About The Role

We’re launching a new D2C product in the LegalTech/Utilities space and are looking for a Middle Full-Stack Engineer who’s hungry to build, learn, and grow alongside a high-performing team. You’ll be a key contributor to product development, working across the stack and collaborating closely with senior engineers and product leads.

This role is perfect for someone who is technically strong, highly motivated, and looking to take the next step in their career by owning meaningful parts of a fast-growing product. You’ll work in a startup-style environment where speed, pragmatism, and a builder mentality matter.

If you’re looking for comfort and predictability, this might not be your ideal role. But if you’re excited by challenge, ownership, and the opportunity to grow fast, read on.

Key Responsibilities

  • Build and ship core product features using Next.js, React, and Nest.js.
  • Own specific product modules end-to-end, with mentorship and support from senior engineers.
  • Implement responsive, accessible UIs using TypeScript, TailwindCSS, and design system guidelines.
  • Develop scalable backend services and APIs using Nest.js, PostgreSQL, and Redis.
  • Ensure code quality through regular code reviews, testing, and performance optimizations.
  • Work in a fast-paced, iterative development environment with rapid MVP cycles.

Qualifications

  • 3–5 years of hands-on, production experience building full-stack applications using React, Next.js, TypeScript, and TailwindCSS.
  • 2+ years of backend development with Nest.js (or similar Node.js frameworks), including experience building scalable APIs and working with relational databases like PostgreSQL.
  • Experience owning features from planning to release, and a deep understanding of the full development lifecycle.
  • Solid understanding of PostgreSQL, basic SQL performance, and caching with Redis.
  • Proficiency with HTML/CSS and a strong grasp of responsive and accessible UI principles.
  • Familiarity with UI component libraries like NextUI, HeroUI, or similar.
  • Strong knowledge of Git, Docker, and version control best practices.
  • Exposure to CI/CD workflows and cloud infrastructure (AWS preferred).
  • Strong sense of responsibility and initiative — you take ownership of your work.
  • Clear, proactive communication and collaboration in a remote team.
  • Eagerness to learn, adapt, and grow alongside the team and product.
  • A pragmatic builder who can balance speed with maintainability.

Nice to have

  • Experience with D2C SaaS, LegalTech, or performance-marketing-driven products.
  • Familiarity with analytics, A/B testing, or data-driven product decisions.
  • Contributions to open-source projects or a strong personal portfolio.
