About Us

Pendulum empowers companies and governments to uncover, understand, and act on current and potential risks and opportunities contained within narratives. We are building a powerful, multi-medium, always-on narrative and community intelligence platform for our customers, while tackling one of society’s biggest problems - combating harmful mis- and disinformation. We are deeply inspired by our mission, motivated by solving hard technical problems, and obsessed with our customers.

Fulfilling our mission demands bringing together a team with a broad range of backgrounds and experiences. Diverse teams are the strongest teams because their plurality of experience enriches and expands the solution space and enriches decision-making. Diversity and inclusion are therefore core to our values and at the forefront of our hiring philosophy and day-to-day operations.

About the role

We are currently seeking a Senior Full Stack Software Developer who can help drive the efforts to develop our future web portal and agentic capabilities. As part of this team, you will work as a tech leader and subject matter expert to lead the development of scalable and robust end-user experiences. This will involve leveraging a highly differentiated, large-scale dataset and utilizing the latest developments in AI to generate value for users from this dataset.

What you'll do

  • Complex web application engineering: To build these interfaces, we need to solve the meta-problem of how to architect our software to unlock the value of our data across multiple domains, our web portal, and agentic experiences.
  • Ship commercial solutions: Our users have a huge job to do, at a massive scale. So, we need to build tremendous, powerful software that just works.
  • ML and big data in real life: Data and ML are at the core of what we do, and we are operationalizing them so that risk & intel, communications, and marketing teams at large companies and organizations can unlock their power. Doing so requires versatile, yet opinionated products - which require versatile, but opinionated engineers.

What you've done

  • Strong Industry Experience: Shown a steady upward career progression in the art of Software Engineering.
  • Complex Architectures: Design, implement, and maintain platforms, engines, or frameworks that others consume. Deliver APIs consumed by modern web applications with an understanding of the complexities and nuances of microservices and databases.
  • Cloud Experience: Leverage AWS at scale (Lambda, ECS, S3, Step Functions, DynamoDB, Bedrock, etc.) to orchestrate high-volume data ingestion, transformation, and AI/ML-driven enrichment workflows.
  • Modern Framework Expertise: Leverage React, Vue, Angular, or a similar framework to build complex interactive UIs.
  • Modern Backend Expertise: Build backend services and systems with languages like Python, Rust, or Go, and understand the complexities and nuances of CRUD, Graph API, and microservices.
  • CS Fundamentals: Earned at least a Bachelor’s or Master’s Degree in Computer Science, Computer Engineering, or equivalent.
  • Collaborate closely with product and sales teams to translate complex business needs into intuitive, performant tools that uncover insights from video, audio, and image-centric platforms.
  • Provide technical leadership and mentorship to a small but growing engineering team, setting coding standards, guiding architectural decisions, and fostering a culture of collaboration and innovation.

What we offer

  • Grow as a professional by working with emerging technologies in a high-demand industry segment.
  • Drive company direction at a company that encourages input from all levels to help shape our trajectory.
  • Experience working at a technology company in which the mission focus is on tackling one of society’s greatest challenges.
  • Learn from industry and government experts who value initiative and encourage innovation.
  • Enjoy the flexibility to work remotely, unlimited PTO, company (and two personal-choice) holidays
  • Receive excellent benefits, including 100% employer-paid employee health premiums (50% for dependents), 401(k), and FSA.
