What we need is someone who has built polished, high-performance B2C products at a startup, knows how to ship fast without cutting corners, and can raise the bar for a growing front-end team.\n\nResponsibilities: \nFront-End Architecture: Define and evolve the front-end stack, patterns, and conventions. Make decisions on state management, component design, performance strategy, and build pipelines. Build and maintain scalable, reusable components and patterns that support multiple products and use cases.\nB2C Product Development: Build responsive, mobile-first web applications that serve thousands of merchants and end users. Obsess over load times, interaction quality, and polish.\nTeam Leadership: Lead and mentor a small team of front-end developers. Run code reviews, establish standards, and create an environment where engineers grow.\nAPI Integration: Work with back-end teams to design and integrate RESTful APIs. Own the contract between front end and back end.\nDesign Collaboration: Partner with product designers to translate Figma/design specs into pixel-perfect, accessible interfaces. Contribute to and maintain a shared design system.\nQuality and Testing: Champion front-end testing culture using Jest, React Testing Library, or Cypress. Ensure critical user flows are covered.\nPerformance: Monitor and optimise Core Web Vitals, bundle sizes, and rendering performance. Set up tooling to catch regressions early.\n\nRequirements: \nB. Tech, B. E., MCA or equivalent.\n6-8 years of hands-on front-end development experience, with at least 2 years in a lead or senior role.\nExperience working at a startup; you thrive in environments where you wear multiple hats, make trade-offs independently, and ship under ambiguity.\nA strong portfolio of B2C products - apps or web experiences used directly by consumers or small business owners.\nYou think in systems, not just screens. You care about reusable components, consistent patterns, and maintainable codebases.\nExcellent communication skills - you can articulate technical trade-offs to engineers, designers, and non-technical stakeholders alike.\nA critical thinker who debugs complex issues methodically and proposes pragmatic solutions.\nYou take pride in mentoring others and building a strong engineering culture.\n\nTech Stack: \nDeep expertise in the first two is non-negotiable; the rest you should be comfortable with or ready to pick up quickly.\nMust-have: Next.js, Tailwind CSS\nCore: React, TypeScript, HTML5, CSS3, JavaScript (ES6+)\nTesting: Jest, React Testing Library, Cypress (or equivalent)\nTooling: Git/GitHub, CI/CD pipelines, Webpack/ Turbopack\nCollaboration: JIRA, Confluence, Agile/Scrum workflows\nNice to have: Familiarity with Figma, analytics/A/B testing platforms, monorepo tooling\nSkills\nCSS, JavaScript, Next.js, React, React.js, Tailwind, TypeScript","description_format":"text","description_chars":2941,"description_truncated":false,"requirements":{"experience_years_min":6,"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":["Recruiting Software & ATS"],"lifecycle":[{"event":"open","at":"2026-10-28T16:35:35Z"}],"visa":[],"liveness":{"score":90,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.903,"p_room":1,"age_days":0,"expected_fill_days":29,"reasons":["seen:0","velocity","win:early"],"computed_at":"2026-10-29T05:49:05Z"},"pay":null,"html_url":"https://alion.io/job/klimb-io-lead-frontend-developer","json_url":"https://alion.io/job/klimb-io-lead-frontend-developer.json","meta":{"generated_at":"2026-10-29T18:14:45Z","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":26978,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-30T00:00:00Z"}},"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":1318},"rest":"https://alion.io/mcp/rest/get_company?id=1318"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fklimb-io-lead-frontend-developer"},{"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%2Fklimb-io-lead-frontend-developer"},{"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%2Fklimb-io-lead-frontend-developer"},{"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/klimb-io-lead-frontend-developer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fklimb-io-lead-frontend-developer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3407842}},{"tool":"search_jobs","arguments":{"company":"klimb.io","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3407842},"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.
