloud services.
• Hands‑on experience or strong eagerness to work with Dev
  Ops: CI/CD pipelines, infrastructure as code (Terraform or similar), automation, monitoring.
• Experience or interest in AI/LLM integration (embedding search, generative features, conversational interfaces).
• Strong collaboration skills — you enjoy working in cross‑disciplinary teams and communicating technical ideas clearly.
• A problem‑solving mindset, ownership of your work from design through deployment.
• Good communication skills in English.

Why Join Us?

• Work on exciting
  - stack + AI-enabled products where you’ll have real impact.
• A collaborative, open culture that values innovation, learning and teamwork.
• Opportunity to grow: mentor others, shape architecture, drive technical strategy.
• Flexible working model (remote/hybrid), modern tech stack, investment in your development.
• Join a team of passionate engineers, data scientists and product thinkers — where AI isn’t just a buzzword, but part of the solution.
