He worked as an iOS engineer at Wayfair from 2019 to 2020, attaining the title of iOS Engineer II.

Chan then joined HEIR as a founding software engineer from 2021 to 2022, taking an early-stage role in building the platform's technical foundations. From 2022 to 2024, he co-founded timelyAI, a workforce technology venture, before serving as a senior software engineer at Vault.fm from 2024 to 2025.

Chan co-founded Sira in 2025. The company is designed as an AI-native workforce management platform targeted at industries that rely heavily on deskless and field-based employees, offering an integrated suite of tools that includes automated time tracking, payroll processing, employee scheduling, and human resources functions. The platform uses artificial intelligence to automate routine administrative tasks, such as detecting missed clock-ins and flagging scheduling anomalies, with the goal of reducing manual overhead for managers overseeing distributed workforces. Sira's clients include companies in sectors such as private security, cleaning services, landscaping, and home health care.

In 2025, Sira announced a $3.4 million seed funding round.Template:Better source needed
