📋 Description

• Move fluently across multiple programming languages and ecosystems beyond our core stack (not limited to Python or Django) to read, adapt, and extend integration-specific code such as ERP scripting frameworks (e.g. SuiteScript), native app extensions for accounting and finance platforms, and third-party vendor SDKs. • Work confidently with a wide range of authentication and identity flows, including OAuth 2.0 / OIDC, SSO providers (Microsoft Entra ID, Okta, Google Workspace), SAML, and service-to-service authentication. Comfortable managing different token types (access, refresh, JWT, API keys), handling token lifecycles, and applying secure communication protocols (TLS/HTTPS, signed requests, secret management) across all integrations. • 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 (e.g. connector builder, declarative DSLs, LLM-assisted workflows), and choose between integration strategies (unified API, in-house, contractors) to accelerate integration development and maintenance. • Ensure integrations are secure, resilient, and performant at scale, supporting high-volume financial and transactional data. • Collaborate closely with product, design, financial experts, and customers to translate complex, ambiguous workflows into intuitive software experiences. • Establish technical standards, and guide architecture for integrations and data-heavy systems.

🎯 Requirements

• 7+ years of experience, at least 2+ of which are on integrations roles • 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 similar large-scale API ecosystems. • Curiosity and persistence in 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. when to invest in foundational architecture.

🏖️ Benefits

• Competitive compensation including equity package • Competitive vacation policy • Access to Meditopia • Hybrid working model and flexible working hours • Personal development including language courses
