Role
Who you are
- You don’t need to know everything on day one. We value potential, curiosity, and a strong foundation
- Preferred: Knowledge of Ruby on Rails and the broader Ruby ecosystem is a large plus. Alternatively, demonstrated proficiency in Python or similar languages, with a willingness to cross-train in Ruby, is acceptable
- Nice-to-have: Experience with Clickhouse or other OLAP databases; MongoDB or other document stores; Sidekiq or other asynchronous task runners
- Technical Foundation: A strong grasp of algorithms, RESTful systems, and API design. Experience with data analysis and data pipelining is ideal
- Github/Portfolio: A portfolio of meaningful Github contributions, open-source work, or interesting personal projects that demonstrate you can build working software
- Curiosity & Drive: A proactive approach to digging into sources yourself rather than relying on second-hand information, and an eagerness to understand why a project is valuable before you start coding
- Interest in backend systems and working with data
- Eagerness to learn and ask questions
- Strong communication and collaboration skills
- If you enjoy learning, solving problems, and shipping real software that users rely on, we would love to meet you
What the job involves
- We’re looking for curious, motivated early-career engineers who want to grow their skills while helping us build fast, reliable systems that make data easy to access and understand
- You’ll work closely with experienced engineers, contribute to meaningful features from day one, and learn how large-scale systems are designed, built, and optimized in production
- We have a strong track record of leveling up talented juniors quickly, and this role offers a rare opportunity to pair closely with senior leadership
- As a junior engineer, you’ll be supported by mentors and teammates while you:
- Contribute to features across the full development lifecycle
- Help build APIs and backend services that power customer-facing products
- Learn how to work with large datasets and high-performance databases
- Improve code quality through testing, refactoring, and code reviews
- Pair-program and collaborate with teammates to solve problems together
- Gradually take on more ownership as you grow
- Our Engineering Culture:
- We believe that "Simplicity is a prerequisite for reliability." We are looking for engineers who align with our core values:
- Simplicity: We avoid over-engineering. We prefer the tools we already have and the most straightforward solutions over "shiny new toys."
- Quality: We write code that is a pleasure to read because we know code is written once but read many times. We don't cut corners, and we polish to a high level before shipping
- Extreme Ownership: We don't just do the minimum. We expect you to understand the "why" behind your work and own the ultimate goal of fixing problems at their root cause, avoiding temporary band-aids
- Prioritization: We focus relentlessly on what is important, not just what is urgent
- What You'll Get:
- Mentorship from senior engineers
- Real ownership of features (not just small tasks)
- Exposure to large-scale production systems
- Collaborative culture
- Opportunities to grow and learn new things
