Job description

Job Location BUCHAREST OFFICE Job Description The Full Stack Software Engineer designs, develops, and operates cloud-based web applications, APIs, and services on GCP that power our Key Opinion Leader (KOL) / influencer marketing platform across the end-to-end campaign lifecycle. The role supports the Social Digital Products space. Key Responsibilities Build and ship full-stack features end-to-end, from the Next.js UI through FastAPI microservices to Cloud Spanner / BigQuery data stores. Develop and maintain the Next.js (App Router) front-end (TypeScript, React 18+, Tailwind CSS) following the Backend-for-Frontend (BFF) pattern, with clear separation between server and client components. Develop and operate Python 3.11 / FastAPI microservices using the service–repository pattern, Pydantic v2 schemas, SQLAlchemy 2.0+, and dependency injection, exposing REST and GraphQL APIs. Integrate GenAI / LLM capabilities into the platform — using Vertex AI (Gemini), OpenAI / Anthropic, and LangChain / LangGraph via P&G's governed GenAI gateway. Build and operate GCP services (Cloud Run, Cloud Workflows, Cloud Build, Pub/Sub, Secret Manager, Cloud Logging) and contribute to the evolution of the platform toward reusable, self-serve patterns. Integrate with BigQuery and Cloud Spanner for transactional and analytical workloads, applying parameterized queries, partitioning, and cost-aware design; support embedded Looker / LookML reporting. Maintain and improve integrations with social platforms, third-party influencer marketplaces, web-scraping / content-extraction pipelines, and internal P&G systems. Develop and extend Terraform modules for GCP project and landing-zone resources, contributing to self-serve provisioning and policy guardrails. Embed quality and security into CI/CD: unit and integration tests (pytest, jest), E2E tests (Playwright), SonarQube, Snyk, and gitleaks. Partner with product managers, business analysts, architects, and QA to ensure technical solutions are fit for use and aligned with architecture blueprints. Identify, design, and implement performance, reliability, and cost-reduction opportunities, and uphold coding standards and best practices so services and components stay efficient, secure, and reusable. Job Qualifications Bachelor's degree in Computer Science or a related field. Experience in full-stack software engineering, web application development, or a related field. Proficiency with modern web architectures and microservice design patterns. Hands-on experience with TypeScript, React 18+, and Next.js App Router (server/client components, route handlers, BFF pattern). Hands-on experience with Python 3.11+ and FastAPI, including Pydantic, SQLAlchemy, and async patterns. Working knowledge of GCP (Cloud Run, Cloud Workflows, BigQuery, Cloud Spanner, IAM, Secret Manager) and Terraform. Experience integrating (or a strong interest in integrating) GenAI / LLM services — e.g. Vertex AI / Gemini, OpenAI, Anthropic, LangChain / LangGraph — into production applications. Working knowledge of Docker and containerized local development. Strong TypeScript, Python, and SQL skills. Experience writing automated tests (pytest, jest, Playwright) and integrating quality and security tooling (SonarQube, Snyk, gitleaks) into CI/CD pipelines. Familiarity with REST and GraphQL API design, OpenAPI/Swagger, and conventional commits.
