Senior Software Development Engineer

Role Description

This is a remote position.

We are looking for a Software Development Engineer III (SDE 3) to design and own systems that span teams and shape the foundation of our Agentic AI platform for enterprise sales.

As an SDE 3, you will:

• Design and own systems that span a team or multiple teams.
• Apply SOLID and design patterns with judgment.
• Drive trade-off, reliability, and operational conversations unprompted.
• Remain deeply hands-on in code.
• Act as a technical multiplier for the engineers around you.

Key Responsibilities

• Architect Systems: Design multi-service systems with clear ownership boundaries, making strong choices on storage, partitioning, caching, sync vs. async paths, and API contracts.
• Raise the LLD Bar: Handle larger, less-bounded problems, model cleanly, justify pattern choices, and design plugin/registry-style extensibility.
• Own Hands-On Delivery: Write production-quality code for core platform components and lead complex features end-to-end.
• Drive Trade-offs & Reliability: Lead deep trade-off analysis, define SLOs, identify failure modes, and own observability and capacity planning.
• Shape the AI Platform: Contribute to multi-agent orchestration, reasoning pipelines, memory systems, tool-use frameworks, and evaluation harnesses.
• Technical Leadership: Set engineering standards, lead design reviews, contribute to hiring, and mentor mid- and junior engineers.
• Evaluate Emerging Tech: Stay ahead of the AI engineering landscape and assess frameworks and tools.

Qualifications

• B.Tech / M.Tech in Computer Science from a premier institute (IIT, BITS, NIT, or equivalent).
• 6–10 years of hands-on software engineering experience, with a track record of delivering production systems at scale.
• Deep low-level and system design skill; able to own architecture discussions and design reviews for large, ambiguous problems.
• Strong command of distributed systems, microservices, and cloud-native architectures (AWS).
• Prior experience in a technical lead or staff-engineer capacity, including design ownership and mentorship.
• Applies SOLID and design patterns with judgment.
• Proficiency with vector databases (Pinecone, Weaviate, FAISS, or similar) and embedding pipelines for semantic search and retrieval.

Good to Have

• Experience with LLMs and Agentic systems in production, including fine-tuning or RLHF for domain-specific models.
• Foundation in LLMOps: model evaluation, observability, guardrails, A/B testing, and drift detection.
• Familiarity with coding agents such as Claude, Cursor, GitHub Copilot, or custom agent tooling.
• Experience in a B2B SaaS or enterprise product environment, particularly sales-tech or GTM tooling.

Benefits

• Own meaningful features and services in a category-defining enterprise AI Product.
• Work alongside a world-class team — engineers from Amazon, McKinsey, IIT, Stanford and top-tier investors including Peak XV and Stellaris.
• Real autonomy over how you build.
