Job description

At AppWork, we’ve built a simple, user-friendly PropTech platform that modernizes maintenance operations. Our platform brings everything into one easy-to-use platform so property managers, maintenance teams, and residents can all enjoy a smoother, more connected experience.

As a member of the AppWork team, you’ll be helping to build and deliver technology that solves real problems, makes communities run better, and creates happier teams and residents.

About The Role

We’re looking for an experienced, hands‑on Senior Full Stack Engineer to join our growing R&D team.

This is a unique opportunity to influence AppWork’s product experience end‑to‑end - from building intuitive, high‑performing user interfaces to designing scalable backend systems. You’ll play a central role in shaping our product architecture, collaborating closely with design and product teams to bring seamless, beautiful, and impactful user experiences to life.

What You’ll Do

• Design, build, and maintain end-to-end features across the stack - from modern front-end interfaces to robust backend services.
• Elevate User Experience: Work closely with our design team to translate mockups and design concepts into high-quality, pixel-perfect, and responsive user interfaces.
• Architect & Optimize: Contribute to architectural decisions that ensure system scalability, reliability, and performance, leveraging best practices in modern web development.
• Collaborate Cross-Functionally: Partner with Product, Design, and other engineering teams to align technical execution with product goals and deliver exceptional user value.
• Mentor & Inspire: Share best practices, guide junior engineers, and help foster a culture of craftsmanship, collaboration, and technical excellence.

Qualifications

• 2+ years of Elixir experience required.
• A passionate builder who thrives on both frontend and backend development, with a keen eye for design and user experience.
• 7+ years of experience in full stack development, with a strong track record of delivering production‑grade web applications.
• Deep hands‑on expertise with modern frontend frameworks such as React, Angular, or Vue.js.
• Proficiency in building and integrating RESTful APIs and working with SQL/NoSQL databases.
• Experience collaborating directly with design teams and familiarity with design systems, UX best practices, and component-driven development. Solid understanding of AWS cloud services and scalable system architecture.
• Familiarity with message queues (Kafka, SQS, RabbitMQ, Oban) and asynchronous processing.
• Excellent communication and collaboration skills — able to bridge the gap between design, product, and engineering.
• Strong sense of ownership, product mindset, and passion for delivering exceptional experiences that excites users.
• This role is contingent upon successful completion of a background check.
