• Strong understanding of databases, application architecture, API design, and software design fundamentals.
• Experience writing clean, testable, maintainable code and operating production systems responsibly.
• Hands-on experience shipping applied AI or LLM-powered features, or strong experience building production software with a clear path into applied AI work.
• Strong product intuition and ability to make thoughtful tradeoffs between speed, complexity, scalability, and user experience.

• Excellent communication and collaboration skills in a cross-functional environment.

   

Preferred Qualifications

• Experience building AI-powered product features in production.
• Familiarity with LLM application patterns such as retrieval, structured outputs, semantic search, and evaluation.
• Experience with document intelligence, OCR, extraction systems, or knowledge ingestion pipelines.
• Experience with vector search, hybrid retrieval, reranking, or search relevance optimization.
• Experience with workflow automation, event-driven systems, or background job orchestration.
• Experience building software in compliance-conscious or high-trust environments such as education, healthcare, or fintech.

• Startup experience or comfort operating in ambiguous, rapidly evolving product environments.

   

What Success Looks Like

In this role, success means you:

• ship high-quality product features across the stack that users rely on every day
• improve core workflows through thoughtful software design and strong engineering execution
• build AI capabilities that are practical, measurable, and trusted by users
• contribute to a platform that is scalable, maintainable, and adaptable as the company grows

Let’s talk. Your next big adventure might just start here.

The Full-stack Web Developer at VyOS Networks is the end-to-end owner of the company's primary web presence at vyos.io. The role is about taking full responsibility for a production Next.js / Vercel / DatoCMS platform: keeping it fast and reliable, shipping new sections and interactive features, evolving the deployment pipeline, and operating inside an AI-native engineering workflow where coding agents (Claude Code, Cursor, or equivalent) are a primary tool for day-to-day development. This is a senior, hands-on role. You will be the person the rest of the company turns to when something needs to ship, get faster, or get rebuilt.

 

Responsibilities
 

• Own, maintain, and evolve vyos.io on Next.js, Vercel, and DatoCMS — from bug fixes and content model changes to net-new sections, interactive components, and performance refactors.
• Design and operate the three-tier deployment pipeline (development → staging → production) — including GitHub Actions workflows, branch protection and merge strategies, promotion gates, and fast-rollback automation using Vercel promote and DatoCMS environment restore.
• Own the testing stack end-to-end: Vitest for unit tests, Playwright for end-to-end coverage, visual regression testing, and flaky-test detection across scheduled runs.
• Model and optimize content in DatoCMS — schema design, GraphQL queries, environment lifecycle (fork / promote / backup), real-time preview and stega overlays, and content workflows that scale across marketing and product pages.
• Operate the marketing and analytics instrumentation layer — server-side GTM (sGTM) pipelines into GA4, LinkedIn CAPI and Reddit CAPI, HubSpot Forms consolidation and security, Cookiebot consent with auto-blocking, and Vercel edge headers for geo-aware rendering.
• Drive continuous web performance improvement — Core Web Vitals (LCP, CLS, INP), image pipelines, preconnects, font loading, bundle analysis, and a CSS-first approach to responsive layout that minimizes client-side JavaScript.
• Own SEO and Generative Engine Optimization (GEO) — JSON-LD / schema.org structured data, sitemap automation, llms.txt, and explicit AI crawler policy (GPTBot, ClaudeBot, PerplexityBot) in robots.txt.
• Work inside an AI-native development workflow — author and maintain CLAUDE.md, write specifications and implementation plans that coding agents can execute end-to-end, and use Claude Code (or an equivalent agent) as a first-class collaborator on production work.
• Harden the platform — Content Security Policy, secure postMessage with origin validation, environment-variable hygiene, and type-safe data flow from DatoCMS through the Next.js app in TypeScript.
• Keep CLAUDE.md and the Confluence WD space (Deployment Pipeline, Merge Workflow Guide, DatoCMS Environments, Architecture Overview) synchronized as the system evolves.
• Collaborate with designers, content creators, marketing, and product teams to turn business goals into shippable, measurable digital experiences.
• Stay current with web technologies, frameworks, and agentic development practices, and continuously raise the quality bar for architecture, tooling, and developer experience.

Requirements
 

Skills
 

• Strong proficiency in Next.js, React, and modern TypeScript — including SSG, SSR, ISR, and API route / middleware patterns.
• Deep hands-on Vercel experience — deployments, environments, promote workflows, edge middleware, edge geo headers (e.g. x-vercel-ip-country), and preview URL hygiene.
• Proficiency with DatoCMS — schema and content modeling, GraphQL, environments and promotion via the DatoCMS CLI, real-time/preview, stega fields, and integration patterns.
• Strong CI/CD skill set with GitHub Actions — including multi-tier branch strategies, branch protection and merge strategies, promotion gates, and rollback automation.
• Solid testing discipline — Vitest and Playwright, with a proven ability to stabilize and debug flaky suites.
• Marketing-instrumentation fluency — GTM, server-side GTM (sGTM), GA4, CAPI integrations (LinkedIn, Reddit, Meta), HubSpot Forms, and consent management (Cookiebot or similar).
• Web performance engineering — Core Web Vitals, LCP/CLS/INP, image optimization, preconnects, font strategy, and bundle analysis.
• Modern styling craft — CSS Modules, SASS, BEM, CSS Grid, custom properties; comfort driving a CSS-first migration that reduces JS-driven responsive logic.
• SEO and Generative Engine Optimization — JSON-LD, schema.org, sitemaps, robots directives, llms.txt, and content discoverability for LLM-based search.
• Security fundamentals for production web — Content Security Policy, safe cross-origin messaging, secret and environment-variable handling.
• AI-assisted development fluency (required). Daily use of coding agents (Claude Code, Cursor, or equivalent), comfort authoring and maintaining agent configuration files such as CLAUDE.md, and the ability to decompose work into specs and implementation plans that an agent can execute reliably. Exposure to agentic workflow patterns (tool use, MCP connectors, skill-style prompt artifacts) is a strong plus.
• Familiarity with modern frontend tooling (npm/Yarn, ESLint, Prettier) and effective collaboration with designers and content creators on UX/UI.

Experience
 

• 5+ years of professional web development experience, with at least 2 years in a senior or lead role.
• Proven track record of owning (not just contributing to) a production Next.js site — including the pipeline, release quality, and on-call-style response to issues.
• Experience designing and operating multi-stage CI/CD pipelines with promotion gates and rollback paths.
• Demonstrated production experience with DatoCMS or a comparable headless CMS where you have designed schemas, modeled content, and driven environment promotion.
• Experience using coding agents productively in a real production codebase — not just experimenting on side projects.
• Prior experience working with open-source projects, developer communities, or technical audiences is a strong plus.
