About the Role
- We're hiring an exceptional Staff or Principal Architect to lead the ground-up design and build of Maverick-our next-generation, multi-tenant SaaS platform for AI-powered financial intelligence and workflow automation.
- This is a rare true Greenfield opportunity: architect, build, and launch a production-ready platform from scratch within 3 months.

- Hands-On Development (25%) - Contribute high-impact code, drive engineering excellence, and accelerate execution velocity.
- Production Readiness (15%) - Ensure infrastructure, security, reliability, and DevOps readiness for a 3-6 month launch timeline.
- 12+ years of software engineering experience, including 5+ years in architect roles
- Proven success in architecting and launching Greenfield multi-tenant SaaS platforms
- Product development experience with aggressive timelines
- Expertise across frontend, backend, data, and cloud infrastructure (AWS preferred)
- Strong experience with EKS/ECS, PostgreSQL, enterprise Auth, and high-performance systems
- AI/LLM architecture experience: Lang Graph/Lang Chain, agent-based systems, OpenAI/Anthropic integrations
- Strong technical leadership and communication skills
- Financial services experience, startup/rapid growth background, security/compliance expertise, and cost optimization skills.
