About VisibilityStack

VisibilityStack is a demand capture platform that helps businesses capture the demand for their solution, wherever their audience is searching, whether it's Google Search or AI-Search platforms or LLMs. The platform is powered by AI agents that identify what your audience is asking to look for a solution like yours, engineer content that answers those questions, and structure it so Google and AI systems can easily understand and recommend it in their responses. We also strengthen your online credibility through strategic backlinks and a strong social presence.

Everything is guided by real-time data and analytics. We system continues to analyze what's working, remove what does not, and keep your content working around the clock. The result is simple: the right people can find you, trust you, and reach out when they need what you offer.

The Role

We need a Senior Engineer who ships production code that scales. You'll be the technical anchor—building critical infrastructure, solving complex problems, and mentoring junior developers through code reviews and pair programming.

You'll shape our future in four key ways: writing the code that becomes our foundation, We’re looking for a Next.js Developer (Full-Stack) who can build and ship modern web products end-to-end. You’ll work across frontend, backend, and cloud (AWS) and collaborate closely with product and design to deliver fast, reliable experiences. A strong plus: you have a knack for AI-enabled products—you understand how to integrate LLM features thoughtfully, not just “add a chatbot”. This is about technical leadership through excellence.

What's in it for you:

1. Own mission-critical systems end-to-end — Your code directly generates customer revenue
2. Skip the politics, ship products — No layers of approval, no enterprise bureaucracy
3. Shape product direction — Your technical insights influence product strategy, not just implementation
4. Learn cutting-edge AI in production — Work with LLMs, vector databases, and agent orchestration at scale
5. Shape technical decisions and processes — Your input matters on how we build, not just what
6. Accelerated growth path — As we scale, you choose: become our technical lead or remain a deeply influential IC
7. Direct founder access — Collaborate on product vision, not just execute specs

Location: Janakpuri, Delhi (Hybrid - Maker's Schedule)

Our Work Philosophy:

We follow the Maker's Schedule, not the Manager's Schedule. This means uninterrupted blocks of deep work when you're building, and high-bandwidth collaboration when we're solving problems together.

In Practice:

1. In-office days: Whiteboard architecture sessions, rapid product iterations, deep dives into product strategy, complex debugging that needs three minds on one problem
2. Deep work days: Uninterrupted coding from wherever you work best—home, office, or that coffee shop with perfect noise levels
3. Balance by design: We optimize for both intense collaboration and deep focus

The best technical breakthroughs happen in two modes: intense in-person collaboration where ideas bounce rapidly, and deep solo work where complex problems get solved. We protect both.

Responsibilities

• Build and maintain production-grade web applications using Next.js (App Router preferred), React, and TypeScript.
• Develop full-stack features including APIs, server actions, background jobs, and integrations.
• Architect and implement scalable systems on AWS (deployment, monitoring, security, performance).
• Work with databases (SQL/NoSQL), caching layers, and queues where appropriate.
• Collaborate with product/design to turn requirements into clean UX and shippable increments.
• Own quality through testing, code reviews, CI/CD, observability, and performance tuning.
• Contribute to technical decisions, architecture, and best practices across the team.

What You’ll Bring (Required)

• Strong experience with Next.js + React + TypeScript in real production apps.
• Solid full-stack fundamentals:API design, authentication/authorization
• data modeling and query optimization
• debugging distributed systems issues
• Strong working knowledge of AWS, such as: Lambda, ECS/Fargate, EC2, S3, CloudFront
• RDS/DynamoDB, API Gateway
• IAM, secrets management, VPC basics
• CI/CD and infrastructure practices (Terraform/CDK is a plus)
• Good engineering habits: clean, maintainable code
• testing mindset
• performance and security awareness

AI Product “Knack” (Preferred / Nice to Have)

• Experience integrating AI features using APIs (e.g., OpenAI, Anthropic, Bedrock) including:prompt/version management
• structured outputs / tool calling
• retrieval (RAG) patterns and embeddings (basic familiarity is fine)
• Ability to design AI features with UX and safety in mind:latency expectations, fallbacks, streaming responses
• evaluation/quality loops, guardrails, and logging
• Curiosity about how AI changes workflows and product capabilities.

Tech Stack (Example)

• Next.js, React, TypeScript, Tailwind (or similar)
• Node.js, Postgres/MySQL (and/or DynamoDB)
• AWS (Lambda/ECS/S3/CloudFront/RDS), CI/CD (GitHub Actions, etc.)
• Observability: CloudWatch, Sentry, OpenTelemetry (any equivalent)

What Success Looks Like

• You can take a feature from idea → implementation → deployment with minimal oversight.
• You ship reliable releases and improve system performance and DX over time.
• You help the team build AI-powered features that users actually trust and use.
