Senior Front End Engineer - Remote

Headquarters: 151 Yonge Street 11th Floor Toronto, Ontario M5C 2W7 URL: https://www.eventmobi.com/ *** EventMobi is an all-remote company and this is a fully remote position, open to all candidates with a focus in Pakistan, India, Brazil, Columbia, Argentina and Mexico.  You will need to be able to work in EST time zones. ***   WHY YOU SHOULD JOIN US? At EventMobi, you won’t just ship UI features. You’ll help shape the core front-end architecture behind a global event platform used by thousands of organizations that rely on it to perform, scale and evolve. Our web applications are not thin presentation layers. They are large, offline-capable, cross-device React/TypeScript systems with shared design foundations, complex state management, performance-sensitive rendering and long-term architectural considerations.  The decisions you make here compound. We believe great software is built by engineers who take ownership beyond the ticket. You’ll have the space to challenge assumptions, improve abstractions, influence technical direction, and think in systems - not just components. We also believe the strongest engineers of the future know how to work with AI.  We actively encourage AI-native development to reduce repetitive work, increase quality and ultimately drive higher throughput — so your time goes toward design thinking, architecture, and meaningful problem-solving. If you care about product thinking, craftsmanship and building software that lasts, you’ll find real leverage here. HEAR FROM OUR SENIOR ENGINEER & DEV LEAD ALI: “I joined the team as a Software Engineer five years ago, and what keeps me here is the rare balance between high-level technical challenge and a genuinely sustainable pace. In many senior roles, you expect to spend your days 'extinguishing fires,' but here, the focus is on architectural integrity and long-term stability. The engineering culture is built on mutual respect and deep technical expertise. We don't just ship features to hit arbitrary deadlines; we take the time to conduct thorough, meaningful PR reviews that serve as a mentorship tool for the whole team. Having been here for half a decade, I've seen our systems evolve, and I've always felt empowered to take ownership of the roadmap and advocate for the right technical decisions. What stands out most is the lack of ego. Even as a Senior, I'm constantly learning from my peers. The environment is collaborative which makes it easy to focus on what actually matters - writing clean, scalable code and solving complex problems. If you're a seasoned engineer looking for a place where your experience is valued, your growth is supported, and your work-life balance is actually protected, this is the place to be.” WHAT YOUR WORK WILL FOCUS ON: This isn’t a “pixel pusher” role. You’ll operate at the intersection of product thinking, architecture, and hands-on engineering.
