About Company

Company is a fast-growing US startup currently in its seed round, building cutting-edge AI-powered products that simplify complex processes and deliver real impact.

The team moves fast, values initiative over bureaucracy, and thrives in an environment where speed, ownership, and innovation drive every decision. Here, every line of code directly shapes the product and the user experience. It’s a place for builders who care about the why as much as the how.

The Role

We’re looking for a Senior Backend Developer who’s passionate about building products from the ground up, not just features. Someone who loves thinking about how everything fits together, contributes to the full product lifecycle, and takes ownership of their work end to end.

This role focuses primarily on the backend (preferably in Python), but may occasionally support frontend components, as expected in a dynamic, early-stage startup environment. The ideal candidate is self-driven, proactive, and comfortable navigating ambiguity with a hands‑on, problem‑solving mindset.

Responsibilities

• Design, develop, and maintain scalable backend systems and APIs.
• Collaborate closely with product and engineering teams to define, design, and ship new features.
• Contribute ideas to improve product performance, functionality, and user experience.
• Take full ownership of deliverables — from architecture to deployment.
• Work across the stack when needed, supporting frontend integration.
• Participate in technical discussions, bringing both depth and perspective to product decisions.
• Build and maintain AI agents or AI‑driven features, ensuring reliability and continuous improvement.

What We’re Looking For

• 5+ years of backend development experience, ideally in fast‑paced startup environments.
• Strong proficiency in Python (experience with frameworks like Django, Flask, or FastAPI).
• Experience designing and maintaining AI agents or AI‑driven systems.
• Solid understanding of system design, debugging, and scalable architecture.
• Strong sense of ownership and accountability for your work.
• Advanced English communication skills (you’ll interact daily with your teammates in English).
• Collaborative mindset. Open, curious, and comfortable in an agile, fast‑changing environment.
• Passion for building great products, not just writing code.

Nice to Have

• Experience working across the stack (some familiarity with frontend technologies).
• Previous experience in early‑stage startups.
• Familiarity with MLOps, cloud infrastructure (AWS, GCP, Azure), or data pipelines.

What We Offer

A chance to join a high‑growth US startup shaping the future of AI‑driven products.

A culture that values autonomy, creativity, and speed over process.

Collaborative, low‑ego environment focused on building together.
