About the Opportunity
We are partnering with an ambitious, venture-backed AI-native startup that is reimagining how businesses identify customers, automate commercial operations, and scale their growth.
Operating at the intersection of artificial intelligence, commerce, and business automation, the company is developing a proprietary technology platform designed to modernize a traditionally underserved multibillion-dollar industry.
The founding team is seeking an exceptional Senior Full-Stack Engineer to take substantial ownership of the company's core software platform and help shape its technical future.
This isn't a traditional senior engineering position where you'll simply execute tickets or maintain existing systems.
You'll work directly with the founders, influence product strategy, make critical architectural decisions, and personally build the technology powering the business.
The longer-term opportunity is particularly compelling: The founders envision this hire potentially progressing into the CTO position as the organization evolves.
For an ambitious engineer who enjoys building, thrives in early-stage environments, and wants meaningful ownership, this is an opportunity to make an outsized impact.
What You'll Be Doing
End-to-End Product Ownership
Own the architecture, development, deployment, and evolution of the company's core software platform.
Build scalable, production-grade applications spanning frontend, backend, and database layers.
Take complete ownership of important product initiatives, from identifying problems to delivering working solutions.
Make independent technical decisions while balancing speed, maintainability, scalability, and business impact.
Full-Stack Engineering & System Design
Develop intuitive, high-performance web applications using modern JavaScript frameworks.
Build backend services, APIs, data pipelines, and integrations with external platforms.
Design robust relational database schemas and normalize complex, unstructured business data.
Develop systems supporting customer acquisition, workflow automation, sales operations, and order management.
Build integrations with third-party enterprise applications, including ERP and related operational systems.
AI-Native Development
Leverage modern AI-assisted engineering tools, including Cursor, Devin, and similar technologies, to accelerate development.
Explore opportunities to incorporate intelligent automation and AI-driven workflows into the product.
Continuously improve engineering processes, development velocity, and product quality.
Product Strategy & Cross-Functional Collaboration
Collaborate directly with company founders and commercial teams to translate business needs into technical solutions.
Gather feedback from actual platform users and rapidly turn insights into product improvements.
Influence the product roadmap, technical priorities, and long-term platform architecture.
Help establish engineering practices and contribute to the team's technical direction as the company grows.
