đ Ă propos de nous
sunday is building the fastest, simplest way to pay in restaurants. With a quick scan of a QR code, diners can pay, tip, and leave in about 10 seconds. We believe great products should feel obvious, not complicated, and we focus relentlessly on keeping things
simple
while earning
trust
from restaurants and guests at every interaction. Today, sunday powers payments in thousands of restaurants across the US, UK, and France, helping operators turn tables faster, increase tips, and unlock valuable insights. We push ourselves to go
beyond
whatâs expected, building with ownership, moving fast, and scaling with ambition as we tackle our biggest growth opportunity in the US.
About The Role
As an EU Innovation & Exploration Junior Associate, youâll join sundayâs European Innovation Lab within the Central Operations team.
Your mission will be to help us understand and solve the biggest barriers to the adoption of sunday in restaurants. Youâll work at the intersection of field operations, Product, Data and Strategy, starting with real-world observations and ending with experiments, evidence and scalable solutions.
This is not a traditional internship focused on observation or coordination. Youâll spend significant time in restaurants with owners, managers, staff and guests. Youâll identify friction points, formulate hypotheses, support the design of prototypes and help run experiments in the field.
This is a hands-on internship within the European Innovation & Exploration Lab, focused on turning field observations into experiments, evidence and scalable solutions.
In this role, youâll take ideas from ambiguity to evidence. Youâll learn through doing and help us decide what to continue, pivot, scale or stop.
Youâll report to the EU Innovation & Exploration Lead and work closely with Country Operations, Product, Data and Commercial teams. With the support of the team, youâll have the opportunity to own selected topics from the first observation in the field to the final recommendation.
This internship is a great opportunity for an entrepreneurial person who wants to learn quickly, operate close to customers and have a direct impact on how sunday evolves operationally and how it impacts restaurants.
At the end of the internship, there may be an opportunity to join sunday full-time, depending on your performance, mutual fit and business needs.
Duration: 6 months, starting 1st of January 2027
Key Responsibilities
- Stay close to the field: Spend time in restaurants with owners, managers, staff and guests to understand how sunday is used in real-life conditions and where friction occurs.
- Identify adoption barriers: Observe and analyse the operational, behavioural and product-related issues that may prevent restaurants and guests from fully adopting sunday.
- Turn observations into hypotheses: Structure your field learnings, identify root causes and help translate observations into clear problems, opportunities and testable ideas.
- Support the design of experiments: Help imagine practical pilots, prototypes and operational tests that can help us understand which levers could improve adoption.
- Run experiments in the field: Coordinate with restaurant teams and internal stakeholders to launch tests, monitor their progress and make sure experiments are executed properly.
- Own selected topics end-to-end: With the support of the Innovation & Exploration Lead, take ownership of selected experiments from defining the objective and success criteria to analysing the results and sharing a recommendation.
- Create evidence through execution: Analyse what worked and what did not, combine qualitative and quantitative insights, and help the team learn quickly from each experiment.
- Report clearly on your findings: Prepare concise and structured updates on ongoing tests, key learnings, next steps and recommendations on what to continue, pivot, scale or stop.
- Help scale what works: Work with Product, Data, Operations and Commercial teams to turn validated experiments into repeatable processes, product improvements or commercial initiatives.
