Job description

About Vantedge AI

Vantedge AI is a YC-backed fintech re-imagining how private-credit, private-equity, and hedge-fund teams turn mountains of deal data into decisions. Our multi-agent workspace ingests everything from bond prospectuses and trustee reports to full data rooms, then delivers structured models, crisp memos, and live dashboards in seconds—end-to-end secure and audit-ready.

Founders

Ravi – 20-year Wall Street credit-investing veteran; former CIO of Eight Capital (acquired by JC Flowers) and Wharton MBA.
Vijay – ex–Goldman Sachs quant engineer; IIT Delhi & IIM Bangalore alumnus, CFA charter holder.

Who You’ll Work With

A fast-moving team split across San Francisco, New York, and Mumbai—alumni of IITs, BITS Pilani, University of Mumbai, and high-growth fintechs. We ship weekly, measure everything, and give every developer true end-to-end ownership.

Why Join Us

Immediate impact: your APIs and infra ship to leading credit funds within days.
Deep domain + cutting-edge AI: build distributed systems powering multi-agent workflows.
Direct founder access: work closely with Ravi and Vijay to shape architecture and culture.

Help us define how AI transforms Wall Street’s backend—one system at a time.

What You’ll Do

Build and scale backend APIs in Node.js / TypeScript (and Python where needed) across REST and GraphQL.
Own distributed architecture across Lambda, ECS Fargate, API Gateway, SQS/SNS, Step Functions, and event-driven pipelines.
Integrate deeply with the AI stack—AWS Bedrock, OpenAI GPT-4o, Google Gemini, Pinecone, Elasticsearch—to support retrieval and agent workflows.
Design secure, multi-tenant systems with IAM, Cognito, KMS, audit logs, and SOC-2–aligned practices.
Optimize performance: caching (Redis), concurrency, P90 latency, cold starts, and throughput.
Add observability with CloudWatch, Grafana, OpenTelemetry, tracing, metrics, and alerts.
Write clean, type-safe, tested code (Jest), automate CI/CD (GitHub Actions), and manage infra via Terraform/CDK.
Collaborate with frontend and ML teams to ship fast, reliable end-to-end features.

You’ll Thrive Here If You Have

2–5 years building production backends in Node.js / TypeScript (Python a plus).
Hands‑on depth with AWS: Lambda, ECS Fargate, API Gateway, DynamoDB, S3, SQS/SNS.
Strong fundamentals in API design, distributed systems, caching, and performance tuning.
Experience with Postgres, Redis, and event-based architectures.
Comfort working with AI/ML APIs, vector DBs, or LLM-driven systems (bonus, not mandatory).
Clear, concise communication and an ownership mindset.
Bonus points for Terraform/CDK, GraphQL, OpenTelemetry, multi‑tenant architectures, or fintech exposure.
