Overview
Bella&Bona is seeking a Data & CRM Engineer to own and optimize our data infrastructure across HubSpot and SQL, ensuring data consistency, accuracy, and reliability across all systems.

You will be responsible for building and maintaining the pipelines that power our CRM and GTM operations — from integration logic and property mapping to automated data validation. This is a hands-on technical role that combines database management, API integration, and CRM system logic.
Your mission
• Maintain and optimize the integration between HubSpot and SQL, ensuring complete, bidirectional, and error-free data synchronization.
• Develop scripts and API connectors to extract, validate, and update CRM data directly from backend systems (e.g., legacy databases, admin portals).
• Build and maintain data quality checks, alert systems, and validation logic for duplicates, missing values, and incorrect mappings.
• Collaborate with RevOps to translate business requirements into data models and technical workflows. • Implement automated processes for data cleaning, enrichment, and normalization (company, contact, and order-level data).
• Ensure lifecycle data accuracy — all HubSpot stages and properties must reflect real backend behavior.
• Write SQL queries and scripts to audit data integrity, support ad-hoc investigations, and produce clean datasets for RevOps reporting.
• Manage API authentication and versioning, ensuring secure and reliable connections between systems.
• Document all integration endpoints, field mappings, and update logic for internal reference.
Your profile
  • 3–5 years of experience in data engineering, RevOps, or technical CRM operations.
  • Advanced knowledge of SQL (required): capable of writing complex joins, validations, and transformations.
  • Experience coding with APIs (Python or JavaScript preferred) — able to read/write data between systems like HubSpot, SQL, and admin tools.
  • Proven experience working with HubSpot API (CRM v3) — including CRUD operations for Contacts, Companies, Deals, and Custom Objects.
  • Experience setting up and managing Webhooks for real-time data sync between HubSpot and external databases.
  • Strong understanding of HubSpot data architecture, including custom objects, associations, and property logic.
  • Proven track record maintaining data quality and sync accuracy across integrated systems.
  • Detail-oriented mindset with strong documentation discipline.
  • English fluency (written and spoken).
  • Hands-on experience with API rate limiting, pagination, and bulk operations
  • Proficiency with data validation frameworks and testing methodologies
Nice to Have
  • Experience with data transformation tools (Make, Zapier, Hightouch, Stitch, etc.).
  • Familiarity with GDPR and data governance best practices. • Knowledge of PostgreSQL or BigQuery.
  • Experience in FoodTech, SaaS, or high-growth B2B/B2C environments.
Why us?
• Shape the backbone of our data ecosystem — you’ll define how information flows, connects, and drives every business decision at Bella&Bona.
• Own real impact — your work won’t sit in the background; it will directly influence how Marketing, Sales, and Customer Success operate every day.
• Collaborate with leaders who value precision and innovation, not bureaucracy — decisions are made fast, and technical ownership is respected.
• Build for scalability — you’ll help us evolve from a fast-growing startup into a data-driven organization with reliable, automated, and insightful CRM processes.
• Be the reference point for all things HubSpot, SQL, and integrations — the go-to person for transforming complex data into clarity and structure.
