This platform aggregates and harmonizes complex data streams from social media and third-party services, surfacing key performance indicators that drive real-world business impact.

With a fresh codebase (just a bit over one year old), there’s significant room for architectural influence, innovation, and technical ownership. If you're passionate about solving intricate problems, working with cutting-edge web tech, and turning raw data into actionable intelligence, this is for you.

Tech Stack: Node.js, Typescript, Redis, React, Jotai, Apache ECharts, and business logic with Custom-built deduplication and reach and frequency modeling

As a Senior Fullstack Engineer, You Will:

  • Design and implement new backend features to power analytics at scale.
  • Create intuitive and performant user interfaces to visualize data clearly and effectively.
  • Contribute to a math- and logic-heavy business logic layer underpinning our data model.
  • Collaborate directly with stakeholders to shape the product roadmap and feature priorities.
  • Operate as a member of a cross-functional, autonomous team that owns its decisions and outcomes.

What We’re Looking For:

  • Problem Solver & System Thinker: You excel at tackling complexity—whether it’s system architecture, data modeling, or performance tuning.
  • Fullstack Proficiency: You’ve built and shipped robust, high-performance web applications and know how to balance front- and backend concerns.
  • Analytical Mindset: You think deeply about how things work and take a rigorous approach to decision-making. Bonus if you’ve worked with statistical models or have experience in data-driven domains.
  • Fast Learner: You thrive in fast-paced, dynamic environments and are always looking to grow, ask the right questions, and expand your impact.
  • Strong Communicator: You’re comfortable talking to both engineers and business stakeholders, helping bridge the gap between technology and value.

What We Offer You:

  • Inclusive Culture: Join a diverse team of over 750 Smartlies from 60+ nationalities across 24 locations in 13 countries. We foster a culture built on trust and open feedback.
