Software Engineer, Python, Backend Developer

Via Separations is a Boston-area startup dedicated to enabling process efficiency and intensification for the industrial sector. In 2024, Via delivered its first commercial facility and changed the narrative around market-driven energy technologies that drive value for industrial customers. At the intersection of engineering, society, and impact, our team is passionate about making a difference and building the technology and organization to do it.

We are a fast-paced, interdisciplinary team backed by leading venture capital firms, and we are looking to add talented, mission-driven people to our cohort.

We are passionate about transformative impact,
optimistic about scientific progress, and unafraid of hard problems. We believe that our people are our unfair advantage, and drive our mission forward. We embrace the diversity of our team for creative solutions and believe the best ideas come from the intersection of disciplines and perspectives. We want you to join us!

We are seeking a Software Engineer to own and evolve our cloud infrastructure and back-end systems while contributing to the ongoing development and improvement of our codebase. This role complements our existing developer’s expertise in database architecture and web application development — bringing deep AWS cloud knowledge and back-end systems thinking to our small, high-impact engineering team.

As part of our team, you will take ownership of our AWS infrastructure across multiple environments, debug and enhance existing Python and Type Script codebases, and help establish the engineering processes and best practices that will allow Via to scale. Your intellectual curiosity and willingness to roll up your sleeves and dig into a potentially unfamiliar problem will help our company grow its software platform and internal tooling while maintaining high standards of quality and reliability.
