## Description

We are looking for a highly experienced, hands-on full-stack engineer to become a foundational member of our engineering team.
You will join and help lead a team with end-to-end ownership of a web-based database application at the center of our interactions with experts and clients. Your work will span technical design, backend and database development, third-party API integration, front-end delivery, deployment, and production support.
This is a high-autonomy role for an engineer who enjoys working close to the business. You will partner directly with product, operations, and other frontline stakeholders to review and solve high-priority software problems, evaluate opportunities based on return on investment, and deliver practical software that improves how our teams operate.
You will also help establish the technical practices and operating standards for a growing engineering organization. Over the following six months, you will participate in interviewing, hiring, and mentoring additional engineers joining the team.

What You'll Do

 + Take full ownership of "the how" regarding major product features, from architectural approach and technical design through implementation, quality assurance, deployment, monitoring, and production support.
 + Design, build, and maintain reliable backend services using Java and Spring.
 + Maintain and evolve our database architecture, data models, and queries to support performance, reliability, and future scale.
 + Build and harden front-end features to production quality, collaborating with product and using AI-assisted design and development tools where appropriate.
 + Work directly with product, operations, and front-line team members to understand workflows, identify inefficiencies, and design effective software solutions.
 + Develop a strong understanding of our fast-moving business and help prioritize technical investments based on customer impact, operational value, and ROI.
 + Use AI-assisted coding tools, such as Codex, Claude Code, or similar platforms, as a regular part of your development workflow while maintaining high standards for testing, review, security, and maintainability.
 + Deploy, monitor, and support applications running on AWS, including cloud maintenance and security in accordance with ISO 27001 and 27701 frameworks, contributing to the reliability and operational maturity of our production environment.
 + Participate in a shared production-support rotation during New York business hours, initially in partnership with our New York-based engineer.
 + Help design the incident-response, monitoring, documentation, and on-call practices that the growing engineering team will use.
 + Contribute to technical architecture, engineering standards, development processes, and decisions about when to improve existing systems versus introduce new technologies.
 + Participate in interviewing and selecting backend, frontend, and platform engineers as the team grows.
 + Provide technical guidance, mentorship, and thoughtful code and design reviews to other engineers., + Build a strong understanding of the application, its architecture, and the business workflows it supports.
 + Take ownership of meaningful product features across the backend, database, and front end.
 + Establish trusted working relationships with our New York-based engineer and Product and Operations stakeholders.
 + Improve the reliability, maintainability, monitoring, and documentation of the production system.
 + Help establish practical production support and incident-response practices.
 + Use AI-assisted development tools effectively while maintaining clear accountability for code quality and system behavior.
 + Contribute to the hiring and onboarding of the engineers who will form the next stage of the team.
 + Help create a technical foundation that allows the engineering organization to grow without losing speed, quality, or connection to the business.
