Team: IT
This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Ingénieur·e logiciel principal (Staff Software Engineer) – Commerce HTS based in Canada.
This role sits at the intersection of large-scale platform engineering, product innovation, and AI-accelerated software delivery. You will contribute to a high-impact commerce technology platform that powers partner-facing travel and fintech experiences used by millions of end users globally. The environment is fast-moving, low-process, and deeply collaborative, with a strong emphasis on ownership and technical autonomy. You will work alongside senior engineers, product managers, and business stakeholders to shape scalable systems and end-to-end features. A key part of the mission is building intelligent, multi-tenant commerce capabilities that enable partners to launch and grow rapidly. This is also a highly forward-looking engineering context where AI-assisted development, automation, and agent-based workflows are actively embraced to accelerate delivery and quality.
Accountabilities:
In this role, you will take ownership of designing and delivering scalable, high-impact systems that support a multi-tenant commerce platform and its partner ecosystem. You will work across the stack (primarily backend) to ensure seamless end-to-end delivery of features and platform capabilities.
- Lead the design and implementation of scalable backend systems and foundational architecture patterns that support partner commerce experiences at scale
- Own features end-to-end, ensuring successful delivery from backend services through to partner-facing product capabilities
- Build and optimize systems that support AI-assisted development workflows, including feedback loops, guardrails, and agent orchestration
- Collaborate with product managers and business stakeholders to define, refine, and execute roadmap priorities
- Drive technical decisions through clear documentation, asynchronous alignment, and strong engineering judgment
- Improve codebases and engineering practices to enable faster, safer development for both engineers and AI-driven workflows
- Contribute to a culture of high-quality engineering through peer collaboration, feedback exchange, and continuous improvement
- 8+ years of software engineering experience, including work on distributed systems and large-scale backend platforms
- Strong experience in backend development (Scala preferred, with openness to Go, Java, Python, or similar languages)
- Experience working with cloud environments (e.g., GCP or equivalent) and building scalable service-oriented architectures
- Proven ability to design and operate complex systems with attention to performance, reliability, and scalability
- Strong product mindset with the ability to align technical decisions to customer and business outcomes
- Hands-on experience (or strong interest) in using AI tools, LLMs, or agent-based systems to accelerate software development
- Ability to design workflows, guardrails, and feedback mechanisms for AI-assisted engineering
- Excellent communication skills, with the ability to articulate technical trade-offs and influence stakeholders
- Comfort working in autonomous, low-process environments with high ownership expectations
- Strong analytical thinking and ability to quickly ramp up in unfamiliar codebases and domains
- Competitive compensation with pre-IPO equity opportunities
- Comprehensive health coverage including medical, dental, and vision support
- Life, short-term, and long-term disability insurance
- Health spending account for eligible expenses
- Retirement savings plan with employer contributions
- Paid time off, including generous vacation policies
- Remote-friendly work environment with home office support and coworking flexibility
- Parental leave policies above industry standards
- Travel and lifestyle allowances and perks depending on eligibility
- Access to telemedicine and employee wellness programs
- Strong culture of autonomy, innovation, and high-impact engineering work.
