We are partnered with a high-growth, AI software company that helps large enterprises build and deploy tailored solutions to their most complex operational challenges. The company is well-funded, scaling rapidly, and already working with recognised organisations across a number of industries.

The Role

As a Python Software Engineer, you'll sit at the intersection of engineering and customer impact - working closely with clients to understand their hardest problems and building tailored software solutions to solve them.

• Building applications that leverage large structured and unstructured datasets
• Collaborating with ML engineers to integrate and deploy AI/LLM-based capabilities
• Ensuring reliability, security, and compliance in production systems
• Occasional travel for client implementation work (~10% of your time)

The Ideal Candidate Will Have

• A strong track record of delivering real-world outcomes with code
• Proficiency in Python and/or TypeScript
• Experience building data-intensive applications in a production environment
• The ability to work independently and own outcomes autonomously
• Strong communication skills - comfortable working with both technical and non-technical stakeholders
• Experience with or exposure to ML/LLM-based solutions
• Experience with React or Spark is a plus

Why Join

• Competitive salary + equity (stock options)
• Comprehensive benefits including health, dental, vision
• Direct exposure to leadership and real influence over technical decisions
• Opportunity to build a category-defining AI platform from the ground up
• Small, high-performing team where your contributions have direct impact

Fast-moving, customer-focused, and high-impact - this role is for engineers who want to build serious software that solves real problems.
