LLM Engineer   $200,000+ Offers For Graduates $200,000+ Offers For Graduates 

Description

Gauntlet is a selective, fully funded 10-week fellowship designed for experienced engineers seeking to accelerate their careers by demonstrating their ability to build and deploy production-grade AI systems under real-world conditions. Fellows ship work weekly, collaborate with seasoned operators, and gain direct access to founders, CTOs, and hiring partners.

Participants in our most recent cohort earned 300+ first-round interviews with hiring partners. We aim for 100% of graduates to receive job offers from our partner network, with minimum starting compensation of $200,000.

The fellowship spans 10 weeks: 3 weeks conducted remotely, then 7 weeks onsite in Austin, Texas. Fellows must be prepared for a high-intensity commitment (80–100 hours/week) engineered to maximize learning velocity, performance signal, and career advancement.

Program Outcomes:

  • 10+ deployed AI applications delivered during the fellowship
  • Access to Gauntlet's alumni and hiring partner network
  • Graduates receive job offers of $200,000+ from hiring partners

If you ship quickly, perform under pressure, and want your work — not your resume — to define your next opportunity, apply now.

What you will be doing

  • Deliver production-ready AI applications weekly under strict deadlines
  • Work with modern AI-first workflows including agents, tool use, evals, retrieval, and deployment
  • Compete and collaborate with elite engineering talent in a high-feedback setting
  • Present your work directly to founders, CTOs, and hiring partners
  • Convert real briefs into scoped, reliable, and deployable systems

What you will NOT be doing

  • Spending weeks on tutorials, theory, or passive study without shipping deliverables
  • Creating demos that are never exposed to real usage or evaluation
  • Refining resumes and portfolios rather than building and deploying functional systems
  • Attending weeks of lectures and coursework before writing real code

Key responsibilities

Build and ship production-grade AI systems on a weekly cadence, converting demonstrated engineering performance into $200K+ career outcomes via Gauntlet's hiring partner network.

Candidate requirements

  • 3+ years of professional engineering experience (or equivalent demonstrated ability)
  • Have independently designed, implemented, and deployed at least one working software system to production or active users
  • High responsiveness to feedback and extreme execution intensity
  • Authorized to work in the U.S. without visa sponsorship
  • Willing to commit to 80–100 hour weeks and relocate to Austin for 7 weeks
