About Ketryx:

Ketryx is an AI software platform that enables healthcare life sciences companies to ship life-saving regulated products in weeks instead of years.

Exploding product complexity is burying companies in compliance paperwork and blocking innovation. Our AI software removes this friction, dissolving the historical tradeoff between innovation and compliance, and enables regulated industries to innovate at the pace of modern software.

Just two years since launch, Ketryx already touches the lives of 25M patients and powers 3 of the world’s top 5 MedTech companies and 25% of the Fortune 500 MedTech market. Backed by Lightspeed Ventures, our founders are the former Head of AI at Amgen and CTO of Wolfram Cloud.

Healthcare and life sciences is just the beginning for us. Automotive, aerospace, energy — if it’s regulated, it’s because society decided it matters. These products move humanity, shape our future, and are safety-critical. Come join us and help build the AI platform to power safe innovation.

Our Information Security team is responsible for ensuring the security of our customers and the safety of our data. As the Manager of Security GRC, you will guide the evolution of our established GRC function. You aren't just maintaining a program; you are maturing our capabilities to ensure that security is a tailwind for our business, transforming complex regulatory requirements into a competitive advantage.

You will be a strategic leader who balances high-standard execution with a focus on Revenue Enablement, ensuring our security posture removes friction from the enterprise sales cycle and reinforces our market position as a trusted partner.

What you'll do

• Take ownership of an established team to elevate our GRC maturity. You will develop and refine our Integrated Management System (IMS) across ISO 27001, 27017, 27018, and SOC 2 Type II.

• Modernize our risk reporting by leveraging quantitative risk management. You will move beyond qualitative "Red/Yellow/Green" charts to provide real-time, data-driven insights and financial risk projections using FAIR principles.

• Serve as a leading voice on our AI Governance Committee. You will guide the secure adoption of AI/LLM features within our product and oversee the governance of AI integration across our internal SaaS ecosystem, aligned with ISO 42001.

• Focus on GRC as a revenue driver. By maturing our compliance and risk functions, you will ensure our security trust posture supports global growth and instills immediate confidence in our largest enterprise customers.

• Partner with Product and Engineering to validate and mature technical controls within cloud environments (e.g. AWS, GCP) and cloud data warehousing environments (e.g. Snowflake). You will ensure that compliance is a seamless part of the CI/CD pipeline and agile software development lifecycle.

• Provide expert guidance on GDPR and CPRA, ensuring our risk management strategies remain resilient in a rapidly changing global privacy landscape.

What you'll bring

• You have 7+ years in Information Security and a track record of maturing established teams. You know how to keep team performance on track while maintaining momentum toward strategic goals.

• You have a deep understanding of AWS security services and Snowflake data governance. You are comfortable challenging and supporting technical teams to innovate and solve strategic challenges.

• You embody a growth mindset and use data and facts to inform priorities. Experience with SAFE Security or similar CRQM platforms is a significant plus.

• A Change Leader: You are comfortable with ambiguity and adapt quickly when priorities change. You encourage experimentation within your team to automate evidence collection and risk discovery.

• A Caring Collaborator: You lead with empathy and inclusion, building diverse teams that support one another. You are a cultural ambassador who can see things from others' viewpoints and reconcile multiple stakeholder views to drive results.

• A Clear Communicator: You bring people along with your vision. You can translate technical risk into business value for executive decision-makers and functional leaders.

Our Leadership Competencies:

We hire leaders who are a Catalyst for Impact, a Coach to their peers, a clear Communicator, an innovative Change Leader, and a Caring Collaborator. In this role, you will be expected to:

• Set high standards and take full ownership of the GRC roadmap.

• Proactively manage the growth of team members through clear feedback and experiential opportunities.

• Engage key decision-makers across business functions to support complex, cross-functional initiatives.

• Navigate organizational dynamics to establish accountability and ensure successful delivery of results.

The Opportunity

If you've worked alongside hardware teams, you know the damage that results from a missed change request or critical context that was never relayed to the right person. Reflow exists to close that gap. We're building the first AI-powered platform purpose-built for hardware product development, one that listens across the tools teams already use, maintains a structured picture of every program, and proactively coordinates across disciplines when things inevitably change.

This is a ground-floor opportunity for a hands-on frontend engineer to shape the user experience of a high-potential product with the support of a parent company leading innovation in engineering and manufacturing.

Who We're Looking For

We're seeking a frontend engineer who cares deeply about building interfaces that are fast, intuitive, and delightful. The ideal candidate has shipped production React applications and has strong opinions on component architecture and design systems. You should already be using AI coding tools like Cursor, Copilot, or Claude to accelerate your work, with excitement about building the product that finally replaces the spreadsheets and status meetings that hardware teams have been stuck with for decades.

This senior engineer will work alongside our engineering team and head of product to build the interfaces through which users manage structured engineering artifacts (requirements, project plans, dependencies), interact with ambient AI agents, and get real-time transparency into project health across disciplines. The role is hands-on - you will be coding daily while contributing to frontend architecture decisions and helping grow the design system as we scale.

What You'll Do

Your day-to-day responsibilities will include:

● Building production-grade React applications with TypeScript

● Developing and maintaining a shared component library

● Building rich interfaces for structured engineering data: requirements with traceability, phase/gate tracking, dependency graphs, task boards with discipline tags, and version-controlled project plans

● Building interfaces for AI agent interactions including streaming chat, proactive coordination alerts, and AI-generated status summaries and deliverables (proposals, SOWs, reports)

● Implementing portfolio-level dashboards for engineering leaders and executives showing cross-project cost, schedule, and risk

● Writing well-tested code with unit and end-to-end tests

● Collaborating with backend engineers on API integration and client SDK usage

● Contributing to frontend architecture decisions, code reviews, and engineering best practices

Technical Requirements

Must Have:

● 5+ years building production web applications, with 3+ years focused on React

● Demonstrated proficiency using AI coding tools (Cursor, Copilot, Claude, etc.) to accelerate development

● Expert-level expertise with React, TypeScript, and modern JavaScript

● Strong experience with component-driven development, design systems, and tools like Storybook

● Proficiency with CSS frameworks (Tailwind CSS preferred) and responsive design

● Experience with modern build tools (Vite, esbuild, or similar)

● Understanding of API integration patterns (REST, OpenAPI, generated clients)

● Ability to balance rapid iteration with maintainable, well-tested code

Highly Valuable:

● Have worked in early-stage 0 to 1 startup environments

● Familiarity with hardware development, engineering workflows, or project management processes

● Experience building UIs for AI/LLM-powered features (streaming responses, chat interfaces, structured AI output)

● Familiarity with headless component libraries (Base UI, Radix, Headless UI)

● Background in data visualization or dashboard-heavy applications

● Understanding of authentication/authorization patterns (OIDC, JWT)

● Experience with end-to-end testing frameworks (Playwright, Cypress)

● Background in B2B SaaS platforms, project management tools, or technical collaboration products
