Join our team as a Senior Software Engineer!

This is a fixed hybrid role on-site Tuesday, Wednesday, Thursday at HQ in Maple Plain, MN.

The Pricing Team at Protolabs is responsible for building and maintaining the intelligence that powers how we quote custom-manufactured parts. We operate at the intersection of a complex two-sided marketplace: when a customer uploads a CAD file, they receive an instant quote, even before we know which Manufacturing Partner will produce the part or at what cost.

We are looking for a Senior Software Engineer who will design, develop, and maintain the systems that enable accurate, scalable, and reliable pricing across our product portfolio. In this role, you will own complex backend services at the intersection of business logic, data engineering, and platform reliability, directly impacting revenue outcomes and customer experience. You will also mentor other engineers, help shape architectural decisions, and work closely with Product and Data teams.

What you'll do:

Design and develop scalable, high-performance backend services for pricing, including rate engines, discounting logic, and billing integrations

Own the end-to-end software development lifecycle, including design, implementation, code reviews, testing, deployment, and ongoing monitoring of pricing systems

Partner with Product Managers, Finance, Sales, and Data teams to translate complex pricing strategies and business requirements into robust, maintainable solutions

Lead and influence architectural decisions while continuously strengthening the platform’s technical foundation

Establish and uphold engineering best practices, including code quality, testing approaches, and performance standards

Mentor and support mid-level and junior engineers, fostering growth and technical excellence within the team

Troubleshoot and resolve production issues, conduct root cause analysis, and implement long-term preventive solutions

Monitor system performance proactively, optimise query efficiency, and ensure pricing APIs consistently meet SLA targets

Enhance CI/CD pipelines, deployment workflows, and infrastructure-as-code practices to improve development efficiency and reliability

Work closely with stakeholders to ensure pricing systems remain compliant with relevant regulatory and business requirements

What it takes:

Bachelor’s degree in Computer Science, Software Engineering, Mathematics, or a related field (or equivalent practical experience)

7+ years of professional software engineering experience, with a strong focus on backend systems

2+ years of hands-on experience working with pricing, billing, payments, or financial systems in a production environment

Proven track record of leading technical projects and mentoring other engineers

Proficiency in Python and/or C# for designing, building, testing, and monitoring production-grade systems

Strong experience with relational databases (such as PostgreSQL or MySQL), including schema design, query optimization, and indexing strategies

Experience designing and developing RESTful and/or gRPC APIs for internal and external consumption

Solid understanding of distributed systems concepts, including eventual consistency, idempotency, retry strategies, and event-driven architectures
