Job description
From LatamCent’s job post, as they wrote it.
The Opportunity
You'll join a small frontier AI team inside a fast growing B2B SaaS company, where the job is figuring out what new models can actually do and turning that into agents customers use. In your first 90 days you'll set your own research agenda and build the benchmarks the team trusts; within a year your experiments will be shaping the product. If you like owning hard, open problems with no backlog and real impact, this is that seat.
Read the full description
What You'll Own
· Decide which new models, papers and techniques are worth betting on, and prove it with data
· Build agents on frontier APIs that understand unfamiliar software and complete real business tasks
· Create the eval and benchmark system that tells the team when an agent truly got better
· Turn agent failures into fixes by digging into where and why things break
· Ship frontier prototypes and demos that leadership shows to customers, then hand the winners to engineering
· Be the team's public voice on what you learn: blog posts, talks and short videos
What We're Looking For
· 5+ years at startups owning technical outcomes (3+ considered for standout profiles)
· Hands on work building multi step agents with frontier LLMs (tool use, orchestration)
· A track record of AI products or systems that reached real users
· Rigorous experiment design: baselines, eval sets, telling signal from noise
· You move work forward on your own and raise blockers early, without needing structure
· AI tools are part of your daily workflow, and you can name what you use for what
· Strong spoken and written English for presentations, travel and writing
· Open to an independent contractor setup paid in USD
Nice to Have
· Time at a top AI lab, or experience training agents in real environments
· RL, post training or fine tuning experience
· Published research, benchmarks, open source work or technical writing
· An active voice in the AI community (posts, talks, GDE or similar)
Tools and Stack
Python, frontier model APIs (Anthropic, OpenAI, Gemini), agent and eval tooling of your choice. The team has no fixed stack and builds its own when that works best.
Details
· Location: Hybrid, São Paulo, Brazil (3 days/week on site); relocation support available
· Time Zone: Brazil (BRT)
· Salary: $6,650 to $7,500/month USD ($80K to $90K/year)
· Equity: Included
· Type: Contract
