Job description

Your responsibilities:

  • Support the design and implementation of a platform currently being developed by the team, working closely with its EM to define priorities and next steps.

  • Contribute to the build-out of features and integrations as scoped, adapting to the platform’s evolving needs and roadmap.

  • Translate technical direction into working code, flagging risks, blockers, or open questions early.

  • Document key technical decisions and progress to keep the team aligned as the platform takes shape.

  • Collaborate with the team and other stakeholders to validate deliverables and incorporate feedback.

We are looking for you, if you have:

  • Fluent English — written and verbal (working language of the team).

  • Fullstack profile — comfortable with both front-end (JS/Vite or similar) and back-end/integration work.

  • Experience with REST APIs, OAuth 2.0, and app registrations.

  • Secure credential management — key vault, environment variables, never in front-end code.

  • Able to build and demo with mock/offline data while waiting for real API access.

  • Independent and proactive — able to lead technical conversations with IT without hand- holding.

  • Strong communication skills — can explain technical decisions to a non-technical audience.

  • Available for at least 5–6 hours of overlap with European timezone (CET/GMT) daily.

Nice to Have

  • Familiarity with Microsoft 365 ecosystem (Graph API, SharePoint, Power Automate).

  • Experience with Jira REST API or Atlassian ecosystem.

  • Knowledge of ServiceNow Table API.

  • Experience deploying to AWS or similar cloud environment.

We offer:

  • Participation in interesting and demanding projects.

  • Flexible working hours.

  • A great, non-corporate atmosphere.

  • Possibility to work remote or hybrid (2 days per week from the office).

  • Opportunities for development and promotion.

  • Attractive package of benefits.

We reserve the right to contact the selected candidates.
