Job description

 At Breakthrough, we empower our clients with data, technology, and market knowledge to reduce costs, create efficient networks, and decarbonize transportation. As a strategic partner to our clients, we challenge legacy practices in the $700 billion transportation industry, delivering sustainable fuel and freight products that foster fair partnerships and environmental responsibility.
As a digital product company, our culture thrives on curiosity, autonomy, and purpose-driven innovation. Here, you're not just executing tasks; you're collaborating with a team dedicated to transforming transportation and making a tangible impact on the global economy and the planet.
The Role
As a Senior Software Engineer, you'll play a pivotal role in developing and enhancing digital products that enable shippers to optimize the way freight moves around the globe. Your expertise will guide the design and implementation of scalable systems, contributing across the stack-from APIs and infrastructure to user interfaces. This role is full stack (UI & API's) with more front end focus.
We're seeking individuals who excel in collaborative environments, are driven by the "why" behind their work and the core problems they're trying to solve, and are eager to develop innovative solutions while influencing the evolution of our systems, teams, and culture.
"At Breakthrough, we're figuring out things for the first time; things that no
one else has ever done before" - Engineering leader, Breakthrough
JOB RESPONSIBILITIES
What You'll Do
  • Collaborate with cross-functional teams-including product owners, designers, and fellow engineers-to build reliable, scalable systems.
  • Working closely with our clients, market experts, and the broader Breakthrough team, you will build innovative solutions that solve industry problems.
  • Lead the end-to-end design and implementation of new product features and services.
  • Learn and apply the latest technologies to our cloud native solutions.
  • Write clean, maintainable code accompanied by comprehensive automated tests.
  • Review pull requests, mentor other engineers, and elevate the technical standards within the team.
  • Contribute to technical strategy, system design, and process improvements.
  • Participate in our on-call rotation and support production systems, embracing a shared ownership model.

Learn more about the work you'll do at Breakthrough and our culture here.
This Role Might Be a Great Fit If...
  • You're enthusiastic about tackling complex challenges and can distill them into actionable solutions.

  • You prioritize writing clean, readable, and testable code, while understanding the importance of pragmatism.

  • Understanding the underlying purpose of your work motivates you, beyond merely delivering features.

  • You thrive in collaborative settings, engaging with engineers, product owners, and designers to achieve common goals.

  • You're committed to advancing sustainability in transportation and reducing environmental impact through technological innovation.

This Role Might Not Be the Best Fit If...
  • You prefer working in isolation or solely on predefined tasks without broader context.

  • Adaptability to shifting priorities in a dynamic environment is challenging for you.

  • Collaborating with non-engineering disciplines, such as product and design, doesn't align with your working style.

  • You seek a rigid hierarchical structure to guide all decision-making processes.

  • Mentoring others and contributing to team growth aren't areas of interest for you.

How We Work
  • Hybrid-Friendly: While many team members are based in Green Bay, we embrace remote work and prioritize impact over location.

  • Cross-Functional Teams: You'll be part of an agile team comprised of product owners, designers, QA specialists, and fellow engineers, fostering a holistic approach to product development.

  • Continuous Improvement: We regularly conduct retrospectives, refine our processes, and invest in addressing technical debt to enhance our workflows.

  • Empowered Engineers: Beyond task execution, you're encouraged to influence both what we build and how we build it, ensuring alignment with our strategic objectives.

QUALIFICATIONS
What you bring
  • You have 5+ years of experience in software engineering, preferably within product-oriented teams (external/client facing solutions). Experience with front-end development required.

  • Proficient in building and deploying applications using modern tools and frameworks

  • You have a Bachelor's degree in Computer Science or related technical field involving coding (e.g., physics or mathematics), or equivalent technical experience

  • Adept at navigating ambiguity, simplifying complex problems, and balancing short-term needs with long-term objectives.

  • Collaborative by nature, you value pairing, whiteboarding sessions, and learning from diverse perspectives.

  • Passionate about delivering high-quality products that enhance client experiences and drive sustainability in transportation.

Tech We Use
  • Backend: Python, Postgres

  • Frontend: Node, React, TypeScript, graphQL

  • Cloud & Infrastructure: Google Cloud Platform (GCP), Terraform, Docker

  • Data & Analytics: BigQuery, dbt

  • Monitoring & Observability: GCP Monitoring

While expertise in every technology isn't required, familiarity with our stack is beneficial. We're keen to work with individuals who bring relevant experience and a willingness to learn.
Why Breakthrough
  • Mission-Driven Work: Engage in projects that have a tangible impact on the economy and the environment. Hear more about our innovation in this video.

  • Supportive Culture: Experience a workplace that values autonomy, growth, and meaningful contributions.

  • Leadership Opportunities: Take on roles that allow you to mentor, guide, and shape the future of our products and technological direction.

  • Established Backing: As a U.S. Venture company, we benefit from a legacy of innovation and a commitment to sustainable practices.
