Senior Software Engineer / AI Agent Data Platform / Onsite at TrustIn
This company is at 8-figure revenue, growing fast, and about to raise a $20–30M Series A. They’re looking for a senior infrastructure engineer who wants outsized impact from day one on a tight-knit, talent-dense team.
WHAT YOU'LL DO:
• Design and build the foundational systems that power all of our data generation platforms, human-in-the-loop pipelines, and evaluation infrastructure — the layer everything else depends on.
• Build distributed systems capable of processing large-scale datasets and high-throughput workloads — designed to scale with a company on a hockey-stick trajectory.
• Work closely with vertical-focused engineering teams to give them the platform and services they need to build quickly — your job is to make everyone else faster.
• Lead on best practices for system design, deployment, and reliability — and mentor the junior engineering team in a culture that's collaborative, fast-moving, and high-trust.
WHAT WE'RE LOOKING FOR:
✓5–8 years building and owning core infrastructure at a high-growth tech company
✓Proven track record designing scalable distributed systems that handle large-scale data and high-throughput workloads
✓Comfortable mentoring junior engineers and raising the bar through your own work and standards
✓Excited to work in a fast-moving startup environment with open communication and rapid iteration
✓Experience in human-in-the-loop data systems or AI/ML infrastructure is a strong plus
