Senior Fullstack engineer

Mentimeter is an engagement tool with a clear goal in mind. To turn presentations into conversations. Through real-time interactivity and clear visualizations, we get people to participate, engage and become more productive. Transforming all those passive meetings, airless classrooms and drawn out trainings into valuable and memorable moments.

We truly believe that you achieve the best results by doing things together. And that successful leaders need to adopt a curious and collaborative mindset in order to get there. So with you at Mentimeter, you'll be a big part of the ambition to help over 1 billion people listen, learn and work better together.

We're looking for a
Senior Fullstack Engineer
to help us shape the future of audience insights at Mentimeter. Join our Results team and play a key role in delivering AI-powered, meaningful results to millions of users.

The team
The Results team builds how users experience the outcome of a Mentimeter session. Our focus is on helping users understand and learn from the input they collect, whether it is instant feedback during a presentation or insights that develop over time.

We are enhancing the presentation and interpretation of results, and exploring how AI can assist users in understanding their data more effectively. Our goal is to make it simple for anyone using Mentimeter to draw conclusions, share learnings, and take action based on their results.

The Results team, together with our sister team Recommendation Engine, forms our Insights area. In this area, AI, and more specifically, leveraging AI to build a product, is a significant part of what we spend our day-to-day on.

Who You Are

• Minimum 8 years of experience as a software engineer, with solid understanding of product development.
• Likely holds a Master's degree in a relevant engineering field.
• Interested in AI and eager to learn and experiment with how it can elevate user experience.
• Experience with Python, LLM integrations, or prompt design is a plus (not required).
• A reliable, high-performing individual contributor with strong ownership and initiative.
• Comfortable with change and short feedback loops.

• Passionate about:

• Software development

• Scalable architecture

• Code quality, testing, and automation

• Excellent communication skills; able to work both independently and collaboratively.

• Brings a curious mindset and a willingness to learn and share knowledge.

Tech stack & tools

• Frontend: React , TypeScript)
• Backend: Ruby (not Rails)
• AI: SQS-driven Python service, using OpenAI as the LLM provider.
• Other technologies: Tailwind CSS, , Redis, PostgreSQL, Cloudflare, AWS

For this role, we don't necessarily require someone familiar with Ruby. If you know Ruby, that's great, but knowing another backend language well and being willing to learn Ruby is equally acceptable. It's more important to us that you have the right attitude than the exact right skill set.

How We Work
We work in small, independent, cross-functional, and self-organizing product teams. A team consists of a product manager, an engineering manager, a product designer, and engineers, all of whom focus on continuously delivering value to our users.

We're looking for someone who actively engages in product and design discussions, contributes ideas, and isn't afraid to challenge the status quo. This role is for someone who wants to do more than write code for eight hours a day - it's for someone who wants to build a company and a product.

To be successful, you should enjoy the entire product development chain, from ideating brand new ideas and breaking down designs into feasible work, through writing and testing the code, to ensuring it is efficiently deployed to production. This means that a reasonable amount of context-switching will be expected from you during our sprints.

As a senior software engineer, delivering value to our users is essential. But an equally important task is to scale and help your juniors. To succeed in this role, you must enjoy mentoring others and getting motivated by seeing them grow not only as developers but as engineers driving the product forward.
