Junior Software Engineer (Data Platform)

ABOUT THIS ROLE

As a Junior Software Engineer on our Data Platform team, you'll work on the operational and technical systems that keep Wonderflow's global data collection running smoothly.

You’ll start by owning specific, high-impact areas like AWS account operations and day-to-day platform support. As you grow, you’ll expand into core scraping infrastructure work, write production code, and gradually own larger features alongside your team. This is a hands‑on role where you’ll learn fast, take ownership, and grow into a senior technical position.

You will be introduced to:

• Operating and maintaining production data collection systems
• Building operational tooling and automation that reduces manual work
• Writing production Node.js code that handles real‑world data volumes
• Collaborating closely with senior engineers through code review and pair programming
• Debugging complex issues in live systems and learning from failures
• Agile development practices and shipping code to production
• Understanding web scraping challenges and how to solve them at scale

ABOUT THE TEAM

Working at Wonderflow means working as a team with values that embody collaboration, perseverance and success.

Our Data Platform team is a tight‑knit group of engineers dedicated to building the infrastructure that powers Wonderflow's core data collection. We operate in an environment where you ship code early, get feedback quickly, and grow alongside experienced engineers who genuinely care about helping you develop. If you’re curious, eager to learn, and ready to take real ownership of production systems, you’ll thrive here.
