About the role

We are seeking a Python Developer to join our team and help build the next generation of AI solutions. This is a unique opportunity to be a key technical contributor in a fast-paced, innovative environment where you'll wear many hats and have significant impact on our product and engineering culture.

As a Python Developer, you'll work across the entire technology stack from backend services and data pipelines to infrastructure and deployment. You'll collaborate closely with the engineering team to architect, build, and scale our micro-services based platform while maintaining high code quality and operational excellence, utilising AI to maximise software development productivity.

About Prolo

Prolo is building an AI-powered procurement platform for the construction industry, which is one of the oldest and least digitised sectors in the world. The core system ingests unstructured purchase orders and transforms them into structured materials data, integrating with a network of suppliers and logistics partners to automate quoting, sourcing, and fulfilment workflows.

What We're Building

We're building a sophisticated AI platform that leverages graph databases, machine learning, and modern cloud infrastructure to deliver intelligent procurement and customer service solutions. Our stack includes:

• Backend Services: Python 3.13, FastAPI, async micro-services architecture
• Data Layer: Neo4j graph database, PostgreSQL, complex data modelling
• AI/ML: OpenAI integration, semantic search, conversational agents, unstructured data analysis and extraction
• Infrastructure: AWS (Lambda, ECS/EKS, API Gateway, S3)
• DevOps: Terraform, GitHub Actions, Helm, Infrastructure-as-Code
• Data Science: Graph analytics, data pipelines, ETL workflows, Jupyter notebooks

Experience

• 5+ years of professional software engineering experience
• Strong proficiency in Python (3.10+) with deep understanding of async programming
• Experience with Poetry or similar Python dependency management tools
• Experience building RESTful APIs and micro-services
• Solid understanding of database design and optimisation (both SQL and NoSQL)
• Experience with graph databases (Neo4j preferred) or willingness to learn quickly
• Knowledge of API design principles, data validation, and serialisation
• Experience with AWS Lambda and serverless architectures

What We Offer

• Impact: Direct influence on product direction and technical decisions
• Growth: Opportunity to work across the entire stack and learn new technologies
• Ownership: Take ownership of features from conception to deployment
• Flexibility: Hybrid, remote-friendly work environment
• Equity: Meaningful equity stake in the company
• Learning: Access to cutting-edge technologies and challenging problems

Note: Prolo is a startup with a small engineering team, which means you'll be expected to be versatile, proactive, and comfortable with ambiguity. If you're excited about building something from the ground up and working across the entire technology stack, we'd love to hear from you.
