About Optivus

Optivus builds pragmatic, production-grade AI products and solutions. We move fast, value ownership, and ship polished, on-brand work.


Role

Own and ship an end-to-end web application—from scoping and architecture to deployment and post-launch iteration. You’ll work primarily in Next.js across the full stack, use AI coding tools (Cursor, Claude Code, etc.) to accelerate delivery, and collaborate with a small team that moves fast.


What you’ll do


  • Take a product brief from zero → v1: scope, estimate, implement, test, deploy, and monitor.
  • Build frontends with Next.js (App Router), React 18, TypeScript, Tailwind/shadcn/ui.
  • Implement server routes/APIs, integrate databases (e.g., Postgres/Mongo via Prisma/ORM), and wire up auth (Clerk/Auth.js) and RBAC.
  • Own CI/CD, basic infra (Vercel/Render/AWS), and observability (logs, metrics, error tracking).
  • Use AI tools to speed up coding, tests, refactors, and documentation—responsibly and securely.
  • Write clean, well-typed code with thoughtful tests (unit/e2e) and maintainable abstractions.
  • Demo progress weekly; iterate based on user and stakeholder feedback.


Must-have skills


  • Next.js full-stack development with hands-on delivery of at least one complete project (portfolio/GitHub).
  • Ability to own a project end-to-end: scoping, architecture, implementation, testing, deployment, and iteration.
  • Proactive, self-starter mindset; bias to action and clarity in communication.
  • AI-assisted development: practical experience using Cursor, Claude Code, GitHub Copilot, or similar in day-to-day work.
  • Solid fundamentals: modern React patterns, TypeScript, RESTful APIs, SQL/NoSQL data modeling, Git, debugging, and performance basics.


Good-to-have (AI & platform)


  • Experience building AI apps (even small projects): OpenAI/Anthropic APIs, prompt design, RAG, embeddings/vector DBs (Pinecone/pgvector/Weaviate), LangChain/LlamaIndex.
  • Realtime features (WebSockets), background jobs/queues, caching (Redis), and file processing (PDF/Docx).
  • Security and privacy basics: authN/authZ, OWASP, key management, secrets hygiene.
  • Cloud/devops exposure: Vercel/Render/AWS, Docker, basic networking, CI pipelines.
  • Testing: Jest/Playwright, component testing, contract tests.


Who you are


  • A

    self-starter

    who takes ownership end-to-end and thrives with minimal hand-holding.
  • Organized and detail-obsessed; you keep files, versions, and trackers tidy.
  • Comfortable working in a fast-paced startup with shifting priorities—and still shipping high-quality work.


How to apply


Send your resume/LinkedIn, GitHub/portfolio, and one project you owned end-to-end (brief problem → approach → stack → link/screenshot → what you’d improve next) to advik@optivustechnologies.com and udayan@optivustechnologies.com with subject “Full-Stack Intern”
