Join Pigment: Transforming Business Planning and Performance with AI

Pigment is the AI-powered business planning and performance management platform built for agility and scale. We connect people, data, and processes in one intuitive platform, with AI agents that work alongside every team, from Finance to HR, to build, adapt, and align strategic plans in real time.
Founded in 2019, Pigment is one of the fastest-growing SaaS companies globally, passing $100M in ARR in 2026 and doubling revenue for the second year in a row. Industry leaders like Unilever, Uber, Anthropic, Snowflake, and Siemens use Pigment every day to make better-informed decisions and navigate any scenario with confidence.
In October 2026, we raised a $250M Series E at a $2.3B valuation, bringing our total funding to $650M+. Today we’re a growing team of 700+ across Paris, London, New York, Toronto, San Francisco, and Austin, and we’ve been named a Visionary in the Gartner® Magic Quadrant™ for Financial Planning Software two years running.
At Pigment, we take smart risks, celebrate bold ideas, and challenge the status quo - all while working as one team. If you’re driven by innovation and ready to make an impact at scale, we’d love to hear from you.

🚀 The Opportunity:

As a Fullstack Software Engineer you’ll work on performance-critical systems that process and aggregate millions of records in real time, directly enabling our clients to make better, faster decisions. Your role will be mostly working on backend in C#, with some frontend in React.

Here’s why this is an exciting opportunity:

✨ Work on the Core Engine: Contribute to the design and optimization of our proprietary formula and query engine.

⚙️ Solve Complex Problems: Tackle scalability and performance challenges across high-volume, real-time datasets.

🧠 Shape the Product: Collaborate closely with frontend engineers and product managers to deliver impactful features.

🚀 Own the Stack: Build and maintain backend services using modern technologies like .NET Core, PostgreSQL, React, and GCP.

📈 Drive Innovation: Influence architecture decisions, test new ideas, and continuously improve performance and reliability.

If you enjoy solving hard problems and building systems that scale, this is the perfect place to grow your career!

Our Engineering team

Our Engineering team is responsible for developing our SaaS platform and building a comprehensive and user-friendly product.

Pigment engineers participate in the entire application development lifecycle, focusing on design, coding and keeping the production platform up and running. They can be specialized, but there is no strict separation between the backend and the frontend.

We value user-centricity and pragmatism: we choose the most relevant tools for the problem we have to solve, understanding the strengths and constraints of each technology.

Our engineering culture also values curiosity, humility, trust, ownership and team spirit.

Our technical stack is C# on .NET Core Linux, React, TypeScript, PostgreSQL, Google Cloud Platform, Docker, Kubernetes, Terraform, RabbitMQ and Circle CI.

Who you are

More than knowledge of a specific language or framework, we are looking for great software engineering skills: ability to translate functional requirements into an elegant and simple design, and then deliver the code.

We are also looking for engineers who understand the product and the customer's needs in detail and can suggest innovative ideas: in the end, it's all about delivering value to end users.

In any case, you have:

- Proven experience designing object oriented software with languages such as C#, Java, C++, Golang, Rust, Python or Ruby (this list is not exhaustive).

- Proven experience with JavaScript, CSS and JavaScript libraries or frameworks such as React, Vue.js or Angular.

- Great team spirit with a problem-solving attitude.

- A good dose of humility and the willingness to grow (no matter your seniority!).

- A fluent level in English (French is not a must).

Folks from underrepresented minorities: science shows that you are less likely to apply if you feel that you don’t have all the necessary prerequisites. If this description matches where you are now or what you'd like to grow into in your next position, we encourage you to apply.

What you will get

- Competitive salary

- Equity

- The best health insurance with Alan Blue entirely free for you and your family 💙

- Trust and flexible working hours

- Brand new offices in the heart of Paris, London, New-York and Toronto
