Role summary
OpenTable is seeking a Backend Software Engineer II for its TMS Inventory team. This hybrid role involves working in the Toronto office two days a week. The team manages the core availability and reservation engine, focusing on real-time systems, reservation flows, and the availability publishing pipeline. Responsibilities include designing and implementing backend features, working across the full development lifecycle, debugging production issues, and improving system reliability. The role requires proficiency in C#/.NET, Kubernetes, Kafka, Redis, MongoDB, CI/CD, and observability tools. The engineer will contribute to a mission-critical distributed backend platform.
This will be a remote role to start, with plans to transition to hybrid in-office 2x/week located in downtown Toronto.
With millions of diners, 70,000+ restaurant partners and 25+ years of experience, OpenTable, part of Booking Holdings, Inc. (NASDAQ: BKNG), is an industry leader with a passion for helping restaurants thrive. Our world-class technology empowers restaurants to focus on what matters most – their team, their guests, and their bottom line – while enabling diners to discover and book the perfect restaurant for every occasion.
Every employee at OpenTable has a tangible impact on what we do and how we do it. You’ll also be part of a global team and its portfolio of metasearch brands. Hospitality is all about taking care of others, and it defines our culture.
The OpenTable for Restaurants (OT4R) platform is the heart of OpenTable and connects restaurants to our network of over 25 million diners. The OT4R iOS app is a sophisticated software tool that enables restaurant hosts, servers, managers, and owners to plan shifts, manage tables, and grow their business.
As a part of the team, you’ll collaborate with a hardworking and diverse group of engineers, designers, and product managers who are committed to building beautiful, scalable, high-value features. On this team, you will explore a variety of deeply complex and rewarding domain areas, offering plenty of opportunities for professional growth (plus lots of opportunities to just geek out). From inventory management and high-performance data synchronization to crafting sophisticated yet intuitive user interfaces, OT4R has something for everyone.

Benefits and Perks
The best connections happen face-to-face, whether you’re sitting down to dinner or having coffee with a coworker. That’s why OpenTable has adopted a hybrid workplace model. This role aligns with that approach, with an expectation of coming into the office two days a week—giving employees the best of both worlds: in-person collaboration and flexibility.
There are a variety of factors that go into determining a compensation range, including but not limited to external market benchmark data, geographic location, and years of experience sought/required.
We offer a competitive base salary and benefits including: health benefits; flexible spending account; retirement benefits; life insurance; paid time off (including PTO, paid sick leave, medical leave, bereavement leave, floating holidays and paid holidays); and parental leave benefits. This role is eligible to be considered for an annual bonus and equity grant.
Work Environment & Flexibility
At OpenTable, we pride ourselves on fostering a global and dynamic work environment. As a team member with us, you will benefit from a schedule tailored to accommodate a global workforce operating across multiple time zones. While the majority of your responsibilities may align with conventional business hours, there will be instances where you are expected to manage communications - via calls, Slack messages, or emails - outside of regular working hours to effectively collaborate with international colleagues, respond to restaurant partners, and/or address urgent matters. OpenTable will always abide by and consider local laws and regulations.
Inclusion
We’re committed to creating a workplace where everyone feels they belong and can thrive. We know the best ideas come when we bring different voices to the table, so we're building a team as dynamic as the diners and restaurants we serve—and fostering a culture where everyone feels welcome to be themselves.
If you need accommodations during the application or interview process, or on the job, we’re here to support you. Please reach out to your recruiter to request any accommodations.
