Job Description

Posted on: December 2, 2025

We’re opening a Senior Software Engineer position in our Growth Team, a cross-functional group focused on accelerating Product-Led Growth. This is a hands-on engineering role for someone who can build fast, think product-first, and thrive in an experimental environment.

You’ll work closely with engineering, marketing and product, driving growth-focused initiatives directly inside the product experience. Expect rapid iteration, close collaboration, and ownership of experiments end-to-end.

Responsibilities

  • Enable fast experimentation that supports evidence guided decisions. Implement user-facing experiments when needed, ensuring high-quality executions that validate hypotheses quickly.
  • Work directly with product and engineering teams and services across the full platform to design and build scalable product growth features.
  • Contribute to and influence architecture.
  • Own the full lifecycle of growth initiatives: ideation, technical design, implementation, rollout, instrumentation, and iteration based on results.
  • Work with product and marketing team members to shape experiments, ensuring technical feasibility and efficient execution.
  • Maintain strong engineering standards across performance, reliability, and code quality while operating in a fast-moving environment.
  • Improve observability, analytics, and experimentation frameworks to speed up learning cycles.
  • Share knowledge across the team and contribute to a culture of rapid learning and continuous improvement.

Your profile

  • 8+ years of experience in software engineering, with significant experience building and delivering large-scale, high-performance distributed systems.
  • Experience in growth engineering, product engineering, marketplace platforms, or PLG-focused teams is a plus.
  • Experience in Python and its ecosystem. Frontend skills are a strong advantage.
  • Comfortable with DevOps practices, cloud environments (ideally AWS), and monitoring tools, you own your code in production.
  • Deep understanding of performance, reliability, data integrity, and scalable system design.
  • Pragmatic, hypothesis-driven, and comfortable making tradeoffs to move fast while preserving technical quality.
  • Enjoys collaborating with non-engineering partners and incorporating customer and business context into technical decisions.
  • High ownership mindset with a bias toward action and measurable impact.
