Senior Full Stack Engineer

As a Senior Full-Stack Engineer at Cyvl, you will play a leading role in delivering intuitive, performant, and scalable applications for our customers. You’ll be responsible for designing and building new user-facing features with a strong emphasis on elegant, component-driven React development. While the role leans front-end, you'll be expected to contribute to and maintain APIs, services, and data pipelines across our backend, including direct interaction with Postgres and Supabase. This position offers the opportunity to work closely with our engineering and product teams to shape the future of our platform as we grow rapidly and serve new customers.

Your Responsibilities:

• Lead the design, development, and deployment of front-end features using React and modern JavaScript/TypeScript frameworks.
• Collaborate with design and product teams to bring smooth, accessible, and responsive interfaces to life.
• Build, document, and maintain scalable APIs using Node.js and Supabase.
• Own full-stack features from conception to deployment—contributing across the stack as needed.
• Work with Postgres to design, query, and optimize data models and workflows.
• Contribute to architectural decisions and code reviews across the engineering organization.
• Mentor junior engineers and elevate the overall engineering bar.
• Partner with QA and DevOps to ensure robust, testable, and observable systems.

Requirements:

• 5+ years of professional experience in a full-stack or front-end focused engineering role.
• Proficiency in React and front-end frameworks (Next.js, Vite, etc.) with a focus on clean, reusable components.
• Expertise in Python and modern Python package management tools like Poetry and UV
• Strong command of JavaScript/TypeScript and modern front-end development practices (hooks, context, etc.).
• Experience designing and consuming RESTful APIs and backend services.
• Comfort working with relational databases, particularly Postgres.
• Experience deploying and managing serverless environments and platforms like Supabase or Firebase.
• Strong Git workflow knowledge and experience with CI/CD pipelines.
• Ability to work cross-functionally in a fast-paced, collaborative team environment.
• Experience with cloud infrastructure (e.g., AWS, Vercel, Netlify).

What We Offer:

• Competitive salary and equity package
• Comprehensive health, dental, and vision insurance
• Opportunities for professional growth and development
• A collaborative and innovative work culture with a tight-knit team of ~20 employees.
