Staff Engineer – Fluid Dynamics Solver Development
Synopsys / Ansys Aqwa Team – Remote
We are Synopsys, the leader in engineering solutions from silicon to systems. We enable customers to rapidly innovate AI-powered products through silicon design, IP, simulation, and analysis solutions. We partner closely with industries to maximize R&D capability and productivity, driving innovation that shapes the future of engineering.
You are You’re a computational fluid dynamics (CFD) subject matter expert who treats numerical simulations as solvable, real-world problems—not academic exercises. Your work revolves around translating complex physics into production-grade Python and Fortran code that delivers physically accurate results.
You don’t wait for perfect specifications. When a research problem lands on your desk, you:
- Research the latest literature and consult domain experts to determine the true requirements.
- Reverse-engineer legacy code (Python, Fortran, or beyond) to understand and extend functionality.
- Prioritize code usability over rote efficiency—clear variable naming, modular logic, and robust documentation come naturally.
Your expertise bridges rapid prototyping in Python and high-performance Fortran, as you know when each language excels. You balance accuracy, stability, and performance in solver development, ensuring outputs align with real-world fluid behavior.
Responsibilities
Design and implement novel simulation features for CFD solvers, including:
- Translating research concepts into production-ready code that models turbulence, boundary layers, and multiphase flows
- Developing and optimizing numerical solvers for various flow regimes (e.g., marine hydrodynamics, coastal engineering)
- Building unit and integration tests to validate against analytical solutions, experimental data, and established benchmarks
- Tracing and resolving defects in legacy Fortran-based simulation pipelines
- Writing technical documentation (e.g., solver design rationale, method validation) for fellow engineers
- Prototyping new computational methods by reviewing literature and assessing practical feasibility
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
Collaborate with R&D teams and domain experts to integrate solver components into multi-physics simulation workflows, advancing:
- Offshore wind platforms
- Wave energy systems
- Marine structures—directly supporting the transition to renewable energy.
Impact
Your contributions will enable game-changing advancements, including:
- Expanding simulation capabilities for industries that previously lacked computational tools (e.g., aquaculture, renewable marine energy).
- Reducing runtime (from days to hours) to accelerate high-stakes design decisions.
- Building trust in simulation-driven engineering through defect resolution and validation studies.
- Democratizing access to reliable tools via clear documentation and robust architectures.
- Pushing the envelope in AI-accelerated CFD as the team explores next-generation methodologies.
Requirements
You bring a blend of research expertise and engineering pragmatism:
- PhD in engineering, physics, applied mathematics, or related scientific discipline, with hands-on CFD, numerical methods, or computational fluid dynamics experience.
- Proficiency in Fortran and Python, with experience writing production-quality code for scientific computing (e.g., numerical PDE solvers, parallel computing).
- Strong grasp of:
- Discretization schemes (e.g., finite volume, finite difference)
- Numerical stability/accuracy principles
- Boundary condition formulation
- Full software development lifecycle experience:
- Version control (e.g., Git)
- Testing frameworks (e.g., pytest in Python)
- Debugging tools and contemporaneous documentation practices
- Domain fluency in fluid dynamics or rapid learning ability to bridge gaps with physicists/engineers.
- Plus factor: Experience in marinehydrodynamics, offshore engineering, or renewable energy simulation.

Who You Are
Your strengths lie where technical depth meets problem-solving agility:
- Debugging legends: You can dissect a physics bug in legacy Fortran, reproduce it in tests, and explain root causes to both support teams and domain experts.
- Code archaeologists: You approach outdated implementations with curiosity, extracting intent to refactor or extend—without frustration.
- Commitment-first: You write tests and docs simultaneously, not as afterthoughts.
- Ownership mindset: You’ll validate your work and iterate based on customer feedback, ensuring solutions meet real-world needs.
- Dual aptitude: You comfortably transition from technical discourse about solver implementations to customer-facing training on simulation setups.
The Team
This Staff Engineer role will integrate into a remote-focused R&D team of four engineers at Ansys Aqua, dedicated to advancing fluid dynamics tools. Your work builds Aqwa’s solver pipeline, impacting customers in:
- Renewable energy (wave/aquatic turbines)
- Aquaculture infrastructure
- Coastal and marine engineering.
The team directs the long-term technical evolution of Aqwa, helping it scale to complex, real-world challenges.
Rewards & Benefits
- Comprehensive benefits (health, wellness, financial accounts) to support your holistic well-being.
- Dynamic ways: Your recruiter will provide salary insights and benefits details during the interview process.
