As a Senior Design Engineer, you will build the critical interface where scientists interact with AI reasoning. Balancing 80% frontend and 20% backend, you’ll design in code to make complex agentic workflows legible and trustworthy. You will own the entire UX lifecycle, from initial prototypes to production-grade, high-performance streaming interfaces.
Senior Design Engineer at Perceptic Technologies
Perceptic Technologies is building the AI operating system for drug discovery, and they're looking for a Senior Design Engineer to bridge the gap between high-stakes science and agentic AI. Founded by ex-Palantir operators and backed by $12M from Accel, this seed-stage team already has paid deployments with top-20 pharma companies. If you're a frontend-heavy engineer who sweats the details of typography and streaming AI interactions, this is your chance to build the interfaces that scientists use to make life-changing discoveries. Join a high-intensity environment where your craft directly impacts human health.

Role overview
Perceptic is an AI-first operating system for drug development and biopharma that connects evidence, data, decisions, and workflows across the entire drug lifecycle, from early research and asset scouting through scientific evaluation, clinical trial design, and clinical data analysis. It provides a shared intelligence layer that unifies fragmented pharmaceutical R&D tools and data sources so that insights compound over time and every decision is made with full scientific and operational context. The platform is infrastructure- and model-agnostic and is already deployed in large pharmaceutical organizations, where its modular AI workers and products such as Scout, PercepticOS, and Atlas support asset triage, hypothesis testing, and clinical data synthesis, mirroring how scientists think and work while enabling scalable, end-to-end AI-driven drug discovery and development.
What you will do
- Design and ship production-grade UIs that make AI scientific reasoning legible by surfacing provenance, citations, and confidence.
- Build and maintain a scalable design system and component library that ensures high-quality interaction patterns across the entire platform.
- Rapidly prototype and iterate on live agent runs, handling partial states and tool calls to ensure AI transparency for scientists.
Who this is a fit for
- At least 4 years of professional experience with a frontend focus in React/TypeScript, modern CSS, and performance optimization.
- Fluent in both Figma and code, with a strong design sensibility for typography, layout, and complex interaction design.
- Proven track record shipping polished AI or product UIs in high-bar environments like FAANG or top AI labs.
Why this role is remarkable
- Work at the intersection of AI and human health, building the intelligence layer that powers drug discovery for top-20 pharma companies.
- Join an elite team of ex-Palantir operators with $12M in funding from Accel and a high-intensity, high-ownership culture.
- Bridge the gap between design and engineering, owning the craft of streaming AI and interaction problems most teams haven’t solved.
