The Opportunity:

We are looking for a Senior Frontend & Mobile Engineer with experience in Typescript/React, Swift and Kotlin to join our Data Products team at Snowplow. The Data Products team enables customers to rapidly create, govern, and iterate on high-quality behavioral data products that fuel AI-powered applications. We transform the complex process of data creation from weeks to days through intuitive design tools, automated code generation, and comprehensive governance capabilities.

We believe in supporting engineers to have autonomy and responsibility to make decisions, taking ownership of the product from technical design to code to customer. The ideal fit will be an engineer who loves to learn and take on new challenges, and can solve a variety of problems to ensure the success of the overall service, in partnership with our product and customer-facing teams.

If you are growth-oriented, passionate about technology, and excited about building exceptional UIs and complex business services, we want to hear from you

What you'll be doing:

• Working on our Typescript/React single-page application, as well as our mobile tracking SDKs and code generation tools (both iOS/Swift and Android/Kotlin)
• Embracing AI coding assistants to delegate the boring, repetitive tasks while focusing on the creative, important work. We believe in AI as an enabler of velocity improvements, while being cognizant of the constraints; and deploy its strengths intentionally
• Building robust QA, unit and integration tests
• Writing top documentation about the features you help deliver
• Taking turns to investigate our customers' escalated tickets and respond
• Collaborating in Scrum ceremonies and engaging with cross-functional teams for requirements
• Engaging with stakeholders for alignment on project goals and updates
• Researching new technologies to improve the Snowplow ecosystem

We'd love to hear from you if:

• You have professional experience building 1) engaging user experiences for the Web with Typescript and React; and 2) mobile applications -or, ideally, SDKs- with Swift and Kotlin
• You understand web accessibility standards
• You know what makes a library/toolkit/SDK robust and intuitive to use
• You have an array of tools under your belt to support making a web/mobile application faster and more accessible
• You place maximum emphasis on security. Data security and integrity are fundamental to what we do, so you'll need a solid understanding of security threats and how to overcome them

What We Offer You in Return:

A competitive package, including share options

Flexible working

A generous holiday allowance no matter where you are in the world

MacBook and home office equipment allowance

Enhanced maternity, paternity, shared parental and adoption leave
