About the role

Role focuses on building and scaling Abacum’s integrations platform, bidirectional connectors with ERP/accounting systems, low-code tooling, and secure, high-volume data handling.

Responsibilities

  • Move across multiple programming languages and ecosystems beyond the core stack to read, adapt, and extend integration-specific code (ERP scripting frameworks, native app extensions, third-party SDKs).
  • Work with authentication/identity flows (OAuth 2.0 / OIDC, SSO providers, SAML, service-to-service auth) and manage token lifecycles and secure communications.
  • Lead the design and development of Abacum's integrations platform for ingesting, normalizing, and annotating business data.
  • Build and scale bidirectional integrations with billing, accounting, ERP, commerce, and HRIS platforms.
  • Architect low-code/no-code tools (connector builder, declarative DSLs, LLM-assisted workflows) and decide integration strategies to accelerate development and maintenance.
  • Ensure integrations are secure, resilient, and performant at scale for high-volume financial data.
  • Collaborate with product, design, financial experts, and customers to translate complex workflows into intuitive software experiences.
  • Establish technical standards and guide architecture for integrations and data-heavy systems.

Qualifications

  • Strong background in building integrations for data-heavy use cases
  • Hands-on depth in Python and modern backend systems
  • Experience architecting or working on integrations platforms, data platforms, or large-scale API ecosystems
  • Curiosity and persistence tackling ambiguous, high-stakes technical problems like low-code builder design, LLM-assisted workflows, and data enrichment
  • Pragmatic judgment: know when to ship quickly vs. invest in foundational architecture
