Quartermaster Inc.
BUILD SOMETHING YOUR NEIGHBOURS WILL LOVE
We’re building Toronto’s dedicated platform for home management to empower the city’s homeowners and to better connect our neighbours and the local Pros they trust.
Our focus is purely on the GTA market right now. We build our property base one street at a time, and our marketplaces one neighbourhood at a time. We’re a local tech company in every sense of the word. We start with integrity, neighbourhood values, and competitive craftsmanship, and we build our business on neighbourhood trust.
We believe in holistic solutions to consumer problems. We believe in high-trust hyperlocal communities. We believe in low commission marketplaces that the best Pros can actually say yes to. And we believe that tech companies should go to work for the locally loved Pros of the GTA rather than trying to get those Pros to effectively work for the tech company. We believe that it’s good business to care. We believe that this problem space deserves a form of digital transformation that the people and Pros of Toronto can trust and invest in.
If this resonates with you and you’re at a point in your career and your life where you want to do something uniquely difficult for a meaningful outcome, you’ve found your next home.

ROLE OVERVIEW
The Senior Front-End Developer is a key individual contributor responsible for building high-quality, performant, and accessible user interfaces across both web and native mobile platforms. This role involves owning complex UI implementations, contributing to front-end architecture decisions, and driving the adoption of scalable design patterns and reusable components. The engineer works closely with the design team to implement and evolve design systems that reflect the brand’s identity and accessibility standards. They are expected to contribute hands-on to critical projects while mentoring junior engineers and helping elevate the technical quality of the team. Strong collaboration with product managers, designers, and cross-functional peers is essential, as is a consistent focus on delivering elegant and intuitive user experiences. The ideal candidate combines deep technical expertise with a sharp eye for detail and a commitment to user-centered design, continuously improving both the codebase and the end-user experience.

Decision-Making & Collaboration
- Guide front-end architectural decisions across web and mobile, balancing business needs, platform constraints, and developer efficiency
- Collaborate with product managers and the design team to define technical specifications, prioritizing accessibility and platform parity
- Partner with the design team to ensure consistent behavior and appearance of shared components across environments
- Make tradeoffs transparent to stakeholders and own the implications of mobile vs web technical decisions
Leadership & Mentorship
- Mentor junior and mid-level engineers in front-end and mobile development, accessibility, and system design principles
- Lead code reviews, architecture sessions, and cross-platform design discussions with a focus on performance and accessibility
- Support team learning through documentation, knowledge-sharing, and feedback-driven growth
- Advocate for accessibility and mobile quality in engineering culture and product planning
Agile Process & Delivery
- Own backlog health, sprint planning, and delivery of features across mobile and web surfaces
- Ensure accessibility and mobile-specific concerns are integrated into tickets, planning, and QA processes
- Drive cross-team coordination and unblock dependencies across platform-specialized squads
- Continuously evolve team practices to support fast, reliable, and inclusive front-end delivery
WHAT YOU BRING
Candidates should have 6+ years of professional front-end development experience, with at least 2 years leading technical projects or teams. They must have deep expertise in modern JavaScript or TypeScript frameworks, preferably React, and experience delivering native mobile applications using technologies such as React Native, SwiftUI, or similar. A strong track record of implementing and scaling design systems, including design tokens, component libraries, and accessibility standards, is essential. Candidates should be comfortable owning architectural decisions, mentoring junior engineers, and collaborating closely with product managers and the design team. Familiarity with WCAG compliance, semantic markup, and accessible patterns across platforms is expected. The ideal candidate is curious, feedback-driven, and committed to building inclusive, high-quality user experiences across both web and mobile. They consistently advocate for user needs, ensuring that performance, accessibility, and design intent are reflected in every feature shipped.
THIS IS A GOOD FIT FOR YOU IF…
- You’re mission-driven and looking to solve the mission’s hardest problems.
- You’re at a point in your life and your career where you want to tackle a uniquely demanding job to produce meaningful impact.

TEAM VALUES
Integrity – We prioritize integrity over comfort, convenience, and the short-cuts of success that drive metrics but undermine trust.
Trust – We cannot win unless we win on trust. Trust is hard to earn and easy to lose. We need to be built for it in our DNA.
Competitiveness – We believe that competitiveness is a critical complement to integrity and trust. If we’re not our customer’s best choice, then we’re wasting their time. We believe in the power of healthy competitive markets, and we believe we need to be uniquely competitive to win in this space. We have too much respect for the other players in this space to expect things to be easy. That’s a good thing.
Empowerment – Any win we achieve needs to be first and foremost a win that we deliver to others, starting with our customers, and their long term best interests.
VACATION AND BENEFITS
We know the power it takes to be successful in a challenging mission and we want to ensure our team is rested and ready to go.
- We offer 30 days of PTO annually, which can be used for vacation, personal days, or illness. Five of these days are designated as company-wide closures around the start and end of the year.
- In addition, our benefits plan covers health, dental and wellness to add that extra pep in our step, and help us sleep at night.
- We have a tech allowance benefit to help set you up for work.
- We have pregnancy and parental leave policies, and we’re ready to support your family’s next stage of growth.
EMPLOYEE OWNERSHIP
We’re a team on a mission. We expect a high degree of ownership from each other and we pair that with higher than usual employee ownership in the company.
