Job description

Join to apply for the Software Developer Python (NL Based) role at Ortec Finance

Code. Mentor. Collaborate. Join us to shape the future with Python, where your expertise will strengthen our technical capabilities and drive real impact. Let’s build what’s next, together.

What will you do as a Python Software Developer?

At Ortec Finance, we help financial institutions make better investment and risk decisions through advanced models and technology. Our Economic Scenario Generator is one of our core solutions - a sophisticated simulation framework that produces consistent, data‑driven projections of economic and financial variables. These scenarios support our clients in strategic decision‑making, risk management, and long‑term financial planning.

Why do we need a Software Developer Python?

The Scenario Analysis & Valuation (SAV) department at Ortec Finance is accelerating its innovation roadmap by developing the next generation of our Economic Scenario Generator – in Python! To help and enable the team responsible, we are looking for a Software Developer who can elevate our technical capabilities: someone who excels in production‑grade software development, cloud‑native architecture, and modern software engineering practices. The team collaborates closely with quantitative financial analysts, to translate complex mathematical models into robust, flexible, production‑grade software. As Software Developer, you play a key role in building scalable, reliable, and high‑quality systems that are both mathematically robust and technically excellent.

Introducing: Your Team!

The Quant Development team currently consists of 4 enthusiastic and highly educated professionals with a variety of backgrounds and experiences. With more than 30 people in the department, there is always someone to help you (personal initiative and helping each other is one of the core values of Ortec Finance we hold high).

What do we offer?

We offer you a challenging and rewarding role in a growing company, while being part of an inspirational global business with a lot of opportunities for personal and professional career development.

The salary range is € 70k – € 83k on a yearly basis (including variable pay, 13th month, holiday allowance) for a 40‑hour workweek, depending on your role, competency profile and experience.

In addition to a competitive salary, we offer you excellent benefits, including:

  • An open and inclusive work environment (including active staff association with a broad variety of activities, staff social events, annual summer, and Christmas party and much more) with inspiring, friendly, and enthusiastic colleagues.
  • Opportunities to develop yourself with a training program as well as weekly research and knowledge meetings.
  • Hybrid working (working from the office in Rotterdam with possibility to partly work from your home office).
  • One‑year contract with the prospect of a permanent position, because we strive for a long‑term collaboration.
  • A guaranteed 13th‑month salary, 8% holiday allowance, an attractive bonus scheme, participation in our competitive pension plan, reimbursement for commuting and other travel costs, a working from home allowance, a company laptop, and 27 vacation days with the option to buy more.
Who are you?

As a Software Developer, you are a team player with excellent communication and collaboration skills. You enjoy mentoring others in professional software development practices; growing a development team excites and motivates you! You have a sound understanding of mathematics and data science, and you are familiar with cloud platforms (such as Azure), and modern DevOps practices. And of course, you recognise yourself in our core values.

In addition, the following aspects are important:
  • Bachelor’s degree in computer science, Software Engineering, or a related technical field.
  • 3‑5 years of professional software development experience.
  • Strong proficiency in Python and its ecosystem (NumPy, Pandas, SciPy), being flexible to switch between paradigms and opinionated about them.
  • Strong proficiency in data processing.
  • Affinity or experience in quantitative finance, econometrics, or stochastic modelling is a strong plus.
  • This position is open to candidates who already have the right to work in the Netherlands.
Who are we?
