Mid Level Software Engineer – Backend

Jobtailor; Joinville; Presencial; BRL 180 000 - 260 000; Tempo integral

Resumo da oferta

Jobtailor is seeking an experienced backend engineer to design and evolve domain APIs using NestJS/TypeScript within a strict layered architecture.

You will implement event-driven communication, optimize PostgreSQL, leverage Redis caching, and contribute to secure, scalable REST contracts while collaborating with front-end teams and ensuring high test coverage.

Qualificações

• Experience with NestJS and Node.js ecosystem.
• Strong TypeScript and clean-architecture fundamentals (SOLID).
• Deep PostgreSQL knowledge: schema design and indexing.
• Hands-on experience with event-driven architectures (Pub/Sub) and idempotency.
• Familiarity with layered/hexagonal service design and keeping business logic out of controllers.
• Experience designing and consuming REST APIs at scale (versioning, contracts).
• Authentication & authorization basics (JWT, SSO, OAuth).
• Docker and containerized deployments.
• Git and Agile workflows (Scrum/Kanban).
• Experience deploying to Google Cloud (Cloud Run/Cloud SQL/Secret Manager).
• Redis for caching and real-time data.
• Experience in distributed/multi-service (microservices) systems and monorepos.
• Reuse-first mindset: extending shared platform code.

Responsabilidades

• Design and evolve domain APIs in NestJS/TypeScript following layered architecture.
• Build event-driven communication with Pub/Sub using transactional outbox and idempotent consumers.
• Model and optimize PostgreSQL schemas and queries with proper indexing.
• Use Redis for caching and session data with TTL and invalidation.
• Design clean, versioned REST contracts with correct HTTP verbs and responses.
• Implement authentication and authorization (JWT/SSO) via a central gateway.
• Collaborate with front-end/BFF on contract-first API interfaces.
• Write unit and integration tests as a first-class delivery item.
• Participate in code and architecture reviews and document decisions.

Descrição da oferta de emprego

Responsibilities

• Design and evolve domain APIs in NestJS/TypeScript following a strict layered architecture: thin controllers, business logic in the service layer, data access isolated in repositories.
• Build event‑driven communication between services with Pub/Sub, using patterns such as transactional outbox and idempotent consumers to guarantee reliability.
• Model and optimize PostgreSQL schemas and queries—proper types, indexing, and normalization decisions (when a field should really be a related table).
• Use Redis for caching and session data, with deliberate TTL and invalidation.
• Design clean, versioned REST contracts (plural resources, correct HTTP verbs and status codes, standardized JSON response envelopes).
• Implement authentication and authorization (SSO/JWT via a central gateway), always revalidating permissions on the server—never trusting the client.
• Collaborate with front‑end/BFF engineers on typed, contract‑first API interfaces.
• Write unit and integration tests as a first‑class part of delivery.
• Participate in code and architecture reviews, and help make (and document) sound architectural decisions.

Requirements

• Solid experience with NestJS and the Node.js ecosystem.
• Strong TypeScript and object‑oriented / clean‑architecture fundamentals (SOLID, separation of concerns, dependency inversion).
• Deep PostgreSQL knowledge: schema design, indexing, query optimization.
• Hands‑on experience with event‑driven / message‑based architectures (Pub/Sub, queues, or similar) — retries, idempotency, ordering.
• Comfort with layered / hexagonal service design and keeping business logic out of controllers and infrastructure.
• Experience designing and consuming REST APIs at scale (versioning, contracts).
• Authentication & authorization fundamentals (JWT, SSO, OAuth concepts).
• Docker and containerized deployments.
• Git and Agile workflows (Scrum/Kanban).
• Ability to write unit and integration tests to ensure reliability.
• Strongly desired experience deploying to Google Cloud (Cloud Run, Cloud SQL, Pub/Sub, Secret Manager, Cloud Scheduler/Jobs).
• Redis for caching and real‑time data.
• Experience in distributed / multi‑service (microservices) systems and monorepo / shared‑library setups.
• A reuse‑first mindset: extending shared platform code instead of duplicating.
