And we believe everyone should be able to use it.\nWhen it comes to text and images, giants like OpenAI and Google have already cracked the code. With video, Veo3, Sora and others are closing the gap rapidly. But with its endless languages, dialects, accents, subtle intonations, and speech melodies voice remains a highly complex unsolved frontier.\nThat is exactly why we started Deepslate.\nBacked by top-tier investors from the Tech and AI sectors, as well as a major German VC fund, we are incredibly well-funded and moving fast.\nWe are building the future of communication.\nWe aren't trying to build another standalone platform; instead, we are the intelligence engine powering countless other applications. Whether it's integrated as a module by a CRM provider, plugged into another Voice AI platform, or directly embedded into an enterprise system by our integration partners - our model is everywhere.\nYour Role\nWhile our core engine is API-first, our developers need world-class interfaces to interact with, configure, and integrate our voice models. Your mission is to architect and own the entire front-end ecosystem from developer dashboards and billing portals to real-time interactive voice applications.\nFrom state management and user workflows to raw rendering performance and client-side observability: You are building the face of our AI infrastructure.\nBring Deepslate to Life in the Browser\nYou’ll work on building highly reliable web applications that serve developers and enterprise clients. Your work will directly impact how people perceive and interact with our AI, making a complex technology feel engaging, efficient, and intuitive.\nArchitect & Own: Take complete ownership of designing and building our modern front-end stack from the ground up using TypeScript and React (e.g., Next.js).\n\nFlawless User Experience: Build responsive, accessible UIs capable of handling complex data and real-time interactions without dropping a frame.\n\nPerformance-First Mindset: Write exceptionally clean, consistent code. Advanced state management, optimized bundle sizes, and fast load times.\n\nProduction Ownership: Troubleshoot and resolve live client-side issues, and build the testing systems (unit, integration, E2E) that ensure UI regressions never happen.\n\nElevate Our Engineering Quality to the Next Level:\nTooling & DevEx: Design and build robust internal component libraries and streamline our front-end CI/CD pipelines.\n\nSustainable Architecture: Build highly scalable, modular front-end architectures that allow us to iterate rapidly while keeping maintenance overhead low.\n\nObservability: Implement comprehensive client-side logging and performance monitoring to drastically improve user experience and error tracing.\n\nWhat We’re Looking For: Must-Haves:\nSolid professional experience with TypeScript and React.\n\nReadiness and ability to take complete ownership of a modern Front-End Stack (NextJS or similar frameworks).\n\nA true startup mindset: You are comfortable navigating the chaos of an early-stage codebase (inconsistent structures, missing docs. You name it, you’ll help fix it).\n\nDrive and Vision: You aren't just looking to blindly process Jira tickets. You want to actively shape the product, architect solutions, and take complete ownership of projects.\n\nNice-to-Haves:\nPrevious experience in a fast-paced Startup or DeepTech environment.\n\nExperience with WebSockets, WebRTC, or handling real-time audio streams/data in the browser.\n\nA strong eye for UI/UX design and experience bridging the gap between design tools (e.g., Figma) and code.\n\nFluent German skills (spoken and written).\n\nDeepslate is an equal opportunity employer. We welcome applications from all qualified candidates regardless of gender, nationality, ethnic origin, religion, disability, age, or sexual orientation.","description_format":"text","description_chars":4017,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[{"language":"German","level":"Advanced (C1)","optional":false}]},"benefits":[],"hiring_locations":[{"name":"Germany","iso":"DE","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Speech & Audio AI","AI Agents"],"lifecycle":[{"event":"open","at":"2026-09-12T11:26:50Z"}],"visa":[],"liveness":{"score":5,"band":"cold","label":"Long shot","p_open":1,"p_active":0.171,"p_room":0.28,"age_days":237,"expected_fill_days":13,"reasons":["conf:1","win:tail","crowd:"],"computed_at":"2026-10-30T05:48:23Z"},"pay":{"stated_usd_annual":78576,"is_top_pay":false},"html_url":"https://alion.io/job/deepslate-frontend-engineer-mfd","json_url":"https://alion.io/job/deepslate-frontend-engineer-mfd.json","meta":{"generated_at":"2026-10-30T06:09:56Z","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":8575,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-31T00:00:00Z"}},"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":674304},"rest":"https://alion.io/mcp/rest/get_company?id=674304"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fdeepslate-frontend-engineer-mfd"},{"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%2Fdeepslate-frontend-engineer-mfd"},{"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%2Fdeepslate-frontend-engineer-mfd"},{"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/deepslate-frontend-engineer-mfd\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fdeepslate-frontend-engineer-mfd"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":816501}},{"tool":"search_jobs","arguments":{"company":"deepslate.eu","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":816501},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
