Job Title: Full Stack Web Developer

Description

The role of a mid-senior level full stack web developer involves designing and operating between front-end and back-end layers that support our web applications. This includes secure form handling, lead enrichment and routing to customer relationship management/marketing automation systems, content and feature toggles for experimentation, and clean observability for troubleshooting.

This position requires building and maintaining REST/GraphQL APIs for website features: secure form submission, file uploads, gated content, and event endpoints. It also involves implementing lead processing pipelines: validation, deduplication, enrichment (e.g., firmographics), scoring hooks, and routing to CRM/MA (Salesforce/HubSpot).

We are seeking an individual with experience integrating with third-party SaaS (CRM, Marketing Automation, CDP/intent tools) via webhooks/queues with retries and idempotency. The ideal candidate should have a solid understanding of API design, authentication/authorization, rate limiting, and secure data handling.

The successful candidate will be responsible for ensuring data quality and compliance (consent, opt-in, audit logs), plus robust error handling and observability (logs/metrics/traces). They will also support experimentation and personalization-friendly architectures (feature flags, configuration services, edge-friendly APIs) with performance in mind.

Requirements
  • 2–4 years of experience in full-stack development (Node.js/TypeScript/React/SQL) with web-focused services.
  • Solid understanding of API design, authentication/authorization, rate limiting, and secure data handling.
  • Experience integrating with CRM/MA and third-party SaaS via APIs/webhooks; familiarity with retries/idempotency.
  • Practical knowledge of databases (relational and/or NoSQL), data modeling for marketing/growth use cases, and caching.
  • Comfort with logging/monitoring (e.g., OpenTelemetry), debugging in production, and writing clear documentation.
  • Collaborative mindset with Front-end, RevOps, and Growth; ability to translate business requirements into technical solutions.
  • Advanced English Skills.

Benefits

This is a mid-senior level full-time position in Engineering and Information Technology/Software Development.
