The posting
You'll be Employee #3, working directly with us to build technology that will modernize the backbone of global commerce. This isn't incremental improvement—this is category creation.
The Technical Challenge:
- Design and implement transformer architectures specifically optimized for COBOL→Java/Python translation
- Build real-time code analysis engines processing millions of lines with sub-second latency
- Create enterprise-grade AI pipelines handling Fortune 100 codebases with zero tolerance for error
- Architect distributed systems supporting concurrent modernization of 50+ million line codebases
What We Demand (Non-Negotiable)
Technical Mastery:
- 8+ years building production AI/ML systems at scale (not research, not prototypes—systems handling real user traffic)
- Deep expertise in transformer architectures, fine-tuning, and custom model development
- Proven track record optimizing inference for enterprise workloads (sub-100ms response times)
- Systems engineering excellence: distributed computing, microservices, cloud-native architecture
- Battle-tested experience with PyTorch/TensorFlow, CUDA optimization, and model deployment
Founding DNA:
- 0→1 product builder: You've taken ideas from whiteboard to millions of users
- Technical leadership: You've hired and led engineering teams of 10+ engineers
- Ownership mentality: You think like an owner because you've been one
Enterprise Credibility:
- B2B product intuition: You've built products that CFOs and CTOs actually buy and deploy
- Performance obsession: You've optimized systems handling billions of transactions with 99.99% uptime
What Sets You Apart from 99.9% of Engineers
- You've shipped AI products that generated $10M+ in revenue
- You can debug transformer attention mechanisms as easily as you debug distributed systems
- You've led technical due diligence for VC firms or been the technical founder VCs bet on
- You speak both languages: You can explain neural architecture to PhD researchers and ROI to enterprise buyers
- You have pattern recognition from seeing multiple 0→1 journeys and know what actually scales
The Opportunity
Immediate Impact:
- Technical co-founder role with significant equity upside
- Direct partnership with CEO on product strategy and technical vision
- Ownership of entire AI engineering organization as we scale to 100+ engineers
- Platform architecture decisions that will define a multi-billion dollar market
Market Timing:
- Zero real competition in AI-powered COBOL modernization
- Massive tailwinds: Every enterprise needs this, regulatory pressure increasing, COBOL talent retiring
Financial Upside:
- Equity package designed for 10x+ returns based on current traction. (2% equity vesting in 4 years)
- Fast-track to CTO as we scale through Series B and beyond
- Life-changing wealth creation opportunity in a category we're defining
What We Offer Beyond Compensation
- Unlimited PTO (because we hire people who don't need to be managed)
- $5K annual learning budget for conferences, courses, and technical development
- Top-tier health/dental/vision with 100% company coverage
- Latest hardware: M3 MacBook Pro, multiple 4K monitors, whatever you need to be productive
- San Francisco office in SOMA with optional remote flexibility
The Interview Process (Designed for Busy Founders)
- 30-minute technical screen with our CEO (we respect your time)
- Technical deep-dive (4 hours): Architecture design + live coding + system design
- Product strategy session (2 hours): How would you scale our AI platform?
- Reference calls with previous co-founders/technical leaders you've worked with
- Final conversation about equity, role scope, and mutual fit
Apply Only If:
- You have concrete examples of AI systems you've built that handle enterprise workloads
- You can start within 30 days (we're moving fast and need someone who can too)
- You're excited about legacy modernization as a massive market opportunity, not just another AI application
