**Who We Are

Float is the world’s leading software for teams to plan their time. Launched in 2012, we’ve grown every year since, and remain proudly independent, self-funded and profitable. As a certified B Corporation, we’re committed to making a positive contribution to our team, customers, the environment, and the remote community. We’re a team of 50 working 100% remotely who believe in living our Best Work Life. You’ll partner with team members globally, including Australia, Mexico, Italy, Nigeria, Canada, and the USA. Hear what our team has to say by browsing our blog, or reading our Glassdoor reviews. Check out what our customers think of Float from our G2 reviews.

We’re on a scale up journey, and we’re seeking people who thrive in this stage, given the autonomy, and the opportunity, to do the best work of their career.

**Why We’re Hiring For This Role

Our front-end team is responsible for our customer-facing application, the primary way customers get value from Float. We support a web application, an iOS app, an Android app, and a desktop app (Electron). All these platforms share a considerable amount of code and are continually growing.

As our product continues to grow, our customer base grows with it. We are seeking a skilled engineer to help move things forward by building new user-facing features, contributing to our shared component library, and modernizing legacy code. The Senior Interfaces Engineer will also be responsible for the coverage and maintenance required to ensure that we can deliver the high-quality experience that our customers expect from us.

You’ll join a smart, capable group of engineers specifically focused on the web application, ensuring that the primary vehicle to deliver value remains exactly that. We have some ambitious goals as a company and in order to fulfill them, we have some equally ambitious goals for our web application. We’re keen to be able to support our customers as they become more successful and grow, and this ever-increasing growth is starting to challenge some of our older systems. We’re eager to reimagine our front-end to support customers whose sizes exceed our current largest customers.

Our Lead Interfaces Engineer, Haakon Jack, explains the important role you will play within our Interfaces team. **Watch this video!

You’ll be working asynchronously with a bright, dedicated team from across the globe, with a strong focus on taking complex problems and creating solutions that feel simple and intuitive for our customers.

**What You’ll Be Responsible For

Early on, you’ll jump right into:

• Leading Product-Focused Projects: Drive projects such as enhancing charts/visualizations or improving onboarding experiences.
• Stakeholder Communication: Discuss specifications with Product and Design teams to understand problems and constraints, especially performance-related ones.

Once you are a bit more settled, we expect that you will jump into:

• Specializing in Application Areas: Focus on specific parts of the front-end architecture, handle regressions, bugs, and customer queries related to those areas.
• Contributing to the Front-End Architecture: Participate in discussions on scaling and evolving the front-end architecture, including strategic changes or process improvements.
• Contributing to the Design System: We use an internal design-system/component library at Float to keep our UI’s consistent and high quality – you’ll be expected to work with the Design Platform team to add and update components as needed for feature work.
• Cross-functional Collaboration: You’ll collaborate with various teams across engineering and Float; for example, engaging with the User Experience team to understand and improve how customers interact with the product, ensuring it meets their needs.

**What You’ll Need To Be Successful

We want you to love your work and believe that these skills will allow you to succeed in the role. Applying these skills requires:

• React Expertise: High level of proficiency in React, with a strong understanding of hooks
• State Management: Experience building large applications with Redux, good understanding of local vs. global state
• Styling Approach: Familiarity with Vanilla CSS as well as CSS-in-JS, without reliance on utility classes like Tailwind
• Typescript: Experience with TypeScript, as we are currently transitioning our front-end codebase to Typescript
• Testing Tools: Knowledge of Vitest or Jest for testing
• Monorepo Experience: Comfortable working in a monorepo environment
• Bonus if you come to us with:
  • Experience with End-to-End test automation system
  • Experience building Design Systems as a means to bridge the gap between design and development
  • Building Android and iOS apps with React Native
  • Working with distributed systems and event-based architectures at scale

As a fully remote team, we’re looking for someone comfortable with asynchronous communication as the default, which means you have previous remote experience and are comfortable using tools like Slack, Loom, and Linear to communicate as needed. Don’t worry—you will have significant deep work time since we have very few meetings.

**Why Join Us

Pay for this role is US $167,471 (Level 3). Here’s a blog post with more information on how we determine our salaries.

We’re a global async remote company with a erse team of people from all over the world who share a common belief in living our best work life. We believe deeply in the idea of transparency and share our Float Handbook publicly so potential new team members can see first hand our perks & benefits as well as our ways of working. If you feel like you can thrive at Float to do your best work, we would love to hear from you.

**Hiring Process For This Role

You’ll find a lot of useful information about our interview process and what it’s like to join our global team on the Float careers page. The hiring process for this role looks like this:

• Initial First Meet (20 min): You'll meet with Julia Fulton, Talent Manager, to discuss your interest in the role and review your questions about working at Float.
