Their platform handles complex integrations, large-scale workflows, and data orchestration—all with a mission to empower teams through intelligent automation.

About the Role

Our client is seeking a Senior Software Engineer (Backend) to join their Internal Tools and Infrastructure Engineering group. This fully remote role centers on building backend services, systems integrations, and workflow orchestration tools that power internal operations—ranging from order management and tax services to search and payments. You’ll work across a rich ecosystem of APIs and services, developing highly reliable tools and pipelines with minimal UI work.

This role is perfect for an autonomous backend engineer who thrives in integration-heavy environments, loves clean architecture, and is comfortable driving projects from spec to ship—fast and with strong judgment.

Responsibilities

Build Backend Systems : Design and maintain internal services and data pipelines using Go (Golang), orchestrating workflows via Airflow and supporting business-critical functions.

Drive System Integrations : Own backend integrations across key third-party platforms including Salesforce OMS, CommerceTools, Stripe, Avalara, Algolia, Constructor, and more.

Orchestrate Internal Workflows : Develop event-driven infrastructure and services that power operational systems like the internal lead engine and fulfillment tooling.

Collaborate Cross-Functionally : Partner with product, frontend, and DevOps teams to ensure backend services align with business goals and scale efficiently.

Promote Reliability & Speed : Contribute to service observability, automated deployments, and continuous integration practices in an AWS-based environment.

Contribute to System Design : Bring opinionated thinking to architectural decisions, document your work clearly, and mentor others when needed.

Requirements

Backend Expertise : 5+ years of experience as a backend software engineer, with a strong command of Python / Go (Golang) for building distributed systems.

Workflow Orchestration : Hands-on experience with tools like Airflow to manage complex data and task pipelines.

API Fluency : Ability to independently integrate and work with third-party APIs, including reading documentation, scoping solutions, and implementing with minimal oversight.

Event-Driven Architecture : Familiarity with Kafka or similar messaging / event streaming systems.

Cloud Experience : Proficient in AWS-based infrastructure , with working knowledge of ECS, Kubernetes, and Docker.

DevOps Literacy : Comfortable with GitHub-based workflows, CI / CD tools, and Infrastructure-as-Code practices in a GitOps environment.

Nice-to-Haves : Exposure to data platforms such as Snowflake is a plus, as is experience working alongside frontend teams (React / Next.js) to provide clean, efficient APIs.

Benefits & Why Join

Impactful Engineering Work : Contribute to critical internal platforms that streamline the company’s ability to scale and operate efficiently.

Remote Flexibility : Work from anywhere while collaborating with high-performing distributed teams.

Modern Tech Stack : Leverage a cutting-edge toolset—Go, Kafka, Airflow, AWS, Docker—and build scalable systems with real business impact.

Strong Engineering Culture : Join a company where speed, autonomy, and thoughtful architecture are deeply valued.

Career Growth : Set foundational patterns for a team that’s growing rapidly; future leadership opportunities as the team scales.

Comprehensive Benefits : Competitive compensation, health benefits, paid time off, and wellness support.

If you’re a backend-focused engineer who loves systems thinking, thrives on shipping fast and clean backend code, and knows how to turn complex workflows into elegant services—this is your chance to make a real impact.
