Job description

Overview

rePurpose is the Leading Packaging Sustainability and Compliance Platform for CPG brands to streamline EPR compliance and make credible sustainability claims.

At rePurpose, we believe a world free of plastic waste is achievable within our lifetime. To accelerate our impact, we are hiring a Senior Software Engineer with deep backend and infrastructure expertise to support our vision of solving the global waste crisis. As a Senior Software Engineer at rePurpose, you will play a central role in architecting and scaling our platform — building the reliable, high-performance systems that power compliance workflows, data pipelines, and sustainability insights for brands across the US and beyond.

This position is remote-only for East Coast candidates, but we prefer candidates based in New York to join our hybrid work environment.

Responsibilities

• Backend Development: Design, build, and maintain scalable server-side services and APIs, with a focus on performance, reliability, and security.

• Infrastructure & DevOps: Own and evolve our cloud infrastructure on AWS, including CI/CD pipelines, containerized deployments, monitoring, and cost optimization.

• Full-Cycle Development: Contribute across the full software development lifecycle — from architecture and planning through implementation, testing, and production deployment.

• Codebase Enhancement: Refactor and optimize the existing codebase to improve performance, reliability, and maintainability.

• Collaboration: Collaborate closely with cross-functional teams (product, design, and other engineering teams) to translate requirements into technical solutions.

• Technology Evaluation: Stay updated with industry trends, assess new technologies/frameworks, and propose their adoption where applicable to enhance the product’s capabilities.

Requirements

• Backend Expertise: Deep experience building robust, scalable, production-grade applications using Node.js or related backend frameworks. Strong grasp of API design (REST and/or GraphQL), service architecture, and performance optimization.

• Infrastructure & Cloud: Hands‑on experience with AWS (or comparable cloud platforms) and modern DevOps practices — including infrastructure‑as‑code (e.g., Terraform, CDK), containerization (Docker, Kubernetes), and CI/CD pipeline management.

• Database Knowledge: Proficiency in working with databases (SQL, NoSQL), designing schemas, optimizing queries, and ensuring data integrity.

• Security & Reliability: Familiarity with backend security best practices, observability tooling, and building fault‑tolerant, highly available systems.

• Full-Stack Awareness: Working knowledge of front‑end technologies (HTML, CSS, JavaScript/TypeScript) and modern frameworks (React, Vue, etc.) to collaborate effectively across the stack.

• Agile & Collaboration: Comfortable working in an Agile environment, excellent communication skills, and the ability to collaborate effectively within a team.

Qualification

• A degree in Computer Science or 3+ years of professional experience in software development, ideally in a cloud‑based modern stack. Typescript, Node.js, GraphQL, Vue, and AWS are all preferred.

• Strong problem‑solving abilities and a proactive mindset towards learning new technologies.

• Prior experience working in a startup or fast‑paced environment is a plus.

• Must be authorized to work in the United States.

Location Preference

This role is open to candidates based in the United States, with a preference for those located in or near New York City. We offer a hybrid working model for local candidates, with remote flexibility for those elsewhere in the US.
