Technical Architect – AI-Powered Career Services Portal (Subscription SaaS)

PAN India - Remote

Employment Type: Contract

Role summary

We’re looking for a hands-on Technical Architect to design and lead the build of a subscription-based career services portal used by about 5,000 paying users each month. The product helps users find jobs and apply faster using automation and AI—such as auto-updating resumes per job description, keyword analysis, drafting recruiter email replies (with user approval controls), creating interview questions with suggested answers, and generating a 30/60/90-day plan based on the JD. You will own the overall architecture and ensure the platform is secure, scalable, reliable, and ready for production.

What you’ll do

• Design the full system architecture across the web app, backend services, databases, background workers, email services, AI services, and external integrations.
• Build the automation foundation that powers the product: job queues and workers, workflow orchestration, scheduling, retries, idempotency, dead-letter queues, and full audit trails.
• Lead the design of AI-driven workflows, including:
• Job description parsing, match scoring, and keyword/skill gap analysis
• Resume tailoring and versioning (v1/v2/v3) with ATS-friendly outputs
• Automated email responder (classify inbound email → draft response → attach the right resume version → user approval or auto-send rules)
• Interview preparation packs (role-based and behavioral questions with suggested answers tied to the user’s real experience)
• JD-based “expected work” outputs (30/60/90 plan and deliverables)
• Own security and privacy end-to-end: OWASP best practices, encryption, secrets management, RBAC, audit logs, and data retention/deletion policies.
• Implement subscription and usage controls: Stripe Billing integration, entitlements, quotas/AI credits, and rate limiting and abuse prevention.
• Set up strong engineering operations: CI/CD pipelines, infrastructure-as-code, monitoring/logging/tracing, alerts, runbooks, and reliability targets (SLOs).
• Work closely with product and engineering teams, review technical designs and pull requests, mentor developers, and drive delivery from build to production.

Must-have technical skills

Backend & architecture (choose one primary stack)

• Node.js (NestJS/Express) or Python (FastAPI) or Java (Spring Boot)
• Strong API design experience (OpenAPI, versioning, pagination, idempotency), access control (RBAC/ABAC), and rate limiting

Data and search

• PostgreSQL (schema design, performance tuning, migrations)
• Redis (caching, distributed locks, rate limiting)
• OpenSearch/Elasticsearch for job search and keyword relevance
• Vector search / RAG (pgvector or similar) for semantic JD-to-resume matching (strongly preferred)

Automation & workflow orchestration

• Queues such as SQS, RabbitMQ, or Kafka
• Workflow orchestration using Temporal, AWS Step Functions, or an equivalent platform
• Background workers and schedulers for batch applications, follow-ups, and retries

AI/LLM engineering (production experience)

• Tool/function calling, structured outputs (schema validation), and prompt/version management
• Safety controls: hallucination prevention, PII redaction/handling, and human approval gates
• Cost controls: caching, batching, quotas/AI credits, and fallback strategies

Email systems

• Transactional email providers: Amazon SES, SendGrid, or Mailgun
• Inbound email parsing and event webhooks (bounces/complaints), plus deliverability setup (SPF/DKIM/DMARC)

Cloud, DevOps, and security

• Docker, CI/CD (GitHub Actions/GitLab CI), and Infrastructure-as-Code (Terraform/CloudFormation)
• Kubernetes (EKS/AKS/GKE) or Serverless platforms (Lambda/Cloud Run)
• Observability using OpenTelemetry with metrics/logs/traces (Datadog/New Relic/Prometheus/Grafana)
• Security fundamentals: OWASP Top 10, secrets management (Secrets Manager/Vault), encryption in transit and at rest

Nice-to-have

• Stripe Billing and webhook-driven subscription lifecycle experience
• Secure document handling (S3/Blob storage, validation/scanning, PDF/DOCX generation)
• Experience building compliant automation systems, anti-abuse controls, and job/ATS integrations through partner APIs or feeds
