At Abysalto, that’s not just a motto — it’s how we work. We build serious tech for a variety of clients, but we keep things simple, fast, and focused. We’re a team driven by determination, expertise, and courage — and we’re looking for someone who shares that mindset. Someone ready to take ownership, solve real challenges, and make an impact where it matters. Ready to dive in? Join us as a AI Backend Developer in our Macedonian office!

🔷What will you do?

• Design, build, and maintain production-grade REST APIs in Python (FastAPI/Flask) that power AI-driven features
• Integrate and serve LLMs (OpenAI, open-source LLMs) and other NLP/ML models using frameworks such as PyTorch, Hugging Face Transformers, vLLM, llama.cpp, etc.
• Package models for deployment with Docker and automate delivery through CI/CD pipelines
• Write clean, well-tested code and participate in code reviews, and sprint planning
• Monitor, profile, and optimize APIs and model inference for performance and cost
• Collaborate with cross functional teams and contribute with ideas on architecture, MLOps best practices, and new AI capabilities
• Take ownership of your work, from concept to deployment — and refine it based on real-world feedback

🔷What do we expect from you?

• 1–3* years of hands-on Python development experience
• Solid grasp of modern web-service concepts: REST, JSON, authentication/authorization (OAuth2/JWT)
• Practical experience with at least one Python API framework (FastAPI preferred, Flask or Django acceptable)
• Basic familiarity with machine-learning libraries (PyTorch or TensorFlow) and model-serving patterns
• Basic knowledge of data handling: SQL (PostgreSQL/MySQL) and a NoSQL store (Redis, MongoDB, or similar)
• Comfortable with Git workflows and containerization (Docker); exposure to CI/CD tools (GitHub Actions, Jenkins, or GitLab CI)
• Basic cloud knowledge (AWS, Azure, or GCP)
• Eagerness to learn unfamiliar concepts quickly; whether that’s vector databases (FAISS/Milvus), prompt-engineering tricks, or new DevOps tooling
• Good written and spoken English; ability to explain complex ideas simply

🔷What we offer?

• Opportunity to shape our engineering culture from the early days
• Work in an experienced and encouraging team
• Continuous professional development through training and conferences
• Flexible working hours with the option of hybrid work
