About Ceros

At Ceros, you will help ambitious brands create digital experiences that people actually want to explore. Our platform gives marketers and designers the flexibility to design, build, and publish immersive content. All without code. With Ceros, teams move faster, scale smarter, and deliver work that makes a real impact. Customers report engagement times that are 80% longer and conversion rates more than 20% higher on Ceros-built experiences. That kind of performance is why leading brands like Workday, Colliers, and McKinsey rely on us. Working here means shaping the future of digital experiences and joining a team that values bold ideas, creativity, and purpose-driven work.

About the Team

As part of the Ceros Product team, you will be working with a small, cross-functional group of the most talented people you have 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. We care deeply about craft, but we optimise for impact. That means keeping things simple, making pragmatic trade-offs, and building, testing, and iterating quickly based on what actually works for our customers.

The Role

Designing and building the Ceros platform is an ambitious task. We require the best-of-the-best Software Engineers, Designers, and Quality Engineers, ready to build a best-in-class web content design studio, often pushing web browsers to the limits of what is currently possible. 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 frontend focused. Working with Software and DevOps Engineers, you will be focused on internal developer efficiency, tackling initiatives such as build time reductions, local development environment improvements, and API refactoring. We are refactoring a key part of our product to introduce new features that will help our customers take their content creation to the next level. This is a greenfield project focused on innovating a specific component of our product, not merely replicating it. As a candidate, you would be joining one of our modernization teams dedicated to this refactor, playing a crucial role in shaping the future of our product. Our technology stack includes Web Components, React, NextJS, AWS Aurora, Yjs, Terraform, Docker, GitHub Actions, and WebDriver.io, among others. While we are driving this innovation, we remain committed to preserving the strengths and stability of the existing product.

Key Responsibilities

• Writing well-architected, maintainable code, with a focus on solving real user and business problems
• 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, without losing sight of shipping and making progress
• Focusing on delivering an exceptional user experience, with a strong attention to detail that reflects our commitment to creating intuitive and effective products

Practical stuff we anticipate you having

• Track record of project ownership and exceptional product delivery
• Experience in successfully delivering multiple projects, owning both the technical leadership and direction

• Experience working across a broad spectrum of the tech stack, with the ability to assist in tasks such as writing Terraform resources, creating GitHub Actions, or developing API endpoints, in addition to a primary focus on frontend development.
• Experience working on realtime applications, examples of which include no-code/whiteboarding/collaboration platforms, visualisation tools, 2D/3D applications in the browser, etc.

What we are 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
