We are looking for a Staff Full‑Stack Engineer to lead the design and development of mission‑critical product features and services that power our platform, used daily by thousands of travelers worldwide. You will play a pivotal role in shaping technical direction, mentoring engineers, and driving cross‑team initiatives to deliver scalable, reliable, and user‑focused solutions.

What You’ll Do

  • Lead technical strategy and architecture for core backend and frontend components of the platform, ensuring scalability, reliability, and performance.
  • Own complex domains end‑to‑end: from design through development, launch, and ongoing evolution of key microservices and customer‑facing features.
  • Influence cross‑functional teams (engineering, product, design) by aligning technical execution with business goals and long‑term product vision.
  • Raise the technical bar through code reviews, architectural guidance, and fostering best practices in testing, monitoring, and documentation.
  • Mentor and coach engineers across the organization, helping to grow technical skills and leadership capabilities.
  • Partner with leadership to define and execute a multi‑year technical roadmap, ensuring that platform investments support company growth at scale.

What We’re Looking For

  • 5+ years of software development experience, with deep expertise in both backend and frontend systems.
  • Strong programming skills and CS fundamentals, with mastery in at least one backend language (Java, Python, etc.) and modern frontend frameworks (React, Angular, TypeScript).
  • Proven experience designing and evolving large‑scale distributed systems and microservice architectures.
  • Demonstrated ability to own technical domains, making architectural trade‑offs and long‑term design decisions.
  • Experience driving cross‑domain initiatives, coordinating with multiple teams to deliver cohesive solutions.
  • Track record of mentoring engineers, leading technical discussions, and influencing outcomes at an organizational level.
  • Experience with cloud platforms (AWS preferred), CI/CD pipelines, and modern DevOps practices.
  • Passion for solving complex problems, continuously learning, and delivering customer‑focused innovations.
  • Excellent communication skills with the ability to influence technical and non‑technical stakeholders alike.
