Senior Backend Software Engineer, Integrations Platform [Canada]

At Vanta, our mission is to help businesses earn and prove trust. We believe that security should be monitored and verified continuously, and we empower companies to practice better security and prove it with ease. Vanta has a kind and talented team, and while some have prior security experience, many have been successful at Vanta without it. Our Senior Software Engineers lead and mentor engineers, delivering high-value products for our customers and infrastructure that enables our business to scale. Vanta’s team and technology surface are growing quickly, and it’s essential that we invest in the right abstractions and systems to enable us to scale with our business. As a Senior Software Engineer, you’ll be responsible for setting technical direction to enable our product and infrastructure to scale with our business, driving complex projects across our technical stack, and mentoring our talented engineering team. Your past experience will be leveraged to enable and accelerate Vanta’s growth. Our business has found incredible product-market fit and has monetized effectively since the day we signed our first customer. We’re growing at a blistering pace, which presents career-defining opportunities for engineers to accelerate their growth and to contribute to a rapidly-scaling company.

The Integrations Platform team mission is to power the world’s largest trust automation ecosystem, enabling any person or agent to build, connect, and automate trust seamlessly. We own Vanta’s integration ecosystem, which currently includes over 400 integrations across Cloud Providers (AWS, Azure, GCP), Identity Providers, Mobile Device Management (MDM), and Human Resources Information System (HRIS). We are focused on developing the Integration Platform. This includes creating shared primitives for authentication, lifecycle, observability, and publishing to ensure all integrations are built on the same foundation. Our North Star is to eliminate the barrier to building integrations entirely. We aim to enable anyone to create an integration in minutes using declarative, low-code, and no-code patterns, supercharged by AI Agents. What you’ll do as a Senior Software Engineer at Vanta: - Set technical strategy and direction for critical platform surface areas, staying ahead of rapid growth. - Design and evolve the APIs, primitives, and self-service golden paths that internal teams, partners, and customers build on. - Own the authentication, data-ingestion, and schema-evolution primitives that keep integrations with external systems secure and reliable at scale. - Build secure, well-documented, scalable backend services and developer tooling (including CI/CD) that propel engineering productivity. - Drive performance, operational excellence, and SDLC best practices; make and defend buy-vs-build and one-way-door decisions. - Act as a force multiplier: mentor and uplevel teammates, and set the design patterns the team standardizes on. - Build with TypeScript, React, and Node.js, and use AI tools to accelerate development and workflows. How to be successful in this role: - 8+ years of backend development building reliable, scalable, fault-tolerant systems. - Platform and API design: you've evolved core APIs, SDKs, and platform abstractions, with deep expertise in RESTful APIs, GraphQL, authentication protocols (OAuth, API keys, JWT), and security best practices. - Data Integrations: you've built resilient data ingestion from external systems, including integrations with cloud providers, HRIS platforms, identity providers, and code repositories. You champion best practices such as rate limiting, retries and idempotency, webhooks, and handling schema drift. - Systems thinking at scale: you design for scale, reliability and failure modes. You look around corners and proactively identify and address risk. - Technical leadership and c
