Lead Full-Stack Engineer

Project Description

The project focuses on building and expanding a translation management tool for websites operating across multiple language regions. The system will enable efficient handling of localized content and automate translation workflows using AI.

At the core of the solution is the integration of the tool with multiple CMS platforms to synchronize content, translations, and metadata across environments.

Our requirements

Core stack & build skills

Expert in TypeScript, React, Node.js; comfortable designing small backend services (auth, webhooks, queueing, secure API calls).
Experience with headless CMS, preferably creating connectors/plugins

- - Sanity plugin development (React tooling, schemas, GROQ).
  - Builder.io extensions (app tabs/editor extensions), plus experience hosting external JS bundles and mediating Admin API via backend.
  - APIs & data: REST/GraphQL, schema discovery, content modeling, webhooks/eventing, write-back flows across CMSs.

Nice-to-haves
- Working knowledge of AEM constraints and deployment paths; comfort navigating vendor tooling.
- Some PHP exposure (useful for pairing with the Drupal freelancer).

Orchestration & leadership

Acts as a counterpart to the client’s engineering manager: turns requirements into technical plans, maintains the integration roadmap, and reports progress/risks clearly.

Frames each connector: defines scope, acceptance criteria, tech stack, and the exact developer profile needed (e.g., “Drupal PHP module dev”).
Sets up parallel workstreams: briefs additional implementers, reviews code, standardizes patterns (auth, error handling, logging, DX), and enforces quality gates.
Owns security & secrets strategy (per-user keys via centralized service), CI/CD, and release/rollback plans.

Scope of responsibilities

Design and implement integrations between the tool and various CMS platforms (via REST/GraphQL APIs, webhooks, write-back flows)
Develop custom plugins and extensions (e.g., Sanity plugins, Builder.io extensions) using React, Node.js, and TypeScript.
Build small backend services for authentication, API mediation, queue processing, and webhook handling.
Define scope, acceptance criteria, and technical requirements for each connector/integration.
Manage and coordinate external contractors (e.g., PHP developers for Drupal, AEM specialists).
Maintain the technical roadmap, report progress and risks.
Design and manage security and secrets strategy (e.g., per-user keys via centralized service).
Set up and maintain CI/CD pipelines, release, and rollback strategies.
Collaborate with the Project Manager on technical solution design and integration architecture decisions.
