Software Developer – Particle-Based Methods

COMSOL, Inc. is looking for a software developer to strengthen the development team in its Burlington, MA office. We are seeking an individual with a solid background in particle‑based numerical methods. In this role, you will enhance and extend our Particle Tracing Module, Granular Flow Module, and Molecular Flow Module — add‑on products to COMSOL Multiphysics®. You will contribute across the full development lifecycle — from problem analysis and specification, through implementation in C++/Java, to testing, documentation, and product design.

This role offers the chance to help shape new industry‑relevant simulation features and tools.

• Collaborate with team members to analyze simulation requirements and define technical specifications.
• Design and implement robust, efficient numerical methods and simulation algorithms in C++ and/or Java.
• Conduct testing and verification of code, produce clear documentation, and ensure maintainability of the software modules.
• Participate in product design and innovation for simulation software applied to real‑world engineering problems.
• Work with cross‑discipline teams to deliver impactful solutions.

• Ph.D. in Applied Science or Applied Mathematics.
• Expertise in at least one of the following numerical simulation methods:
  • Lagrangian particle tracking
  • Discrete element method (DEM)
  • Molecular dynamics (MD)
  • Smoothed particle hydrodynamics (SPH)
  • Particle‑in‑cell (PIC)
• Demonstrated experience with mathematical modeling.
• Proven programming experience in C++/Java.
• Excellent technical writing skills.

• Experience with COMSOL Multiphysics.
• Experience with user interface design and development.
• Familiarity with the finite element method (FEM) and multiphysics coupling.

• An exciting opportunity to deepen your knowledge across a range of physics application areas and engineering domains.
• A team of creative, skilled, highly experienced professionals in a fast‑paced, high‑tech simulation software company.
• Excellent career growth potential as we expand our simulation software offerings.
• Compensation commensurate with skills and experience.
• Health and 401(k) plans with a company match and other benefits.
• Generous vacation time.
• A spacious, bright, and comfortable office with private work spaces.
• A surrounding office park with onsite restaurants, hotels, bars, and a free fitness center with workout classes.
