About Align

Align is building the operating system for global trade execution.

International trade is one of the most complex operational environments in the world. Large companies move goods across borders while navigating fragmented systems, constantly changing regulations, and high compliance risk.

Align provides a Trade Operating System that sits at the center of those operations — encoding regulatory requirements, orchestrating workflows, and ensuring that trade decisions are executed correctly across internal systems.

We're building the infrastructure layer that allows global companies to operate trade reliably, compliantly, and at scale.

We’re an early-stage team with a lot to build. We move fast and hold a high bar for quality.

About The Role

We’re looking for a Senior Backend Engineer who loves building systems and shipping meaningful software quickly.

This role is primarily backend-focused, but we’re looking for a true builder — someone comfortable owning problems end-to-end and willing to step into frontend work when needed, especially with the help of modern AI tools.

You’ll work on the core infrastructure powering Align’s Trade Operating System: workflow orchestration, data pipelines, compliance logic, and integrations across complex enterprise systems.

This is a high-ownership role where you’ll help shape both the architecture and the product as we scale.

What You'll Do

• Design and build backend services that power Align’s trade execution platform

• Implement systems for workflow orchestration, compliance rules, and operational decisioning

• Work with complex datasets and build pipelines that process trade-related data

• Integrate external systems and APIs used in enterprise trade operations

• Collaborate closely with product and design to ship new features quickly

• Own features end-to-end when needed, including occasional frontend implementation

• Use modern AI tools to accelerate development and experimentation

• Contribute to system architecture and long-term technical direction

What We're Looking For

At the core, we value two things:

Ship a lot. Ship it well.

Beyond that, we’re looking for someone who:

• Has strong opinions about software design and can clearly defend them

• Moves with urgency without sacrificing quality

• Is comfortable working with ambiguity and figuring things out independently

• Takes ownership of problems and drives them to completion

• Uses AI tools as a force multiplier, not a crutch

• Enjoys building real systems that solve operational complexity
