Qpurpose ApS
Odense M

Qpurpose is looking for one Algorithmic Software Engineer to join our team. Whether you have just graduated from university or have many years of experience, this position offers a unique blend of classical programming and software development within a quantum computing framework.

You will develop efficient, production-grade systems using C++ for computationally intensive applications. These include real-world use cases across industries, with future opportunities to integrate quantum computing techniques. This role is ideal for engineers passionate about performance, systems-level programming, and scalable algorithm implementation.

At Qpurpose, we work with partners in finance, health and life sciences, meteorology, and renewable energy systems.

  • Start date: As soon as possible
  • Location: Odense, University of Southern Denmark
  • Employment type: Permanent

What you’ll do

  • Design and implement high-performance algorithms, data structures, and backend systems in C++.
  • Optimize computational performance for data-intensive and latency-sensitive applications.
  • Develop scalable solutions across domains such as machine learning, optimization, computational biology, finance, and logistics.
  • Collaborate with Python-based systems and pipelines when relevant.
  • Communicate assumptions, tradeoffs, and limitations to both technical and non-technical stakeholders.

What we’re looking for

  • A Bachelor’s or Master’s degree in Computer Science, Mathematics, Physics, Engineering, or a related technical field.
  • Strong C++ programming experience (preferably 2+ years in production, HPC, or performance-critical systems).
  • Excellent algorithmic and analytical problem-solving skills.
  • Strong sense of ownership and the ability to independently drive projects forward.
  • Ability to quickly learn and adapt to new technical domains.
  • Strong communication skills and the ability to explain complex systems clearly.

Bonus points

  • Ph.D. in a relevant technical field is considered a strong plus.
  • Experience integrating C++ with Python (e.g., bindings, hybrid systems).
  • Experience working with sensitive data or secure environments.
  • Familiarity with DevOps practices, CI/CD pipelines, and reproducible deployments.

What we offer

  • Challenging software engineering work on real-world algorithmic problems with impact across industry domains.
  • Close collaboration with researchers, engineers, and industry partners across areas such as finance, life sciences, meteorology, and renewable energy.
  • Access to advanced mathematical expertise, modern computing resources, and interdisciplinary collaboration.
  • A competitive salary package, including pension and standard employment benefits.
