About MarkUp

MarkUp is the leading visual commenting platform for websites, PDFs, videos and images. It's the perfect companion in your creative process to bring teams together, helping close the feedback loop for anyone that works with multiple collaborators on a project.

Within just 5 years, we have signed up over 800,000 users and won Product Hunt Product of the Year in 2020. Our customers include some of the world's leading brands such as Verizon, Herbalife, Getty Images, BDO, Colliers, AIG, Rosetta Stone, Johnson & Johnson, and Dolby.

We are owned and operated by our parent company Ceros — a design platform that empowers the creation of bespoke, immersive digital experiences without code. As we share the same DNA as Ceros, we're also passionate about helping companies transform their approach to creating and managing digital content.

We are well-funded and institutionally-backed by prominent investors including Sumeru Equity Partners, Grotech Ventures, Greycroft, and Starvest Partners.

About the Team

As part of the MarkUp team, you'll be working with a small, cross-functional group of the most talented people you've ever worked with. We hire only passionate and creative people with a proven and unquestionable ability to execute, and every member of the team is equally responsible for moving the product forward.

We have a dynamic company culture that collaborates daily. We care deeply about the user experience, and we debate passionately about our ideas. When you work at Ceros, you check your ego at the door, and you aren't afraid to be honest, especially to yourself. We take our jobs seriously but ourselves not so much. As a member of a remote-first team, you embrace transparency and collaboration.

The Role

Building a product that can ingest and render well on any website is no easy task! We require the best-of-the-best, those who are ready to get creative and find solutions to complex problems across multiple browsers, stacks and platforms.

Our software engineers are all full-stack, able to handle whatever work comes their way. This role is no different, however, we anticipate the responsibilities being initially more backend and operations (DevOps) focused.

MarkUp is built upon TypeScript, comprising multiple services and packages, predominantly NodeJS based. We use libraries like React, Express, Lerna, Webpack and Jest. We believe in using the right tool for the job, our infrastructure runs on NodeJS, Redis, AWS Aurora, Kubernetes and Terraform within the AWS cloud.

Key Responsibilities

Writing well-architected, maintainable code (probably goes without saying)
Planning and leading high-complexity stories and epics
Reviewing story plans and offering insights on impacts to other parts of the application
Collaborating closely with the Quality Engineering team to write and maintain automated and regression tests, ensuring robust and reliable code
Participating in constructive code review sessions that focus on quality and productivity, while balancing the need to ship features in a timely manner
Focusing on delivering an exceptional user experience, with a strong attention to detail that reflects our commitment to creating intuitive and effective products
Participating as a primary on-call resource for service disruptions on rotation
Suggesting new technologies and techniques to improve engineer productivity
Collaborating with and mentoring your peers on security best practices
And finally, deploying your code to production and seeing the customer revel in feedback loop nirvana
Bonus Stuff:
Background in B2B or SaaS and Product-Led Growth Companies
Experience working in a remote-first environment
Practical stuff we anticipate you having

Track record of project ownership and exceptional product delivery
Competent in TypeScript, Node.js and SQL
Knowledgeable on best practices in back-end (specifically API) architecture
Experience working across a broad spectrum of the tech stack, with the ability to assist in tasks such as writing Terraform resources or creating GitHub Actions, in addition to a primary focus on backend development.

What we're looking for from the heart

You excel in navigating ambiguity, where complex and evolving requirements are more typical than clear-cut customer demands
You approach large challenges incrementally, preferring a test-and-learn methodology over prolonged heads-down development
You are self-motivated and proactive, with progress often driven by your own initiative and that of your team
Experience in a fast-moving startup environment desirable
You look to uplevel others around you, supporting teams outside of your specific project

This is a full-time position
This is a remote-first role, working hours aligned with European time zones
