Job Overview

Lemon.io, a global remote developer marketplace that connects vetted engineers with hand-picked startups in the US and Europe, is hiring a Senior Python & LLM/AI Engineer for remote work. This role focuses on backend development and integrating modern AI/LLM technologies into scalable digital products.

As part of the backend engineering team, you will design, build, and deploy production-grade systems using Python and LLM-related frameworks. You will work with modern cloud infrastructure, contribute to core architecture decisions, and apply machine learning and AI integration where required.

This opportunity is ideal for experienced developers who enjoy remote work flexibility, technical challenge, and collaboration across global teams.

Why This Role Is Unique

Unlike static in-house engineering jobs, this role expands your exposure to multiple startup projects that require Python development and AI/LLM expertise.

Lemon.io’s matching platform pairs you with opportunities aligned to your skills and preferences.

You won’t be limited to a single team; instead, you’ll work on high-impact applications and systems that leverage:

Advanced backend Python logic
LLM and AI model integration
Cloud infrastructure and API services
Data pipelines and automated workflows

The role prioritizes technical depth and autonomy — key factors for senior engineers seeking remote, high-growth opportunities.

Key Responsibilities

As a Senior Python & LLM/AI Engineer, you will:

Design, implement, and maintain backend services using Python
Integrate LLM/AI components to support intelligent features
Build scalable APIs and backend infrastructure
Participate in architecture discussions and engineering planning
Collaborate with product leaders, designers, and other engineers
Ensure code quality with tests, code reviews, and best practices
Optimize performance and reliability for production systems

This role expects a strong engineering foundation with autonomy in managing technical deliverables and architectural decisions.

Required Experience and Skills

To excel in this position, you should have:

5+ years of professional experience in Python development
Strong backend engineering skills with REST APIs and modern frameworks
Hands-on experience with AI or LLM integrations (e.g., transformers, embeddings)
Cloud platform experience (AWS, GCP, or similar)
Solid understanding of scalable system design
Excellent problem-solving and analytical skills
Ability to work independently in a remote environment

Bonus points if you have worked with microservices, async frameworks (FastAPI, Django, Flask), and production-grade ML/AI tooling.
