SessionLab is the leading platform for workshop facilitation and process design. Our mission is to empower people to create change. We do that by building technology that enables better facilitation. More than 100.000 professionals are using our Software-as-a-Service product to design and deliver meaningful workshops.  We are looking for a senior full-stack developer with frontend-focused experience to help us scale our platform and deliver more value to our customers.  You’ll be our fourth developer, working closely with our Tech Lead and other developers, as well as our designer and product manager. You’ll build new and exciting features, improve platform security and maintain the stability of our infrastructure. You will have a chance to work on and influence our whole stack, with an initial focus on the front end.  We are a bootstrapped and profitable software business, headquartered in Tallinn, Estonia, and working across Europe with a fully remote 10-person team (team members currently in Sweden, Hungary, Croatia, UK, Austria, Portugal, and Italy). Therefore, we are looking for somebody who is self-motivated, independent, and comfortable working in a remote-first environment. What we are looking for 

  • You have deep React knowledge and experience.

  • You excel at CSS and enjoy developing Design Systems.

  • You have experience with building REST APIs (ours is built on Rails). 

  • You are comfortable building full-stack features from scratch. 

  • You are comfortable working in a small startup where cross-discipline work is encouraged. 

  • You are good at problem-solving critical production issues in a timely manner. 

  • You seek to take on responsibilities and take ownership of the work you do. 

  • You thrive working independently, but also enjoy collaborating with people from different disciplines and you always try to look at the big picture. 

  • Experience working remotely. 

  • You are based within UTC-8 and UTC+3 and have a few work hours overlap with 8 am to 3 pm UTC 

Advantages (not a must but a big plus) 

  • Experience with technologies in our stack (Mobx, Rails, Webpack, PostgreSQL, Pusher). 

  • Experience with UX/UI design and prototyping. 

  • Experience in working on real-time sync in collaborative applications. 

  • Experience in scaling web applications and optimizing frontend code. 

  • Experience with workflow tools (Github Actions, Sentry, Mixpanel, Jira). 

  • Experience with deploying production grade systems on Amazon Web Services (EC2, CloudFront, S3). 

  • Contribution to open source projects. 

  • Experience with maintaining WordPress. 

What will I be doing? To give you an honest perspective of where we are now: we have a stable application and infrastructure with a relatively up-to-date codebase and an extensive customer-driven roadmap of new features and improvements we want to bring to the app.  This is where you come into the picture: we need somebody who can work full-time on bringing new features and improvements to the app.  In more practical terms:  

  • Building new features that have frontend or full-stack requirements. 

  • Work with our designer to define and maintain a consistent Design System. 

  • Debugging production-related issues. 

  • Improve front-end performance. 

  • Working with our designer to provide technical input on new designs. 

  • Working with the Tech Lead and the other developers to improve the developer experience. 

  • Scaling the infrastructure. 

Why is this great for me? 

  • Opportunity to get involved early in building and scaling a product in a fast-growing market. 

  • Your role and responsibility will grow as our company grows. 

  • Work remotely and create your own schedule (we believe in trust and autonomy). 

  • A stable working environment that values work-life balance. 

  • Motivated co-workers. 

  • You will also have a chance to travel a couple of times per year to live company meetings (pandemic permitting 😕). 

  • An open-minded working culture where we encourage sharing opinions and feedback. 

  • You are passionate about building stable apps that provide great user experiences. 🙂
