**Posted:** 2026-04-08
> Lead the design of Spark's developer tools, dashboards, and wallet experiences for a Bitcoin L2 payment layer. Build interactive prototypes, marketing assets, and leverage AI tools like Cursor and Claude. Requires 5+ years experience designing for technical audiences with strong craft focus.
## Job Description
## What you'll do

- **Build the product.** Own the design of Spark's developer-facing tools, dashboards, and wallet experiences. Make the complexity of L2 infrastructure, stablecoin settlement, and multi-chain interoperability feel simple and trustworthy.
- **Ship prototypes and demos.** Build functional, high-fidelity prototypes that show partners and prospects what Spark can do, not mockups, but working software you can tap through and share. Think interactive demos, proof-of-concept integrations, scenario walkthroughs.
- **Create marketing and launch assets.** Design and build pages, visuals, and materials that communicate Spark's capabilities to developers, enterprises, and the broader crypto ecosystem. You'll help tell the story of what's possible.
- **Work across Lightspark.** While Spark is your primary focus, you'll contribute to the broader Lightspark product and brand alongside three other designers. Small team means you'll have range.
- **Use AI to move faster.** AI isn't a bullet point here, it's how the team works. You'll use tools like Cursor and Claude to prototype, iterate on UI, and compress the distance between idea and shipped product.

## Who you are

**Minimum**
- 5+ years of experience shipping high-quality digital products at a product-driven company
- Strong visual and interaction design skills, you care about craft and it shows in your portfolio
- Fluent with AI-assisted design and development workflows. You already use tools like Cursor, Claude, Copilot, or similar to accelerate your work.
- Experience designing for technical audiences: developers, platform teams, or infrastructure products
- Self-directed. You can take a loosely defined problem, figure out what needs to exist, and build fast.

**Preferred**
- Experience with crypto, payments, fintech, or developer tools
- Familiarity with Bitcoin, Lightning, stablecoins, or L2 networks — or the curiosity to learn fast
- Comfortable working in or around code (HTML/CSS/JS). Not a requirement — AI handles a lot of the heavy lifting — but it helps.
- A portfolio that includes prototypes, demos, or interactive experiences — not just static screens
- Experience on a small design team where you wore multiple hats (product, brand, marketing, prototyping)
- An eye for motion, interaction, and the small details that make software feel considered
