Descripción de la vacante

LMK Recruiting Solutions is seeking a Frontend Engineer to own the operator interface for a robotics-driven prescription system. You will translate design prototypes into robust React apps and set frontend standards across product interfaces.

The role offers Senior or Staff levels, a hybrid Bay Area work arrangement (3 days on-site), and close collaboration with product design and hardware teams to deliver reliable, scalable UX.

Formación

• End-to-end ownership of critical, high-availability product surfaces in production.
• Advanced TypeScript with strict compiler configurations.
• Modern React with state management over real-time WebSockets.
• Design collaboration to convert prototypes into production-grade software.
• State machines for complex application flows.

Responsabilidades

• Own the operator interface for queues, replenishment, diagnostics, admin, and sign-in.
• Translate interactive designs into robust React apps with pixel-perfect fidelity.
• Maintain touch-first interaction standards and a multi-layer alert system.
• Ensure TypeScript contracts are kept in sync with Rust-based models via WebSockets.
• Design scalable frontend standards extending to cloud dashboards and mobile controls.

Location: Bay Area, CA (Hybrid – 3 days/week on-site)

Compensation: $163K-213K

About Our Client

Our client builds intelligent robotics engineered to automate prescription dispensing. Their flagship machine takes stock bottles of medication and autonomously produces accurately counted, labeled vials, freeing pharmacists and technicians from repetitive manual tasks so they can focus on patient care. Designed to operate right behind the pharmacy counter, their system blends physical robotics with intuitive software.

About the Role

As a Frontend Engineer on the team, you will take full ownership of the primary interface used to operate the machine, a large, touch-only screen built for busy pharmacy technicians working in high-throughput environments. Moving forward, you will also architect and define the frontend standards for every subsequent product interface across the company, including cloud management dashboards and next-generation systems.

This position is open at both the Senior and Staff levels:

• Senior Level: You own the operator screen surface end-to-end.
• Staff Level: You establish the overarching frontend standards, design system practices, and engineering workflows that other engineers build against across teams.

What You’ll Own

• The Operator Interface: Build and maintain the core touch interface covering prescription queues, medication and consumable replenishment, machine diagnostics, system administration, and secure technician sign-in.
• Design-to-Production Fidelity: Partner closely with Product Designers to translate interactive design prototypes into robust React applications with pixel-perfect fidelity.
• Touch-First Principles: Maintain strict touch interaction standards—ensuring appropriate touch target sizes (48px+ minimum), high-contrast readability at a glance, event-driven screen advances, and safeguards against accidental inputs on high-stakes actions.
• Interruption & Notification Architecture: Implement a structured three-tier alert model (ambient status updates, calls for attention, and blocking dialogs) to keep technicians informed without creating cognitive fatigue.
• Type-Safe Systems Integration: Interface with machine-level software via a strict TypeScript contract generated directly from Rust source models over WebSockets, ensuring absolute state sync and reliability.
• Scalable Ecosystem: Architect scalable standards that will extend to cloud operations dashboards, mobile controls, and future hardware interfaces.

What Success Looks Like in the First 90 Days

• First 30 Days: Onboard into the code base, merge initial UI enhancements, and gain deep familiarity with the prescription queue, replenishment workflows, and alert models alongside our product design team.
• First 60 Days: Take full ownership of design updates, refine the end-to-end testing suite for real-world technician workflows, and finalize the three-layer interruption framework.
• First 90 Days: Ensure full production readiness and security compliance for the primary operator interface, solidify frontend engineering guidelines for the organization, and roadmap the architecture for the upcoming cloud operations dashboard.

What We’re Looking For

Must-Have Qualifications

• End-to-End Ownership: Proven experience owning critical, high-availability product surfaces end-to-end in production environments.
• Advanced TypeScript: Deep expertise with strict compiler configurations, writing type-safe abstractions that make invalid application states impossible to express.
• Modern React & State Management: Proficient with React 19 and state architecture over real-time WebSockets. Comfort building screens where domain state is driven reliably from the backend/hardware.
• Design Collaboration: Strong track record of converting living prototypes into high-performance software while maintaining active alignment with design partners.
• State Machines: Comfort reasoning about complex application flows using explicit states and transitions.
• Design Systems: Experience building or maintaining design systems/standards adopted by multiple engineering teams.
• Regulatory / Healthcare: Familiarity with accessibility standards (WCAG 2.1 AA) or regulated domain requirements (healthcare, industrial automation, robotics).

Why Join Us?

• Tangible Impact: Your software directly controls physical robotics operating in real-world pharmacy environments.
• High-Trust Culture: Work with a small, elite engineering team with zero bureaucracy and high operational autonomy.
• Hybrid Work Model: Collaborate in person 3 days a week at our Bay Area headquarters, where you can work directly with the physical hardware and robotics engineering team.
