The role
As a Senior Full-Stack Engineer, you will play a crucial role in Team Acquisition. Your role will be to build and optimize the efficient acquisition engine that attracts and converts high-intent users, directly enhancing our core business metrics.
You'll be at the forefront of Epidemic Sound's growth, developing the platforms that handle everything from our public pages and referral programs to new in-product upsell experiences. This is a high-impact, data-driven team where you'll see the direct results of your work on the company's revenue. You'll operate in a fast-paced environment, using A/B testing and quick iterations to optimize our user funnels. This role involves significant cross-functional collaboration, working closely not only with other engineering teams (like payments, monetization, and platform) but also with our SEO, commercial, and marketing experts.
Your key responsibilities include:
- Taking ownership of key technical systems, including our public pages, referral program service, and CMS, ensuring their continuous development, maintenance, and observability.
- Actively driving experimentation and A/B testing to improve core metrics like conversion rates and payment success, while also developing the tools to support fast iteration.
- Handling full-stack development tasks (React, TypeScript, Python/Go/Kotlin), with a growing focus on building in-product upsell experiences on the frontend.
- Building and monitoring solutions with SEO and performance top-of-mind, guarding our search ranking and optimizing for LLM:s.
- 6+ years of full-stack experience, including modern frontend (React, TypeScript, HTML, CSS) and backend technologies (Python, Go, and/or Kotlin).
- Proven experience in a growth-engineering environment, specifically with experimentation (A/B testing) and using metrics to drive decisions.
- A collaborative and adaptable mindset, with the ability to work effectively across different functions, disciplines, and product teams.
- Strong communication skills and experience driving technical initiatives from ideation to completion, influencing how your team collaborates and ships code.
- An "empowering initiator" attitude—you excel at taking ownership of projects while actively involving and empowering your peers to foster their growth.
- SEO best practices, web performance optimization, Next.js (or other server-side rendering tools), Tailwind, observability tools (like Prometheus/Grafana), and GCP.
We believe that bringing people together from different backgrounds, experiences and perspectives makes for a healthy workplace, a more successful business and a better world. We value diversity and encourage everyone to come and soundtrack the world with us.
