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.

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.
