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

What We Do
Protolabs is the world's fastest digital manufacturing source for rapid prototyping and on-demand production. The technology-enabled company produces custom parts and assemblies in as fast as 1 day with automated 3D printing, CNC machining, sheet metal fabrication, and injection molding processes. Our digital approach to manufacturing enables accelerated time to market, reduces development and production costs, and minimizes risk throughout the product life cycle. 3D Printing Our 3D printing service offers a wide selection of materials and technologies to create prototypes and end-use parts with complex geometries and detailed features. With tight process controls, careful design reviews, and extensive quality monitoring, we ensure precise and repeatable 3D-printed parts, every time. CNC Machining We use 3- and 5-axis milling along with turning to machine parts from commercial-grade plastics and metals. Our online quoting system and automated manufacturing process enable us to ship parts within 24 hours, helping customers accelerate development and reduce time to market. Sheet Metal Fabrication Protolabs is an industry leader in quick-turn sheet metal parts for both prototyping and low-volume production. Our digital approach to manufacturing enables us to fabricate sheet metal parts in as fast as 5 days. Additionally, we can support our customers’ development efforts with component assemblies, several finish options, and screen printing. Injection Molding Our injection molding service offers two options—prototyping and on-demand manufacturing—which provide customers a tooling solution that aligns with their project’s requirements. It’s used for quick-turn prototyping, bridge tooling, and low-volume production of up to 10,000+ parts in 15 days or less.
