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

7–8 years total engineering experience with deep expertise in Java + Spring Boot and production systems at scale.

Proven tech-lead experience : leading 3–6 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 ≥15–25% 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.
