About the Senior Full Stack Software Engineer Role at Robert Half

Join Robert Half as a Senior Full Stack Software Engineer in Englewood Cliffs, New Jersey, where you'll take full ownership of critical systems powering operations, revenue, and customer experiences. This full-time position is perfect for a reliable developer who prioritizes shipping working software over hype, collaborates seamlessly across teams, and thrives in real-world constraints. We're not seeking a '10x developer'—we want someone who finishes tasks, documents thoroughly, and respects deadlines. Success means features ship on time, progress is visible weekly, estimates are reliable, systems are team-readable, and no one becomes a bottleneck.

In this role, you'll work on production systems using modern stacks like React, Next.js, Node.js, TypeScript, and relational databases such as PostgreSQL or MySQL. Familiarity with Rust is a bonus, as is experience integrating with Stripe, shipping APIs, and messaging systems. Located in the vibrant Englewood Cliffs area, this position offers a chance to impact high-stakes environments while enjoying a supportive culture at Robert Half.

Key Responsibilities

Delivery & Execution

• Deliver production-ready features aligned with milestones and acceptance criteria.
• Break complex work into small, testable, demoable increments for consistent progress.
• Communicate risks early, adjusting plans based on reality rather than optimism.

Front-End Development

• Build responsive front-end applications with React or Next.js.
• Integrate components cleanly with backend APIs, prioritizing usability and clarity.

Back-End & Systems Integration

• Develop and maintain backend services and APIs using Node.js and TypeScript (Rust preferred).
• Integrate third-party services including Stripe for payments, shipping providers, and messaging systems.
• Manage inventory, asset tracking, and operational data systems.

Data & Infrastructure

• Design relational databases with PostgreSQL or MySQL.
• Implement safe, understandable data migrations.
• Enhance logging, monitoring, and observability for robust production systems.

Collaboration & Accountability

• Partner with operations, product, and leadership teams beyond just engineering.
• Document APIs, assumptions, and behaviors comprehensively.
• Engage in code reviews focused on clarity and maintainability.
• Embrace feedback constructively without defensiveness.

Required Qualifications

To excel as our Senior Full Stack Software Engineer, bring proven experience in full-stack development with a track record of reliable delivery. Key qualifications include expertise in React/Next.js for front-end, Node.js/TypeScript for backend, and databases like PostgreSQL/MySQL. You should demonstrate skills in API integrations (Stripe, shipping, messaging), data migrations, and observability tools. Soft skills matter: strong communication for cross-team collaboration, meticulous documentation habits, and a pragmatic approach to estimates and risks. A bachelor's degree in Computer Science or related field is preferred, along with 5+ years of professional experience. Rust knowledge is a plus for advanced systems work.
