Frontend engineer

As our core tech team is based in Paris, we prioritize engineers based in Paris region that can come 3 days / week at the office for now. It might change in the future.

You don't have to match 100% of the requirements. If you believe you're a strong fit, we'd love to hear from you.

We just raised $35M in Series A, if you join Tsuga you will experience a strong growth.

About the role & the team

You will join the web team composed of 6 engineers, mainly based in Paris with a couple of remote workers.

As a frontend engineer at Tsuga, you will face very interesting technical challenges inherent to observability and early-stage such as:

• Building simple, ultra-fast interfaces for complex problems
• Querying and visualizing petabytes of data
• Pushing React/TypeScript and frontend performance to their limits
• Designing performance-oriented solutions designed to handle and display large volumes of data beyond the native capabilities of web browsers
• Optimizing front-end performance to ensure fast load times and a smooth user experience
• Working on huge product surface area: design systems, complex visualizations, flow builders, investigation assistants, etc.
• Being pragmatic and able to deploy working code into production, even if it’s not perfect, to maintain our development velocity (code pushed into prod every 6h, 1 week sprint)

Our technical stack:

• Typescript, React
• Recharts, Tanstack query & tables
• ChakraUI for the design system
• CI / CD in Github actions, Playwright and Vitest
• Any AI you like to use to help make your job easier

About you & what we are looking for

• At least 5 years of frontend experience in highly technical environment
• Previous experience in building data-driven applications, including visualizations and dashboards
• Knowledge of observability is a huge plus but not mandatory
• Strong knowledge of HTML, CSS, JavaScript, and modern frameworks (React, Vue, Angular)
• Knowledge of web performance

Perks & benefits

• Lunch vouchers (Swile)
• Health insurance (Alan)
• Unlimited snacks at the office
• Referral allocation 5k€
• Meaningful equity
• Quarterly team offsite in France - the whole company, every quarter
• Parental leave: fully paid parental leave policy, 32 additional company-funded days for the non-birthing parent with flexible usage options
• Remote friendly: we have a lot of full remote workers and for others based in the Paris office, we expect them to come 3 days per week at the office

Working at Tsuga

• We move fast. As an early-stage startup, we value ownership, and quick feedback over unnecessary process and hierarchy.
• We solve problems, not blame people. When something goes wrong, we fix it, learn from it, and improve the system.
• We are builders. We start everything from a blank page and we lean on your colleagues' knowledge to move faster.
• We are customer-obsessed. We dogfood Tsuga every day, so you care how the product is actually used and want to contribute ideas.
• We lean hard on AI, but not blindly. Our problems are hard and can’t be AI-slotted away.
• We’re international from day one. Every quarter, the whole team meets at our French office to align on company goals, celebrate wins, and connect with teammates from the US, UK, the Middle East, and across Europe.
