AI Engineer

San Francisco, CA Full Time
POSTED ON 11/25/2025 CLOSED ON 12/24/2025

What are the responsibilities and job description for the AI Engineer position at Fathom?

About Fathom:

We think it’s insane that so many people and businesses rely on notes to remember and share insights from their meetings.

Notes are time-consuming and stressful to create while trying to hold a conversation. Even when done well, notes are a poor solution compared to hearing something first-hand.

We started Fathom to rid us all of the tyranny of note-taking, and people seem to really love what we've built so far:

🥇 #1 Highest Satisfaction Product of 2024 on G2

🔥 #1 Rated on G2 with 4,500 reviews and a perfect 5/5 rating

🥇 #1 Product of the Day and #2 AI Product of the Year

🚀 Most installed AI meeting assistant on both the Zoom and HubSpot marketplaces

📈 We’re hitting usage and revenue records every week

We're growing incredibly quickly, so we're looking to grow our small but mighty team.

Role Overview:

As an AI Engineer at Fathom, you'll be hands-on with LLMs, prototyping and refining our features. Your work will directly shape our product by generating practical specifications that steer our engineering team towards impactful updates and novel capabilities.

This role is a bit of a hybrid of engineering // analytics // product management // research. It would suit someone already in an AI Engineering role as well as software engineers or data scientists that have gone deep into building AI features.

This role is open to the US only, and does require 3 days per week in-office in San Francisco, California.

What you’ll do:

  • By 30 Days, you will have
    • Upgraded existing features to be smarter and/or faster by combining your prompt engineering experience with the latest available models.
    • Improved or created new evaluations for our existing features.
  • By 90 Days, you will have
    • Prototyped new AI features that address valuable use cases.
    • Fine-tuned models for our specific needs.
    • Developed new processes to speed-up how we migrate to new AI models.
Show off in your application! (Important)

When applying, include a quick demo of something you made with LLMs that you’re really excited about. It should showcase your fit for the role. Include it in any form you’d like (such as a link to a short video or a repo).

Requirements:

Hard Skills:

  • Experience with prompt engineering – able to prompt LLMs to achieve outstanding and reliable outcomes.
  • Proficient in Python and able to hack together end-to-end prototypes.
  • Foundational analytics (able to manipulate data in Python or SQL).

Soft Skills:

  • Attention to detail, and a high level of scrutiny for impactful applications of LLMs.
  • Curiosity-driven and pragmatic with a focus on delivering results.
  • A generalist mindset with the ability to dive deep into a wide range of challenges.
  • Resilience and an ability to grind through complex problems.
  • Openness to disagreement and commitment to decisions once made.
  • Strong collaborative skills, with the ability to explain complex insights in an accessible manner to both technical and non-technical audiences
  • Independence in managing one’s workload and priorities

Nice to Have:

  • Previous experience in fine-tuning LLMs is highly desirable.

What You'll Get:

  • A career-defining opportunity to work on LLM features at this pivotal time.

  • A supportive environment that encourages innovation and personal growth.
