Principal Software Engineer

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:

• 2-4 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.
• Multi-tenant SaaS experience, RBAC, audit logs, and security-first design patterns.
• High ownership mindset; comfortable with ambiguity, tight timelines, and strong accountability.
• Strong communication—clear docs, crisp decisions, visible trade-offs.

Nice to Have:

• Practical AI experience (not just demos): LLM integrations, prompt/tooling patterns, evaluation, safety/guardrails RAG/semantic search, embeddings, vector stores, reranking, data pipelines
• Cloud familiarity: AWS/GCP/Azure, containers, basic infra-as-code, observability tooling.
• Experience shipping AI features with measurable quality (latency, accuracy, cost, adoption)
