Software Engineer (Full Stack Developer)

As part of our expanding global engineering team, you will play a key role in developing and supporting applications used across multiple sites worldwide. You will work closely with a California-based team, including a night-shift group aligned with your time zone, enabling seamless collaboration and continuous progress.

We are looking for an engineer who values teamwork and has experience contributing to shared codebases, participating in code reviews, and collaborating on complex applications.

You will contribute across the full stack, working with modern frontend technologies such as React and Tailwind CSS, alongside backend systems built with Node.js, Python, and RESTful APIs. If you enjoy building high-quality software while supporting a globally distributed team, this is a great opportunity to make a meaningful impact.

• Collaborate with engineers, product managers, and stakeholders across global teams to design, develop, and maintain web applications

• Contribute to shared codebases using best practices for version control, code reviews, and team-based development

• Build and enhance frontend experiences using modern technologies such as React, TypeScript, and UI frameworks (e.g., Tailwind CSS, shadcn)

• Develop and maintain backend services and APIs using Node.js, Python, and frameworks like Express.js

• Design, query, and optimize both SQL and NoSQL databases (e.g., MySQL, SQLite, MongoDB)

• Participate in regular communication with California-based teams, including overlap with night-shift operations, to ensure alignment and continuity

• Troubleshoot and resolve issues across the stack, supporting applications used by sites around the globe

• Contribute to system improvements, scalability, and performance optimization efforts

• Actively participate in team discussions, planning sessions, and continuous improvement initiatives

• Support the growth of the engineering team by sharing knowledge, mentoring, and promoting strong collaborative practices

• Bachelor’s degree in Computer Science or a related field, or completion of a reputable web development bootcamp, or equivalent practical experience

• Experience working in a collaborative software development environment, contributing to shared codebases as part of a team

• Strong communication skills, with the ability to effectively collaborate with developers, product managers, and stakeholders across distributed teams

• Ability to work with globally distributed teams, including participation in occasional off‑hours meetings to maintain alignment across time zones

• Strong problem‑solving skills, with the ability to debug, troubleshoot, and contribute to complex applications

• Self‑motivated, proactive, and comfortable working in a fast‑paced, team‑oriented environment
