Mern Stack Developer

## About Tequity Tequity builds high-velocity engineering teams for startups and growth-stage companies that need execution without compromise. We operate as an extension of our clients' core engineering organizations, shipping production-grade systems with speed, accountability, and engineering rigor. We are looking for engineers who think beyond tickets, communicate clearly, and take ownership of outcomes end-to-end. You can read more about us here: https://www.tequity.tech/ ## Key Responsibilities ### Full Stack Development - Build scalable, production-grade applications using Next.js, React, Node.js, and Nest.js. - Design backend systems, APIs, and distributed services with scalability and maintainability in mind. - Contribute across frontend, backend, infrastructure, and adjacent systems as needed. - Work comfortably across Python and Go for supporting services, automation, or AI workflows. ### AI-Native Engineering - Build custom AI agent workflows using tools such as Codex, Claude Code, or equivalent platforms. - Design asynchronous AI-assisted workflows that can operate independently with minimal supervision. - Treat AI systems as execution accelerators while retaining engineering judgment and architectural ownership. - Continuously evaluate and improve developer productivity using AI tooling and automation. ### Engineering Quality & Testing - Write comprehensive automated tests covering edge cases, failure modes, and negative scenarios. - Use mutation testing tools such as Stryker (or equivalent) to validate test quality beyond coverage metrics. - Design systems with resilience, observability, and production reliability in mind. - Document technical trade-offs and implementation approaches before building non-trivial systems. ### Production Ownership - Build systems that are scalable, observable, and maintainable in production. - Design for operational reliability, failure recovery, and long-term maintainability. - Participate in debugging, incident resolution, and production support when needed. - Maintain strong engineering hygiene across code quality, PR reviews, documentation, and delivery processes. ### Communication & Stakeholder Management - Communicate technical concepts clearly to founders, PMs, and non-technical stakeholders. - Write concise, actionable documentation and technical recommendations. - Recommend better technical approaches when appropriate, even if they differ from the original request. - Push back respectfully on poor technical decisions with clear written reasoning. - Operate independently under pressure while maintaining sound engineering judgment. - Earn trust through clarity, reliability, and delivery consistency. ## Required Skills & Experience ### Technical Skills - Strong expertise in React-based frameworks, especially Next.js. - Expert-level Node.js experience with Nest.js as the preferred backend framework. - Strong understanding of scalable frontend and backend architecture. - Comfortable working with Python and Go in supporting or adjacent systems. - Strong API design, database design, and system design fundamentals. - Experience building and maintaining production-grade applications. ### AI & Workflow Automation - Hands-on experience working with AI coding assistants, agents, or workflow automation tools. - Ability to build custom AI-powered engineering workflows and productivity systems. - Strong understanding of where AI improves execution versus where engineering judgment is required. ### Testing & Engineering Discipline - Strong automated testing practices including edge-case and failure-mode testing. - Familiarity with mutation testing tools such as Stryker or equivalent. - Experience maintaining high-quality engineering standards in fast-moving environments. ### Communication & Ownership - Strong written communication and documentation skills. - Comfortable working independently and making engineering decisions under pressure. - Ability to explain technical concepts clearly to non-technical stakeholders. ## What We Look For - **Integrity**: Surfaces risks and blockers early. Delivers on commitments with transparency and accountability. - **High Standards**: Writes production-quality code with reliability and maintainability in mind. Maintains strong engineering discipline even under delivery pressure. - **Accountability**: Owns outcomes, stability, and delivery quality — not just effort. Measures success by what ships, performs, and remains stable in production. - **Customer Focus**: Treats the client's product and engineering challenges as their own. Focuses on practical solutions that create measurable impact. - **Learning Mindset**: Quickly adapts to new stacks, frameworks, AI tooling, and engineering workflows. Continuously improves both personal systems and team engineering practices. ## Why Join Tequity? - Work on modern AI-enabled engineering problems with high ownership. - Build products and platforms used by fast-growing global clients. - Strong engineering culture focused on quality, speed, and accountability. - Opportunity to shape engineering standards, AI workflows, and scalable systems from the ground up.
