It should enable it. We're a venture backed category-defining SaaS company headquartered in Denver. We've raised $161 million from investors including Craft Ventures, Valor Equity Partners, and Marc Benioff.\nOur culture runs on four values: customer love, inspire excellence, always be curious, and act like an owner. That means no ego, no politics, and real ownership over your work. If you want to build something that matters for an industry that's ready for change, we'd love to talk.\nOverview\nInsurance powers almost everything, and yet the systems behind it are still held together with spreadsheets and manual processes. AgentSync is fixing that. We build modern infrastructure for carriers, agencies, and MGAs that makes compliance automatic and growth possible.\nIn this role you'll own the experience layer of the AgentSync app and carry features end to end, from the React experience our customers touch through to the Go and Java services that power it. We hire product-minded engineers who think like owners - people who care as much about the customer and the craft of the experience as the code behind it. Our teams run lean, with a high engineer-to-PM ratio and no dedicated designer, which means the engineers closest to the work are the ones defining what great looks like. We move fast, we build with intention, and we expect everyone to bring their full capability to the work - including knowing when and how to use AI to do it better.\nWe're looking for a Senior Full Stack Engineer who is primarily frontend but genuinely full stack. You'll spend most of your time in the new AgentSync App, which we're building from the ground up in our TypeScript and React monorepo. You'll own the quality and architecture of that experience, and carry your work into our Go backend-for-frontend and services when a feature needs it rather than handing it off. You'll help shape the path forward for our frontend architecture and design system.\nWhat You’ll Do\nBuild high-quality, accessible, performant features in React and TypeScript across multiple product areas of the new AgentSync App\nOwn features end to end: the React experience, the API it depends on, and the service changes behind it, including UX, without waiting for a designer to hand you a spec\nEvolve our frontend monorepo, shared packages, build tooling, and the boundaries between apps and help shape the path forward for our frontend architecture\nBuild and extend a shared component library and design system for consistent UX across product areas\nWork in our Go backend-for-frontend and services when a feature calls for it, shaping the API responses and generated types the UI depends on\nWork in an AI-native development process: use Claude to turn product requirements into well-scoped stories, write and review code, and generate tests also help refine the workflows, prompts, and standards that make it work for the whole team\nUse AI design tools - Claude Design where it makes sense - to move from idea to working UI faster\nIdentify opportunities to embed intelligent, AI-assisted experiences into the product\nTake vague problems from Product and turn them into a scoped, sequenced plan, written clearly enough that teammates or AI agents can carry it out, and surface risks and tradeoffs early\nRaise the quality bar through clean, well-tested code, focused pull requests, high-leverage code reviews, and mentorship that works by example rather than gatekeeping\nWhat You’ll Bring\n5+ years building and shipping production, mobile-responsive web applications\nHands-on experience with AI-assisted development, using tools like Claude to generate stories, write and review code, and produce tests with a point of view on where they help and where they don't. Experience on a team where AI agents build from well-written specs is a big plus\nDeep expertise in React and TypeScript, plus modern frontend tooling, state management, and testing (experience with React Query, MUI, Vite, Vitest, or Playwright is a plus)\nStrong web fundamentals - HTML, CSS, accessibility, responsive design, and performance\nA strong design and UX sensibility and be comfortable owning the experience without a dedicated designer\nExperience building or contributing to shared component libraries and design systems\nExperience working in and evolving a frontend monorepo (e.g. Turborepo, Nx, or Yarn workspaces), with a point of view on keeping shared packages and app boundaries healthy\nWorking backend experience in Go or Java (Go preferred), with a solid understanding of APIs, OpenAPI-generated clients, relational data, and how the full system fits together\nFamiliarity with OAuth/OIDC sign-in flows, feature flags, and frontend observability is a plus\nA reputation as a strong reviewer and mentor who raises the technical bar across a team without managing them\nClear communicator with a strong ownership mentality. You take a half-formed problem and come back with a plan, align engineering and product around it, and surface risks and tradeoffs early\nFamiliarity with AWS is beneficial\nA scrappy, gritty, roll-up-your-sleeves mentality - you thrive with ambiguity and ownership\nLocation\nOur ideal candidate will live within 25 miles of our office in Denver. Other states we're able to consider candidates in CA, CO, GA, IL, KS, MA, MI, NY, OR, TN, TX, UT, and WA.\nTotal Compensation\nThe following represents AgentSync’s reasonable estimate of the range of possible compensation for this role.\n$160K-$185K base salary\nAnnual company bonus program\nEquity in the form of stock options\nHealth Benefits\nMedical - Multiple Cigna plans to choose from, with up to 80% employer paid premiums for you and your dependents\nDental - Multiple Cigna plans with up to 80% employer paid premiums for you and your dependents\nVision - 80% paid premium plan for you and your dependents\nEmployee Assistance Plan, Life & AD&D Insurance\nFinancial Benefits\n401(k) retirement savings plan\nHSA employer contributions\nOther Benefits\nFlexible PTO\n12 paid holidays per year\n12 weeks parental leave w/generous return to work stipend\nCandidates: AgentSync Recruiting & Talent teams will only communicate with you using @ agentsync.io email addresses. When you receive communication from AgentSync, check the email address domain to ensure you're connected with our team (and not a scammer!).\nWe are not able to consider candidates who require a work visa now or in the future.\nE-Verify:AgentSync participates in the federal E-Verify program. As required, we will verify the identity and employment eligibility of all newly hired employees through E-Verify.","description_format":"text","description_chars":6669,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Equity","Parental leave","Retirement plans","Stock options"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["RegTech, AML & Compliance","Insurance Brokers & Agencies"],"lifecycle":[{"event":"open","at":"2026-11-04T06:04:16Z"}],"visa":[{"country":"US","licensed_sponsor":true,"evidence":"H-1B filings in 12 months: 3","filings_12m":3,"filings_prev_12m":1,"green_card_filings_12m":0,"median_offered_wage_usd":232500,"route":null,"cap_exempt":false,"checked_at":"2026-10-29T16:27:21+00:00","sources":["US Department of Labor: LCA disclosure data (H-1B, H-1B1, E-3)","US Department of Labor: PERM disclosure data (green cards)"],"filings_for_role_12m":2}],"liveness":{"score":86,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.86,"p_room":1,"age_days":0,"expected_fill_days":35,"reasons":["conf:0","win:early"],"computed_at":"2026-11-04T06:34:25Z"},"pay":{"stated_usd_annual":185000,"is_top_pay":true},"html_url":"https://alion.io/job/agentsync-senior-frontendfull-stack-engineer","json_url":"https://alion.io/job/agentsync-senior-frontendfull-stack-engineer.json","meta":{"generated_at":"2026-11-05T04:30:09Z","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":5575,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-06T00:00:00Z"}},"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":670277},"rest":"https://alion.io/mcp/rest/get_company?id=670277"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fagentsync-senior-frontendfull-stack-engineer"},{"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%2Fagentsync-senior-frontendfull-stack-engineer"},{"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%2Fagentsync-senior-frontendfull-stack-engineer"},{"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/agentsync-senior-frontendfull-stack-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fagentsync-senior-frontendfull-stack-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3726883}},{"tool":"search_jobs","arguments":{"company":"agentsync.io","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3726883},"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.
