Fullstack Engineer

Mentimeter serves hundreds of millions of users with services that we deploy roughly 40 times a week. With transaction loads up to hundreds of votes per second, we have to be sure we can scale while still delivering a fast and smooth experience.

We work in small, independent, cross-functional and self-organizing teams. The team's product manager and the team work together to organize and plan the team's backlog with a focus on continuously delivering value to our users.

Please note that we are an English-first company, meaning you don't have to know Swedish to work here. Make sure your application and relevant documents are in English.

What you'll do

You'll be joining our Workplace Integrations team - a newly formed team focused on building the bridges that make Mentimeter indispensable within existing workplace ecosystems. We enable strategic integrations with platforms like Microsoft Teams, and Google Workspace that unlock value for both end users and enterprises, turning every integration into an opportunity for organizational growth.

On the Workplace Integrations team specifically, you'll design and build scalable integration architectures connecting Mentimeter with integrations that are the fabric of how companies operate. You'll ensure our integrations meet enterprise requirements for security, compliance, and reliability, while building monitoring systems to maintain high availability. You'll also create developer-friendly documentation and balance technical decisions that serve both immediate user needs and long-term scalability.

As a member of the team you'll contribute to strategic decisions about future integrations - building deep domain knowledge about the workplace ecosystem and contributing insights on which platforms will drive the most value for our users and business. You will do this with other engineers, a Product Manager, a Product Designer, and an Engineering Manager. Even though there are some specific roles in the team, we do things and solve problems together. We want you to be someone who engages with the rest of the team in product and design decisions and doesn't shy away from discussions.

Who you are

You are a reliable, high-performing individual contributor with a solid understanding of your area of specialization. You always have a good idea of what you want to do and then just do it. You embrace change and short feedback loops.

In addition to living up to our cultural values (see our Culture at Mentimeter section below), we hope you bring a passion for software development, scalable architecture, and building great products. For us, it is important that everyone cares about code quality, so an interest in testing and automation is needed. Excellent communication skills and working independently and in a team are other traits we are looking for in all our colleagues.

For the Workplace Integrations team, experience building integrations with third-party platforms or working extensively with external APIs is valuable. You should understand the complexities of distributed systems and async workflows, feel comfortable navigating technical documentation from various vendors, and have a security-first mindset, especially in enterprise contexts. You can balance perfectionism with pragmatism and are excited by making complex technical systems feel simple to end users.

Last but not least, you must have a curious mindset, be open to learning & sharing knowledge, and be interested in working with our tech stack.

The actual coding

The tech stack at Mentimeter consists of a frontend written in React (Next.js and Typescript), and a backend written in Ruby (not Rails). Supported by some of the following technologies:

Tailwind CSS

Node.js

Redis

PostgreSQL

Cloudflare

AWS

On the Workplace Integrations team, you'll also work with various third-party APIs and SDKs (Microsoft Graph, Slack, Google Workspace), OAuth 2.0 and other authentication protocols, webhook systems and event-driven architectures, and message queues for reliable async processing.

We require someone who knows React well but not necessarily Ruby for this role. If you know Ruby, that's great, but knowing another backend language well and being willing to learn Ruby is equally fine. It's more important to us that you have the right attitude than the exact right skill set.
