About this role

ABOUT PHAIDRA

Phaidra builds AI agents for AI factories.

As demand for AI grows, data centers need to get more out of the power and
infrastructure they already have. Power, cooling, and compute are closely
connected, and making them work efficiently is one of the biggest challenges in
scaling AI.

Phaidra builds AI agents that help data center operators understand their
infrastructure, troubleshoot issues, and optimize how their facilities run. Our
agents connect data across IT and OT systems, helping teams find problems faster
and use existing resources more effectively. Operators use Phaidra to optimize
performance, reliability, and efficiency. From helping technicians get to the
root cause of an issue to optimize cooling and power allocation, our work helps
data centers maximize tokens per watt.

Phaidra was founded in 2019 by former Google, DeepMind, and Trane engineers. Our
team brings deep experience in AI, cybersecurity, mission-critical cooling, data
centers, and industrial controls. We believe deploying AI in production demands
deep domain expertise. We work closely with our partners to tackle challenges
around real-world infrastructure at gigawatt-scale.

Our team has a track record of applying AI to the toughest problems. We achieved
superhuman performance with DeepMind’s AlphaGo and cut the energy needed to cool
Google’s data centers by 40%. We know AI deeply, and we know how to apply it in
production for massive impact.

Phaidra can only achieve its mission if we work well together. Our core values
define how we do that: Agency, Velocity, Craft, and Truth. We look for people
who embody these values. They help our team deliver excellence consistently and
build an engaging, supportive culture.

Phaidra is headquartered in the USA, but we are 100% remote with no physical
office. We hire internationally with support from our partner, OysterHR. Our
team is spread across the USA, Canada, the UK, Sweden, Spain, Portugal, the
Netherlands, Singapore, Australia, and India.

WHO YOU ARE 

As a Senior Product Designer, you’ll own end-to-end design across major surfaces
of Phaidra's platform, from early concept to shipped, production-ready UX
working closely with Product and Engineering to turn complex systems into
interfaces people trust.

**We are seeking teammates who are based in the US or Canada (Eastern timezone)

RESPONSIBILITIES

* Own end-to-end design for your product surfaces: discovery, flows,
interaction design, visual polish, and what happens after launch

* Translate customer and internal requirements into detailed process flows,
wireframes, and product designs, accounting for user and product ecosystems,
workflow patterns, and business needs

* Use research, experimentation, analytics, and user feedback to understand
what people need and where the product can improve

* Build working prototypes in Figma and in code, vibecoding with Claude, Cursor
or similar daily to explore and validate ideas quickly, and know where AI
helps and where craft must lead.

* Partner directly with engineering to refine interactions, iterate quickly,
and ship high-quality work

* Simplify complex workflows into interfaces that feel simple and obvious, even
when the underlying logic isn't

* Think in terms of systems, not just screens, and if necessary, use that
mindset to contribute to new patterns or evolving existing ones in Phaidra’s
design system, keeping them consistent and scalable across teams.

* Facilitate design reviews, communicate the reasoning behind your decisions
clearly, and gain alignment with stakeholders

* Mentor others designers, give and take critique, and help raise the bar for
craft across the team

* Care about outcomes, not just output: adoption, usability, and the real-world
impact of what you ship

* Design with accessibility in mind, making sure interfaces work for people
with different abilities and needs

KEY QUALIFICATIONS

* 6-8 years of product design experience, with a portfolio showing strong
visual craft and real business impact

* Figma power user: deep comfort with component systems, auto layout, and
prototyping

* Experience contributing to and evolving a design system

* A high standard for usability and accessibility, with the pixel-level craft
to match

* Experience using or willingness to use AI tools (Claude, Cursor, v0, or
similar) as part of your design workflow, with good judgment on where AI adds
value and where human craft still matters

* Comfortable across the full design stack: UI, interaction design, information
architecture, research, and design strategy

* Experience conducting usability tests and customer research and translating
insight into concrete design decisions

* Strong communicator, able to articulate design rationale and adapt the story
for different stakeholders, from the floor to the boardroom, in an all-remote
setting

* Alignment with Phaidra's values: Agency, Velocity, Craft, and Truth

PREFERRED SKILLS & EXPERIENCE

* Domain experience in data centers, critical infrastructure, industrial, or
energy systems

* Experience working with AI tools

* Experience designing for LLMs or dashboards
