The platform is used by enterprises and high-growth startups to become the default tools recommended by software agents.\nLightsage focuses on agent experience and measurable impact on developer and product adoption, with more information available at lightsage.com. The team also created DevToolArena.com, a public benchmark that ranks developer tools across areas such as authentication, inference, and voice using Claude Code and Codex.\nRole Description\nAs the Founding Design Engineer at Lightsage, you will shape how our product looks, feels, and works. You will work directly with the founders, engineers, and customers to design and build intuitive, beautiful, and performant interfaces that make complex technical workflows simple.\nThis is a hybrid design and engineering role. You won't just hand off designs to engineers. You'll take ideas from initial concepts and prototypes all the way to production, owning both the user experience and the frontend implementation.\nYour day-to-day work will include designing and building product interfaces, creating interactive prototypes, developing reusable components, establishing a scalable design system, and continuously refining the product experience. You'll work across agent analytics, data visualizations, onboarding, dashboards, and customer-facing recommendations, translating complex technical data into clear and actionable experiences.\nYou'll also play a foundational role in establishing Lightsage's design and frontend standards, making decisions about interaction patterns, component architecture, performance, and visual consistency as the product scales.\nWe're looking for someone with strong design instincts and exceptional frontend engineering skills. You should care equally about how a product looks and how it works, with the ability to move fluidly between Figma and code.\nPrevious experience in the agent or AI market is not required. Experience building polished, data-intensive B2B products, developer tools, or analytics platforms is particularly relevant.\nQualifications\n2-3+ years of experience in frontend engineering, design engineering, or a similar role, ideally at an early-stage or high-growth software company.\n\nStrong proficiency in React, TypeScript, HTML, CSS, and modern frontend development frameworks such as Next.js.\n\nExceptional visual design and interaction design skills, with a strong eye for typography, spacing, layout, motion, and attention to detail.\n\nExperience designing and implementing polished, responsive, and performant user interfaces from concept through production.\n\nAbility to translate Figma designs into high-quality code and independently design interfaces when no mockups exist.\n\nExperience building reusable components, design systems, and scalable frontend architectures.\n\nFamiliarity with data visualization, dashboards, developer tools, or complex technical workflows.\n\nStrong understanding of frontend performance, accessibility, responsive design, and cross-browser compatibility.\n\nAbility to prototype rapidly, iterate based on customer feedback, and balance design quality with engineering constraints.\n\nHigh ownership, dependable execution, and comfort operating in an early-stage startup with minimal structure.\n\nPlease include a link to your portfolio, GitHub, or examples of products and interfaces you've designed and built. We especially value shipped work that demonstrates both your design sensibility and engineering ability.\nThis is a full-time, on-site role based in San Francisco, CA, with significant ownership and direct influence over Lightsage's product experience, design system, and frontend architecture.","description_format":"text","description_chars":3887,"description_truncated":false,"requirements":{"experience_years_min":2,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Artificial Intelligence","AI Agents","Developer Tools"],"lifecycle":[{"event":"open","at":"2026-10-08T02:50:35Z"}],"visa":[],"liveness":{"score":37,"band":"fade","label":"Fading","p_open":1,"p_active":0.668,"p_room":0.55,"age_days":20,"expected_fill_days":16,"reasons":["conf:1","win:tail","comp:junior"],"computed_at":"2026-10-10T05:45:15Z"},"pay":null,"html_url":"https://alion.io/job/lightsage-founding-design-engineer-2","json_url":"https://alion.io/job/lightsage-founding-design-engineer-2.json","meta":{"generated_at":"2026-10-11T23:14:45Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":14006,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-12T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":3863147},"rest":"https://alion.io/mcp/rest/get_company?id=3863147"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Flightsage-founding-design-engineer-2"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Flightsage-founding-design-engineer-2"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Flightsage-founding-design-engineer-2"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/lightsage-founding-design-engineer-2\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Flightsage-founding-design-engineer-2"}]}
