ML/AI Engineer

At Rillet, we’re changing the way high-growth companies make financial decisions. Our goal is to make zero day close a reality. No more reporting 10 days after quarter end, report day ZERO. Rillet is a next-gen accounting platform purpose built to automate end-to-end accounting workflows. In practical terms, information from CRM, billing, AP, payroll, etc. is synced instantaneously with Rillet, and 93% of journal entries are booked without human intervention. CEO, CFO, and finance teams can finally focus on making impactful financial decisions, while leaving Rillet run the numbers.

Rillet’s an early stage startup with a big vision. We raised $38.5m from Sequoia, First Round Capital, Creandum and Susa Ventures. We're looking for people with passion and grit who strive for excellence.

We’re looking for a machine learning engineer to work on the core systems that power Rillet’s AI-driven workflows. You’ll join a growing engineering team and work closely with the CTO, product, and design to build industry-defining accounting and finance software. The role is remote first, with opportunities to travel for team events.

• Help define Rillet’s ML and AI direction for years to come.
• Collaborate closely with product managers, engineers, designers, and finance experts to define ML solutions, not just build them.
• Deeply understand user problems and find the best methodology to solve them.
• Develop automated pipelines and processes to train and evaluate models.
• Integrate ML/AI models into production systems and ensure their scalability, reliability, and performance.

• 3+ years of relevant professional experience in product-driven tech companies.
• Strong Python experience (numpy, pandas, sklearn, pytorch, etc.) across ML techniques and backend engineering.
• Experience with LLM-based agent frameworks.
• Can work both independently and collaboratively in a small team.
• Enjoy finding practical solutions to real user problems without compromising on quality.
• Have a passion for learning and sharing your expertise with others.
