Senior Software Design Lead, IDEO San Francisco
In a nutshell:

IDEO San Francisco is in search of a Senior Software Design Lead who will architect the human and technical systems behind the digital products and AI experiences we design, build prototypes that behave like real production software, and be the technical voice client CTOs trust. You'll pick up design at IDEO along the way.
Why is this role important for IDEO's work?

Software design makes the biggest impact by turning a product vision into a technical architecture a client's engineers can actually build, and by testing ideas in working code rather than slides.. Their skillset is critical to our business because the work has evolved from designing interfaces to designing systems: how people, software, and AI agents behave together. We count on them to understand data models, APIs and agentic infrastructure from first principles. and speak credibly on technical choices with executives and engineering leaders.
Once here you will:

• Work with product designers, product strategists and design researchers on 8-12+ week digital product engagements that may span from product vision and strategy to full end-to-end build. You will play a key role in turning human insights into technical architecture: data, APIs, integrations and the agentic layer.
• Build early prototypes with real data, real models and real integrations, so we learn quickly and lower the risk of big bets.
• Advise client executives and engineering teams on tech stack choices, build-vs-buy, evaluating APIs and LLMs, and feasibility.
• Design how agents and systems behave on a human's behalf, including guardrails, failure states and how the system stays legible to both people and machines.
• Raise the craft bar inside IDEO. Create reusable starter kits and toolkits so teams stop building from scratch, and coach designers who prototype in code.
• Help shape proposals and scope technical work in business development.

Some previous projects to check out:

Straight Arrow News: a redesigned news app and website with features like See All Sides, Sources and Media Landscape views. App page views grew 1,170% and active users 700%. This role would design the content and data model underneath and prototype with real feeds.

Gates Foundation - Last Mile Money: human-centered design for 100+ digital financial products serving 34M underserved users. This role would work on architecture for low-connectivity settings and evaluate partner platforms and APIs.

Jack Technology - Aitu: AI-enabled industrial sewing machines and a humanoid robot, designed around how they work with factory workers. This role would work on system behavior: how the AI signals what it's doing and how humans stay in control.
Relevant experience and mindset:
Must-haves:

• 8-10+ years as a software engineer shipping production software, ideally at growth-stage or established tech companies where speed and scale both mattered. You've taken products from concept to launch.
• 2-3+ years as an engineering lead or solutions architect: scoping, estimating and planning projects, and making architecture decisions others build on. You think at a systems level.
• Deep software fundamentals, including systems design, data modeling, APIs, and tradeoffs around performance, security and scale, plus fluency in a modern stack (e.g., TypeScript, React, Python, Node; AWS, GCP, Azure).
• Hands-on building with LLMs (tool use, agents, retrieval, evals) and advanced prototyping. You turn concepts into working software quickly, using real data and integrations, with quality that holds up beyond vibe coding.
• A track record of working closely with product, design and data, plus curiosity about people and a desire to learn how the craft of software intersects with product and design. You use prototypes as a way to think, not just to deliver.
• Strong communication and storytelling: architecture diagrams, system maps and presentations that make technical recommendations clear and persuasive to executives and engineering leaders.

Nice-to-haves:

• Comfort with Figma, design systems and front-end craft
• Client-facing or consulting experience, or taking part in UX research
• Experience with hardware or connected devices (Arduino, IoT)

Pop quiz, Hot Shot:

• A client's CEO wants "an AI agent in the app by Q2." What's your first question for the CEO?
• What's a piece of software that's beautifully built under the hood, not just on the surface? What makes it good?

Application requirements and instructions:

Résumé or LinkedIn + Cover Letter

GitHub or two to three work samples (code, architecture docs, side projects or technical writing)

A short response of about 300 words: "Tell us about a technical decision you made that shaped how people experienced a product. What were the tradeoffs, and what would you do differently today?"
