Elixir Engineers at Whatnot are key to enabling rapid product development and real-time features, ensuring our platform scales efficiently alongside our fast-growing business. To achieve our ambitious scaling goals, we are investing in world-class platform infrastructure, balancing speed of innovation with long-term stability.

We foster a collaborative culture, where the platform and product engineering teams work closely together to build resilient, high-performance systems. Our engineering team operates with high autonomy and responsibility, so we need trusted engineers who can translate platform strategy into scalable, maintainable system designs.

What you’ll do

• Develop and optimize Elixir applications for performance, reliability, and scalability.
• Design and implement fault-tolerant, resilient infrastructure to support critical business features.
• Collaborate between infrastructure and product teams to build and enhance user-facing features.
• Improve observability through logging, tracing, and monitoring, ensuring system health.
• Contribute to the long-term technical roadmap, influencing key architectural decisions.

👋 About You

• Bachelor’s degree in Computer Science, a related field, or equivalent work experience.
• 5+ years of software development experience.
• Deep knowledge of the BEAM VM, or the Elixir programming language and Open Telecom Platform.
• Experience building scalable, production-ready applications using Elixir and BEAM.
• Ability to understand business logic code quickly in a larger platform; Python experience preferred.
• Experience in a public cloud environment (AWS, GCP).
