AI Innovation at Dataminr

Working at Dataminr you’ll have the opportunity to tackle the most exciting trends in AI to power a revolutionary product that uncovers critical events around the world as they unfold.

Regenerative AI: our AI technology, ReGenAI, automatically regenerates real-time Live Event Briefs as events unfold. Learn more.

Agentic AI: we recently launched our Agentic AI capability, what we’re calling our Intel Agents, that autonomously generates critical context for our clients on real-time events, threats, and risks. Learn more.

Multimodal AI: our platform detects events from many different types of data (images, video, sensor data, audio, and text in over 150 languages).

The opportunity

• Own high-impact features from discovery and technical design through implementation, rollout and post-release success measurement.

• Collaborate closely with backend teams to evolve API contracts, caching and data-fetching strategies for resilient, scalable UX.

• Contribute to our frontend platform; design system, component library and tooling and improve developer velocity and product quality.

• Reduce complexity and delivery risk: make pragmatic refactors, address technical debt, and implement guardrails through best practices.

• Collaborate with design and product to clarify legacy constraints, de-risk scope, and ship upgrades iteratively without big-bang rewrites.

At Dataminr, we value you for who you are. We encourage you to apply for this role, even if you don't meet every qualification. Our candidates are reviewed on the basis of their skill and potential to succeed.

• 4+ years of hands-on experience building production React apps with modern patterns (hooks, context, suspense, concurrent features).

• Strong state management experience (TanStack Query, Zustand) with clear trade-off reasoning.

• Experience creating and maintaining internal component libraries or design systems with strong typing.

• Strong REST fundamentals and practical GraphQL experience (queries, mutations, caching, fragments).

• Testing: unit (Jest/Vitest), component/integration (RTL), and E2E (Playwright/Cypress) with good coverage and testing pyramid discipline.

• Excellent problem-solving, collaborative, and technical communication skills to drive feature delivery in a fast-paced environment.
