Today's engineering organizations building cutting-edge products and advanced systems must deliver increasingly complex solutions faster than ever, often with lean teams and no room for error. nTop changes how engineering gets done. Our technology collapses months of iteration into hours, letting teams explore thousands of variants instead of settling for the first option. Teams reduce development time by 50% and increase program win rates. Leaders choose nTop when failure isn't an option.

As a key member of our development team, you'll play a central role in evolving our implicit modeling software to meet the demands of modern computational design workflows. Your primary focus will be developing new features that seamlessly integrate our platform with a broader ecosystem of tools, enabling users to work more efficiently across their entire design process.

Does this sound like you? nTop is hiring a Senior Software Engineer C/C++ for building cutting-edge implicit modeling software. This role is remote in either Germany or the UK, and reports to the Engineering Manager of the Build team.

What You'll Do

  • You'll own the design, implementation, and delivery of the APIs that connect our implicit modeling and simulation application with the ecosystem of tools our customers use to map their workflows—from third-party enterprise systems and automation scripts to custom integrations and ML/generative AI training pipelines. These APIs integrate directly with our core geometry and modeling system as well as our UI layer. You'll own critical parts of these systems and collaborate closely with engineers focused on the core engine and UI development. As technical owner of these strategically critical interfaces, you'll understand customer workflows, identify integration opportunities, and translate requirements into robust, scalable C/C++ solutions.
  • You'll work within an established desktop application codebase while helping modularize it toward a more open, service-oriented architecture. This means balancing the immediate delivery of user-facing features with thoughtful consideration of long-term architectural improvements.
  • You'll participate in technical design discussions, code reviews, and knowledge-sharing sessions, helping to elevate the team's collective expertise and establish best practices for integration development and architectural modernization.

Required Technical Skills

  • 5+ years of professional C/C++ development with strong command of modern standards (C++11/14/17), object-oriented design principles, and design patterns
  • Proven experience working with large-scale C++ desktop application codebases (100k+ lines) and diagnosing complex issues in production environments
  • Deep understanding of memory management, multithreading, and performance optimization
  • Experience working in cross-functional teams with established software development processes, including testing practices and QA handovers

Preferred Experience

  • Background in software architecture modernization projects
  • Experience with building compilers
  • Experience migrating monolithic applications to distributed systems
  • Knowledge of computational geometry or geometric algorithms
  • Knowledge of functional programming principles
  • Understanding of architectural refactoring strategies
  • Familiarity with technical debt assessment and refactoring strategies
  • Understanding of CAD/engineering software workflows
  • Experience in decomposing large-scale applications into service-oriented architectures
  • Exposure to containerization technologies (Docker, Kubernetes)
  • Familiarity with service-oriented architecture (SOA) and microservices patterns
  • Experience with API design and RESTful services
