Job Description
Junior Back End Engineer
Sensor Tower
• 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.
Job Requirements
- 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
Benefits
- 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.
