Smartly is an AI-powered adtech company, enhancing marketer productivity and unifying the platform world.
The Role

We’re looking for a senior fullstack engineer to join team Chronos, building Smartly’s TikTok offering. 

Our TikTok product helps advertisers to create hundreds of variations of ads simultaneously using automation and publish them to TikTok in an easy, effective, and enjoyable way. In addition, our product allows reporting and automatic optimization of the same campaigns. 

TikTok is currently one of the key growth channels within Smartly. We are working on multiple exciting projects to keep up with the latest developments from TikTok, while also enhancing Smartly's value-added features. As a developer, you will play a crucial role in driving our mission to provide a seamless experience for our customers.

Team Chronos develops the product autonomously while working closely with the most advanced advertisers and our in-house campaign managers, who use the product we build, guaranteeing a quick feedback loop.

What we're working with & what you'll do...

The product consists of our own micro-frontend, which has many complex forms, developed with React and TypeScript, and a backend service to provide an API and background processing. The backend service runs in Kubernetes, is developed with Node.js and TypeScript, and uses PostgreSQL, Redis, and RabbitMQ. In addition, we're actively using a few libraries and services that were developed in-house. Scalability is at the center of everything we build to ensure that we can support growing advertiser needs.

On the frontend side, the challenges include making the process of creating templated ads as intuitive as possible while accounting for the complexities imposed by TikTok and maintaining a similar look and feel across platforms supported by Smartly. With the backend, we solve problems like ensuring the template engine scales while meeting constraints of the TikTok API, such as rate limits and validations. In addition to the above, you would be building APIs and helping other engineering teams to port their features to TikTok.

You will be able to heavily influence the development of the product and own the features end-to-end. Multiple teams are involved in different parts of the product development, and we strive towards effective cross-team communication and collaboration.

Who we're looking for...

We’re looking for a growth-minded person with good communication skills and the ability to work independently. We're also seeking someone with solid experience in our technologies: React, Typescript, Node, PostgreSQL, Kubernetes, or similar tools. We are a hybrid first company so the expectation for the role is that you are able to work from our Berlin office 3 days per week.

What We Offer You:
  • Inclusive Culture: Join a team of over 750 Smartlies representing more than 60 nationalities across 24 locations in 13 countries, we foster a culture built on trust, transparency, and open feedback.
  • Global Impact: Be part of a company making a global impact, directly influencing our customers and business growth.
  • Wellbeing Focus: Enjoy generous healthcare packages, mental health services, and a healthy work-life balance with paid holidays and family leave.
  • Total Rewards: Benefit from equity options, performance-based rewards, competitive compensation, and ample career development opportunities.
  • Hybrid Workplace: Experience the flexibility of a hybrid work model, balancing office and remote work, with the option to work abroad for up to 30 days.
