Semi-Senior Software Engineer - Powering the people who bet on the future

What We're Actually Building

We're engineering decision-making infrastructure for some of the world's top 50 VC firms (seriously—though we can't name-drop for confidentiality reasons). When elite investors evaluate whether that AI biotech startup is the next $10B company or just impressive slide decks, our systems cut through the noise.

The reality: We build AI-powered dealmaking intelligence for private capital. Custom algorithms that surface signal from noise, automated workflows that compress weeks into hours, and data pipelines that actually make sense of the chaos.

What you'll do: Write backend systems that matter. Build features that influence how billions get allocated. Ship code that helps identify the next generation of category-defining companies.


Why Loop3

💡 Impact Beyond Pixels: Your code moves markets. The features you build help allocate capital to companies that create jobs, fund breakthroughs, and shape industries. Our clients are the people who funded the unicorns you use daily.

🚀 Learn Bleeding-Edge Tech: Modern backend architecture meets AI/ML pipelines and financial data at scale. Real-time market signals, multi-source data reconciliation, AI agents analyzing investment opportunities—the kind of problems most engineers never get to touch.

🎯 Pure Meritocracy: Can you ship excellent software that solves hard problems? That's all we care about. No politics, no theater, just engineering excellence and results that speak for themselves.

🔥 High Agency Environment: We don't wait for permission. We see problems and fix them. We build, ship, learn, and iterate. Every loop makes us better. Progress is our perfection.


What You'll Build

Our stack: Node.js/TypeScript, Azure/GCP/AWS (Lambda, API Gateway, S3, EC2, SQS, RDS, EventBridge, AppRunner), SST/Terraform, Next.js, React, SQL/NoSQL, Python for AI & ML, Snowflake.

But honestly—if you think in system design and ship clean code, the stack is just details.
