Forward-deployed Engineer

We're looking for a Forward-deployed Engineer to sit at the intersection of Product Engineering and our Go-To-Market teams, embedded directly with partners and customers to ship integrations fast, acting as the primary technical owner for every integration in your portfolio. You'll own the full integration lifecycle from qualification to handoff, working hands‑on with technical and non-technical stakeholders on both sides. You'll write real code, shape the integration framework, and feed patterns back into the platform.

Responsibilities

• Own the full integration lifecycle for partners and customers who need hands‑on delivery support, qualification, scoping, build, and handoff
• Run Phase 0 qualification assessments — mapping systems, data flows, risk surface, and build approach before committing to timelines
• Build and configure integration connectors, data mappings, and partner adapters using Clara's integration framework and shared libraries
• Coordinate directly with partner technical teams throughout the build, acting as the primary technical point of contact
• Partner with Platform/API squads to leverage core primitives (webhooks, auth patterns, event contracts) and flag reuse opportunities
• Ensure every integration meets Clara's standards: idempotency, observability, secrets management, data minimization, and sandbox testing
• Drive clean handoffs — delivering runbooks, dashboards, on‑call assignments, and support playbooks before marking an integration as done
• Feed learnings back into the platform: identify patterns that should become shared libraries or configuration

Who you are

Must haves

• Experience working directly with external partners or customers in a technical capacity, you're comfortable owning the relationship, not just the code
• Working directly with end customers
• Designing the solution from scratch to meet customer needs
• Great communication skills
• 4+ years of backend software development experience, with hands‑on exposure to API integrations, webhooks, and data mapping
• Deep fluency in integration patterns: REST, event‑driven architectures, OAuth/token management, idempotency
• Ability to move fast in ambiguous environments: qualify a new integration request, scope it, and start building within days
• Strong proficiency in one or more backend languages (preferably Java) and comfort working across multiple systems and tech stacks
• Working knowledge of observability fundamentals: logs, metrics, tracing, alerting, and SLOs
• You use AI tools as a force multiplier, from scaffolding connectors to automating repetitive mapping work
• Working proficiency in English and Spanish, or English and Portuguese
• Excellent communication skills with both technical and non-technical audiences
• Exposure to integration platforms or connector frameworks (e.g. N8N, Zapier, or custom‑built equivalents)

Nice to haves

• Experience in fintech, payments, or financial data infrastructure
• Familiarity with PCI/PII data handling and compliance requirements
• Experience with AWS, Kafka, or event streaming platforms
• Proficiency in all three languages (Portuguese, Spanish, and English) is a strong plus

A good sense of humor
