Sign up with Clera and we'll reach out the moment a role actually fits you — no more spraying applications into the void.
Develop and improve features for an app market intelligence SaaS platform, focusing on SMBs. Tasks include API design, data aggregation, parsing, and optimizing complex database queries.
Requires over 2 years of experience with Go and strong SQL skills in Postgres or ClickHouse. Candidates must be able to pass technical interviews in both Russian and English.
Sensor Tower’s digital intelligence platform provides unparalleled insight into market trends, advertising, competitor’s strategies, and consumer/user audience across mobile, web, and gaming. Sensor Tower’s insights are trusted by more than 2,500 enterprises worldwide across tech, retail/commerce, entertainment/media, gaming, consumer packaged goods, finance, and investment.
At Sensor Tower, we process tens of terabytes of data to power insights used by thousands of customers. 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.
If you enjoy learning, solving problems, and shipping real software that users rely on, we would love to meet you.
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.
Improving and building new features for an app market intelligence SaaS platform focused on the SMBs (AppMagic by Sensor Tower).
Participate in the full development life cycle, including design, implementation, quality polish, and release.
Work on a variety of tasks, such as parsing, data aggregation, API design, refactoring, and performance optimization.
Create and optimize complex database queries for data analysis and modification.
Perform code reviews, and suggest improvements to tools and processes.
We don’t expect you to handle everything from day one. You’ll be supported by teammates, starting with maintenance tasks to get to know the product better, and gradually taking on more ownership as you grow.
Backend stack: Golang, PostgreSQL, ClickHouse, MongoDB, Elasticsearch, RabbitMQ, GitLab, Docker, Kubernetes.
+2 years of experience with Go (if you have lesser years of experience but have meaningful github contributions and other coding samples, this will be taken into consideration).
Strong SQL skills (Postgres/ClickHouse). You know when to rely on an ORM and when to write raw SQL, and you're comfortable writing and debugging complex queries.
Focusing on quality by writing testable code that simplifies debugging and ensures long-term reliability.
Ability to see the product through the user’s eyes and a passion for product excellence.
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.
Experience with CI/CD, docker, k8s as a plus.
Ability to pass technical interview both in Russian & English.
Hands-on, thoughtful use of AI tools in development.
