Description
About the Role
We're looking for a Senior Backend Engineer to build and scale the GenAI Lens backend platform. This is a production-focused role centered on MongoDB data design and performance, scalable/durable data ingestion and processing pipelines, and operating high-throughput systems with strong observability and reliability.
You'll also help build and evolve our API layer (GraphQL and JSON-RPC). Experience with GraphQL is a strong plus, but the core focus is data systems and platform engineering. You should be comfortable working in a product that leverages modern AI technologies (embeddings, vector search, LLM integrations) and understand the practical standards that come with them-evaluation, guardrails, observability, and cost controls. What You'll Work On Maintain and improve our data pipelines to keep data flowing reliably from ingestion to delivery Scalable, durable data ingestion and processing pipelines (event-driven, fault-tolerant workflows; retries, idempotency, backfills, and DLQs) Own data quality by implementing monitoring, alerting, and validation Design MongoDB schemas and query/index strategies for scale (aggregation pipelines, Atlas Search/vector search where relevant) JSON-RPC data layer service that powers GraphQL (designing/maintaining RPC methods, scaling throughput/latency, and evolving contracts safely) Support AI-adjacent platform needs (embedding generation workflows, provider abstractions, prompt/model metadata, evaluation hooks) Responsibilities: Own backend services end-to-end, from design and implementation through deployment and production support Deliver scalable GraphQL resolvers with performance-aware patterns (batching, caching, pagination) Build and evolve the JSON-RPC data access layer for GraphQL, including method design, backward compatibility, and performance tuning. Own MongoDB performance: modeling, indexing, aggregation pipelines, and measurable latency/throughput targets Build reliable serverless/event-driven components (idempotency, retries, DLQs, backpressure, rate limiting) Improve reliability and operational readiness (SLO-minded engineering, incident response hygiene, runbooks) Partner closely with frontend, product, and UX to enable features cleanly and safely Drive code quality via testing, reviews, and CI/CD improvements Mentor engineers and influence engineering standards across the team Required Skills & Experience Experience building and maintaining backend services in production Strong experience with GraphQL APIs (schema design, resolver patterns, authorization, performance) Strong experience with MongoDB (data modeling, indexing, aggregation pipelines; Atlas Search and Vector Search, sharding experience is a plus) Strong proficiency with Node.js and JavaScript / TypeScript Strong proficiency with Python (services, jobs, data processing, or tooling) Experience building on AWS, preferably serverless/event-driven architectures (Lambda, SQS/SNS/EventBridge, S3) Experience working with high-traffic or business-critical systems Solid understanding of performance optimization techniques (caching, async processing, data access patterns) Experience with Terraform for production infrastructure (IAM, networking, secrets, repeatable environments) Experience with testing frameworks and pragmatic test strategy (unit, integration, contract) Familiarity with CI/CD pipelines (GitHub Actions preferred; alternatives acceptable) Experience debugging, monitoring, and operating production systems Comfortable working in a distributed team environment Strong operational skills: logging, metrics, tracing, dashboards/alerts, and production support practices Infrastructure & Platform Experience Cloud experience, preferably AWS, including: Lambda SQS / SNS / EventBridge / Kafka S3 CloudWatch API Gateway (where applicable) Experience with Infrastructure as Code, preferably Terraform Experience with private networking patterns (VPC, security groups, PrivateLink/VPC endpoints) is a plus Exposure to containerized workloads (EKS/Kubernetes) is a plus, even if the core architecture is serverless-first Collaboration & Others Prior experience leading projects, features, or technical initiatives Ability to influence architecture and design decisions Strong ownership mindset and ability to identify and execute improvements independently AI & Developer Productivity Familiarity with embeddings and vector search concepts, and the tradeoffs they introduce (latency, cost, relevance) Experience integrating with LLM/embedding providers via clean abstractions (timeouts, retries, fallbacks, rate limits) Awareness of AI industry standards/practices: prompt/version management, evaluation/regression checks, basic guardrails, and auditability Hands-on experience using AI tools to improve development workflows and code quality (e.g., Copilot, Claude Code, OpenAI-based tools) Ability to articulate how AI has improved development speed, quality, testing, or maintainability Nice to Have Experience building high-throughput services (e.g., millions of requests/minute class systems) and tuning concurrency/connection pools Experience designing "saved filter" or "materialized view" style performance optimizations for analytics/trends workloads Experience with multi-region data and compliance-minded architectures Experience refactoring legacy systems or consolidating services for efficiency and cost savings Why Join This Team Help build a modern backend platform where quality and scalability are non-negotiable, enabling a high-impact product for the company with visible outcomes and real customer adoption. Work with cutting-edge technologies and modern AI tooling (embeddings, vector search, LLM providers, evaluation/guardrails) while staying grounded in strong backend engineering practices. Supportive, collaborative team culture-ideas are heard, discussed openly, and improved together as a group What We Offer:
Enjoy comprehensive paid time off that allows you to have an enhanced work-life balance Excellent medical, dental, and vision options 401(k) matching, life insurance, commuter benefits, and parental leave plans Complimentary CalmApp subscription for you and your loved ones, because mental wellness matters. Energetic work environment with a hybrid work style, providing the balance you need.
