Full-Stack Developer (Java Spring Boot) | Tech Lead (7–8 Years)

About the role

AdGrid is hiring a Full-Stack Developer cum Tech Lead who pairs cloud optimization & computing expertise with a hands-on developer profile. You will architect, build, and operate secure, scalable, and cost-efficient systems; lead engineers; and independently drive complex, cross-functional projects end-to-end.

What you'll do

• Own architecture & delivery: Translate business goals into scalable designs; write high-quality code; lead planning, estimates, and execution across services and frontends.
• Backend expertise (primary): Java 17+, Spring Boot/Spring Cloud, REST/gRPC APIs, async/event-driven patterns, caching, resilience, and observability.
• Frontend leadership: Modern SPA (React/Next.js preferred); component standards, performance budgets, accessibility, and DX tooling.
• Cloud optimization & computing: Design and operate on AWS/GCP/Azure (AWS preferred); right-size compute/storage/networking; optimize cost/performance; automate with IaC.
• Data & messaging : Model relational schemas (PostgreSQL/MySQL), tune queries/indices; use Redis; build streaming pipelines with Kafka (topics, partitions, DLQ, schema registry).
• Reliability & security: Define SLAs/SLOs; instrument SLIs; implement OWASP controls, secure secrets, encryption in transit/at rest; drive incident response and postmortems.
• CI/CD & platform: Own pipelines (GitHub Actions/Jenkins/GitLab CI), containerization (Docker), orchestration (Kubernetes/EKS), blue/green & canary, feature flags.
• Leadership & management: Mentor engineers, set code/architecture standards, conduct reviews, manage stakeholders, and create clear status/risks/decisions comms.
• Quality mindset: Enforce unit/integration/contract/load tests (JUnit 5, Testcontainers, WireMock/Pact, k6/JMeter) and release readiness checklists.
• FinOps practices: Track and reduce infra spend per user/request; implement autoscaling/TTL/lifecycle policies; ensure cost visibility.

Must-have Qualifications

• 78 years total engineering experience with deep expertise in Java + Spring Boot and production systems at scale.
• Proven tech-lead experience: leading 36 engineers, owning multi-service deliveries, and coordinating cross-functional stakeholders.
• Strong cloud skills (AWS preferred): VPC, IAM, ALB/NLB, EC2/EKS, RDS, S3, CloudFront, WAF, KMS/Secrets; IaC (Terraform/Pulumi).
• Proficiency in React/Next.js (or equivalent), TypeScript/JavaScript, bundlers, and frontend performance tooling.
• Solid with PostgreSQL/MySQL, Redis, and Kafka; understanding of eventual consistency and idempotency. Security fundamentals (OAuth2/OIDC, JWT, TLS/mTLS, input validation, least privilege IAM) and privacy-by-design instincts.
• Excellent communication, documentation, and stakeholder management.

Nice to have

• Spring WebFlux/Reactor, Resilience4j, GraphQL;
• Multi-region design, DR strategy (RPO/RTO), chaos testing;
• Observability stack: Prometheus/Grafana, ELK/EFK, OpenTelemetry;
• DevSecOps: SonarQube, Snyk/OWASP Dependency-Check, SBOM;
• Experience in fintech/payments, consumer tech, or other low-latency domains.

Success in 3-6 months

• Ship a complex, multi-service project on time, meeting SLOs with actionable dashboards and runbooks.
• Reduce infra cost per request/user by 1525% while improving latency/throughput.
• Establish team-wide engineering standards (lint/test/CI gates) and lift change failure rate and MTTR .
• Mentor team to consistently deliver with predictable velocity and high code quality.

Our stack (indicative)

• Java 17+, Spring Boot/Cloud/Data/Security
• React/Next.js, TypeScript
• REST/gRPC PostgreSQL, Redis
• Kafka (+Schema Registry/Avro) Docker, Kubernetes (EKS)
• AWS (VPC, IAM, ALB/NLB, RDS, S3, CloudFront, WAF, KMS/Secrets)
• Terraform GitHub Actions/Jenkins
• Prometheus/Grafana, ELK/EFK, OpenTelemetry
• SonarQube, Snyk.
