About the company:

At Xenspire Technologies Pvt. Ltd., we are building People-First AI products—AI that augments human decision-making, reduces cognitive load, and earns trust through transparency, control, and reliability.

As a Lead Engineer in the Founding Engineering Team, youʼll help set the technical direction and build the core systems that everything else will run on—product architecture, engineering standards, and AI-first capabilities embedded into real workflows. This is a challenging environment: short feedback loops, meaningful ownership, and problems that donʼt come with a playbook.

If you like shipping fast, thinking deeply, and building systems that scale from day one, youʼll fit right in.

What Youʼll Do:

• Build and own core systems (web + backend + data) from scratch—designed to scale.
• Develop People-First AI capabilities: copilots, semantic search, automated workflows, and decision support—designed with guardrails, explainability, and human-in-the-loop controls.
• Drive architecture decisions: APIs, database design, eventing, caching, security basics, observability, and performance.
• Convert ambiguous business needs into clean product experiences with strong engineering discipline.
• Establish engineering standards: code quality, reviews, CI/CD, testing strategy, release readiness.
• Mentor engineers through example—this is a hands-on role, not a coordination role.
• Partner closely with founders/product/design; make trade-offs and ship outcomes, not just output.

What Weʼre Looking For:

• 5–8 years building production-grade software, ideally in product companies or high-growth startups.
• Strong expertise in Backend: Python/Java, APIs, scalability patterns Databases: PostgreSQL/MySQL + one NoSQL/search system (Elastic/OpenSearch/Vector DB is a plus)
• Proven experience building platforms/products from zero 1, then stabilizing for scale.
• Practical AI experience (not just demos): LLM integrations, prompt/tooling patterns, evaluation, safety/guardrails RAG/semantic search, embeddings, vector stores, reranking, data pipelines
• High ownership mindset; comfortable with ambiguity, tight timelines, and strong accountability.
• Strong communication—clear docs, crisp decisions, visible trade-offs.
• Experience working on SAAS Products or SAAS platforms

Nice to Have:

• Multi-tenant SaaS experience, RBAC, audit logs, and security-first design patterns.
• Cloud familiarity: AWS/GCP/Azure, containers, basic infra-as-code, observability tooling.
• Experience shipping AI features with measurable quality (latency, accuracy, cost, adoption)

Mission

Own architecture across web + backend, ship reliably, and establish patterns the team can scale on.

Responsibilities

• Lead system architecture for Next.js (web) and FastAPI (backend); own code quality, reviews, and release cadence.
• Build and maintain the web app (marketing, auth, dashboard) and a shared TS SDK (@revilo/contracts, @revilo/sdk).
• Integrate Stripe, Maps, analytics; enforce accessibility and performance baselines.
• Define CI/CD (GitHub Actions), containerization (Docker), env/promotions (staging → prod).
• Partner with Mobile and AI engineers on API/tool schemas and developer experience.

Requirements

• 6–10+ years; expert TypeScript, strong Python.
• Next.js (App Router), TanStack Query, shadcn/ui; FastAPI, Postgres, pydantic/SQLModel.
• Auth (OTP/JWT/OAuth), payments, caching, pagination, API versioning.
• Practical CI/CD and observability (logs/metrics/traces).

Nice-to-haves

• OpenAPI typegen (Zod), feature flags, background jobs/queues, Vercel/EAS.

Key Outcomes (ongoing)

• Stable architecture with typed contracts; <2% crash/error on web, p95 API latency in budget, reliable weekly releases.

EXPERTISE AND QUALIFICATIONS

• 14+ years of experience in Software Engineering with at least 6+ years as a Lead Enterprise Architect preferably in a software product company
• High technical credibility - ability to lead technical brainstorming, take decisions and push for the best solution to a problem
• Experience in architecting Microservices based E2E Enterprise Applications
• Experience in UI technologies such as Angular, Node.js or Fullstack technology is desirable
• Experience with NoSQL technologies (MongoDB, Neo4j etc.)
