Senior Full-Stack Software Engineer, Integrations

Title: Senior Full-Stack Software Engineer, Integrations Location: Canada - Remote

We’re searching for a Senior Full-Stack Software Engineer to help build our new Integrations pod. Our Portal connects with the HR, payroll, driver safety, and expense management systems our customers already use. These integrations keep driver information current and support some of our most important customer workflows.

When an integration fails, the impact can be difficult to spot: a new hire never appears, a former employee stays active, or information falls out of sync. You’ll build connections customers can trust and make sure we catch problems before they do.

Reporting to the Manager of the team, you’ll own integrations end to end, from a partner’s API to the screens customers use to connect and configure them. As one of the pod’s first engineers, you’ll help establish its technical standards, delivery practices, and approach to keeping integrations healthy in production.

What You’ll Do

• Own integrations from design through launch and ongoing production health, partnering with Product, QA, and the other Portal engineering teams.
• Work with Product and partners to clarify requirements, resolve gaps in API documentation, agree on scope, and deliver against committed dates.
• Build backend services, data models, APIs, background jobs, and customer-facing interfaces for connecting and configuring integrations.
• Design data mapping, synchronization, retries, and reconciliation within established platform patterns, documenting key decisions in architecture decision records.
• Build syncs, webhooks, and scheduled jobs that handle rate limits, duplicate events, partial failures, and partner outages without creating unnecessary manual cleanup.
• Create shared building blocks and clear adapter interfaces for authentication, data mapping, synchronization, and error handling, making each new integration easier to deliver.
• Build monitoring, alerts, and runbooks that help the team detect failures early and recover reliably.
• Help customers connect, configure, and check the health of their integrations independently.
• Protect partner credentials and personal information through secure token handling, encryption, least-privilege access, safe logging, and reliable separation of customer data.
• Use AI coding agents to accelerate development and testing while carefully reviewing their output. Help shape how the pod uses AI for integration work.
• Strengthen the pod’s standards for design reviews, code reviews, testing, documentation, and production support.
• Hold launches that don’t meet agreed standards for data correctness, security, and monitoring, working with the Lead Mobile Engineer and Product on go/no-go decisions.

In your first 30 days, you’ll learn how our existing integrations work and ship changes to at least one in production. Within three months, you’ll have designed, scoped, and delivered your first new integration by its agreed deadline. Within six months, several integrations you’ve contributed to will be live and meeting their quality goals, and you’ll be a go-to expert for the other Portal teams.

What You Bring

• 7+ years building production software, including at least 3 years building and running third-party integrations. Your track record matters more than your title.
• Strong full-stack experience across backend services and product interfaces, with ownership spanning data models, APIs, background jobs, and customer-facing screens.
• Experience designing, shipping, and operating integrations that customers depend on, including syncs, webhooks, and scheduled jobs.
• A practical understanding of retries, duplicates, partial failures, rate limits, and partner outages. You can explain an integration failure you handled and what you changed afterward.
• Experience designing reusable integration architecture, including adapter interfaces and shared capabilities for authentication, mapping, synchronization, and error handling. You know when an abstraction helps.
• A track record of delivering large features or products against firm deadlines by breaking down work, sequencing delivery, raising risks early, and making deliberate scope decisions.
• The ability to turn a goal and incomplete information into clear requirements, working directly with Product and partners to close gaps and move delivery forward.
• Experience using AI coding agents such as Cursor or Claude Code to deliver faster, with sound judgment about context, verification, and the mistakes AI-assisted development can introduce.
• Production experience protecting credentials and personal information, including OAuth, token handling, encryption at rest, least-privilege access, safe logging, and separation of customer data.
• The ability to improve the work of other engineers through thoughtful design and code reviews.

Our current stack includes TypeScript, NestJS, Next.js, React, PostgreSQL with Prisma, BullMQ, Redis, Vitest, Playwright, GitHub Actions, Datadog, and Flagsmith feature flags.
