Staff Machine Learning Engineer (Search)

Meet Fetch Engineering: 

At Fetch, we are passionate about solving challenging problems and embracing ambiguity. Our engineering philosophy promotes adaptability and innovation over rigid adherence to rules. Our engineers thrive in complex environments, making well-informed decisions even in uncertain situations. We seek out the necessary information and focus on action and impact, while consistently upholding high technical standards. In this role, you will be a technical leader, shaping best practices to build world-class, user-facing technology. You will mentor fellow engineers, fostering technical growth and collaboration within the team. As a hands-on leader, you will actively contribute to the codebase and deliver features alongside your team.

About the Role:

As a Staff Machine Learning Engineer specializing in Search, you will design, build, and implement NLP-based systems that have a direct impact on the user experience. ML-based search models are used at Fetch to improve our ability to understand receipt data as well as power in-app search. When our search models get better, users get more points and Fetch earns more revenue!

Beyond technical implementation, you'll serve as a “tech lead of tech leads”, which will put you in a position to influence the direction of multiple ML projects within this domain. Your skills and experience will level up the people around you and inform the vision of the Machine Learning team as Fetch deepens its investment into ML.

• Experience with large datasets, data pipelines, and deploying ML models to production environments.
• Deep understanding of both traditional and vector-based search algorithms (from TF-IDF to HNSW and everything in between)
• Excellent communication skills and the ability to translate technical concepts into business impact.
• Ability to implement online/offline evaluation strategies to compare iterations of models.

Bonus Points:

• Experience building search engines or Entity Resolution models.
• Experience implementing vector databases (i.e. FAISS, Voyager, Pinecone, etc)
• Experience with NLP tasks like fine-tuning LLMs, RLHF, prompting, and semantic search
• Prior experience working in high-growth tech environments.
