Senior/Staff Product Designer

Sift Stack, Inc.•Marina del Rey, CA

About The Position

We’re looking for a Product Designer to join Sift’s Design team and own core user experiences of Sift’s platform. You’ll perform the user research, design the interactions, components, demonstrate workflows in interactive prototypes that engineers will rely on every day to monitor complex telemetry from advanced hardware systems. This is a hands-on, high-craft role. You’ll work shoulder-to-shoulder with Product Management and Engineering, from early problem definition through to shipped product using our design system as a foundation while pushing it forward. You’re someone who thinks in systems but sweats the details, and who is genuinely excited about what hybrid AI design workflows make possible. We’re looking for designers who are genuinely curious; willing to suit up in a spacecraft cleanroom to observe our users. If that resonates with you, we should talk.

Requirements

6+ years of experience in product design (UI/UX), with a strong portfolio demonstrating interaction design for complex, data-rich applications
Storytelling skill set to help align team members around your vision and communicate the problems you’re solving.
Genuine curiosity about or demonstrated experience with AI-assisted design workflows.
Ability to operate across the full design spectrum: high-level UX flows, interaction logic, and pixel-level UI craft.
Strong cross-functional communication skills; you’re comfortable presenting work, receiving hard feedback, and partnering closely with engineers and PMs
A bias for action in fast-paced, ambiguous environments — you shape problems as much as you solve them
A portfolio is required to be considered for this role. We want to see your process — not just polished final screens. Show us how you think through ambiguous problems, how you work with complex data, and how your design decisions connect to user and business outcomes.
U.S. Person Required: Must be a U.S. citizen, lawful permanent resident, or protected individual such as an asylee or refugee in compliance with ITAR (International Traffic in Arms Regulations) / EAR (Export Administration Regulations) regulations.

Nice To Haves

Experience designing data-dense visualization interfaces — dashboards, monitoring tools, charts, or real-time data displays
Background in or exposure to engineering, aerospace, defense, or advanced hardware industries
Familiarity with telemetry, observability, or infrastructure tooling
You’ve worked at an early-stage startup and know what it means to move fast without sacrificing craft

Responsibilities

Lead user research, including on-site customer visits, to develop deep empathy for how advanced hardware engineers work and what they need.
Design core interactions and workflows across Sift’s platform.
Work closely with Product Management and Engineering throughout the full product development cycle, from problem framing to shipped features.
Leverage and extend our Figma-based design system to build new components and patterns that solve real customer problems and increase engineering velocity.
Embrace hybrid AI design workflows to explore directions quickly, iterate with speed, and deliver high-quality work at startup pace.
