Job description

Make sure the right data ends up in the right place

At BONANA, we build smart RevOps solutions for ambitious B2B companies. HubSpot forms the core of our clients' tech stack, and you make sure that core is fed with clean, reliable data. We're looking for a pragmatic Data Engineer who's a specialist in integrations and migrations, and who knows exactly how to get data into HubSpot the right way.
What you’ll do

You're the engineer who makes sure systems talk to each other and data is always accurate. No endless architecture sessions, just hands-on building of solutions that work.

• Data Integrations: You build and maintain connections between HubSpot and other systems such as ERPs, financial tools, and other sources. You mainly work with n8n and are also able to build custom solutions via REST and GraphQL APIs.

• Data Migrations: You migrate data from legacy systems to HubSpot. You ensure a clean data structure, proper mapping, and a reliable end result, with no surprises down the line.

• CRM Data Quality: You understand how a CRM works and know how data needs to be modeled to be usable for sales, marketing, and operations. You help think through the right object structure, field choices, and relationships within HubSpot.

• Hands-on Engineering: You write Python and SQL where needed, and have no trouble debugging API calls, building workflows in n8n, or resolving data inconsistencies.

• Collaboration: You work closely with our Solution Engineers and consultants. They translate client needs into a design; you make sure the technical execution is solid.
  

  Do you have the BONANA core values?

  With us, you work on your own growth and the team's (become a true G.O.A.T.)

  • Gamechanger: You're always looking for the smartest and most efficient solution.

  • Ownership: You feel responsible for the end result, from the first design to going live.

  • Ambitious: You keep developing yourself and closely follow the latest trends in data and AI.

  • Togetherness: You love sharing your knowledge with colleagues and work closely together to help clients move forward.

How you work

You're a great fit at BONANA if you have:

• Experience: 3-6 years of experience as a Data Engineer, Integration Developer, or similar role, preferably in a B2B environment.

• HubSpot or CRM: You have experience with HubSpot, or have previously worked with another CRM such as Salesforce or Pipedrive, and know how CRM data should be structured.

• Integrations & Migrations: You have demonstrable experience connecting systems via APIs and migrating data between platforms.

• Tooling: You preferably have experience with n8n. Zapier or Make is fine too, but n8n is our tool of choice. You have a solid command of SQL and Python.

• Pragmatic: You're not looking for an environment with big data warehouses and ML pipelines. You actually enjoy solving concrete, well-defined problems properly.

• Communication: You can clearly explain what you're doing and why, and you're not afraid to flag when something isn't technically feasible or needs a different approach.

What you get

• Growth: The chance to help build an ambitious agency that's making real strides.

• Salary: A competitive salary between €4,000 and €5,500 gross per month, depending on experience.

• Development: Plenty of room for your own initiative, experimenting with new tools, and personal growth.

• Benefits: A solid pension plan, mobility allowance, and all the hardware you need.

• Work culture: An informal, down-to-earth culture where we celebrate results and value humor.
