Operating at a massive scale across multiple regions, we’re redefining how businesses connect with people beyond the inbox. If you’re driven to build category-defining technology and want to shape the future of offline communications, join our high-calibre team and help us transform the way the world sends mail.

About The Team:

We believe in collaborative code reviews, a culture of continuous learning, and owning our projects from conception to deployment.

What you’ll do:

As a Senior Software Engineer on the Integrations team, you will be a key contributor to our integrations, responsible for both technical leadership and hands-on development. You'll build the critical backend and frontend systems that allow our customers to use our product without leaving their stack.

Platform Integrations: Develop and maintain the integration layer between PostGrid's core platform and third-party ecosystems. This includes designing scalable data pipelines for CRM and ERP platforms, debugging and resolving integration failures at the API and data layer, and engineering internal tooling to automate partner onboarding and system monitoring.
Partner & Integration Advocacy: Own the technical relationship with key integration partners. This includes reviewing integration architecture, identifying failure points and reliability risks, and driving engineering solutions internally to expand integration coverage, improve uptime, and ensure long-term stability across all connected platforms.

What Will You Bring To This Role:

Minimum Requirements:

5+ years of software engineering experience as full stack with a strong focus on integrations, APIs, or platform engineering.
Strong proficiency in TypeScript, NodeJS, MongoDB
Experience with scalable architecture, high load applications
Hands-on experience building integrations with CRM/ERP platforms and other 3rd-party systems and internal platforms
Solid understanding of REST APIs, webhook patterns and event-driven systems

Experience with programming languages like Rust to solve performance-intensive engineering challenges and tasks

What we offer:

Deep architectural control with a role in shaping the company’s critical platform integrations.

Professional development opportunities, including mentorship from senior leaders and access to advanced training programs.

A collaborative environment focused on achieving excellence and driving innovation.

Our Commitment to Diversity:

PostGrid is an equal opportunity employer and values the diversity of backgrounds and perspectives. We strive to cultivate an inclusive environment of understanding to have a greater impact on our business and our customers.
