[Hiring] Backend Engineer Consultant @Inflect

Role Description

Inflect is engaging an independent Backend Engineer Consultant in Brazil through Rippling to build, deliver, and maintain provider adapters and gateway backend services that onboard new supply providers into the marketplace. This is an autonomous, high-impact consulting engagement focused on API integration architecture, Go backend service delivery, and supporting the migration from bespoke adapters toward self-serve provider onboarding workflows.

Working as an external subject matter expert, you will provide technical execution across the Integrations & Gateway surface, ensuring our marketplace supply ingestion, pricing engines, and adapter services run with high availability, observability, and automated resiliency.

Qualifications

• 3–5 years of professional backend development with production expertise in Go (or strong adjacent languages with a rapid ramp to Go)
• REST/API integrations
• Postgres, Redis, and cloud infrastructure on AWS
• Practical experience building provider adapters, schema mapping tools, validation guardrails, and message-queue/event-driven architectures
• Exposure to Node.js/TypeScript backend tooling, LLM/agent integration frameworks, and GUI tooling to support self-serve adapter automation
• Fluent professional English communication skills for effective cross-border async collaboration

Requirements

• Architect, build, and maintain Go-based backend services and provider adapters for network, bare-metal/GPU, and data providers (live pricing and availability)
• Contribute to schema mapping frameworks, GUI tooling, validation guardrails, and LLM-assisted integration frameworks that allow non-engineers to onboard providers with minimal overhead
• Own assigned adapter surfaces end-to-end under pod technical standards, delivering well-tested, highly observable services while maintaining existing adapter logic
• Collaborate asynchronously across distributed functions (Design, QA, Data Foundation) to deliver reliable gateway integrations with US business hours overlap
• Conduct code reviews, pull-request assessments, and technical documentation updates to uphold engineering quality across the pod

Benefits

• Fixed-rate monthly Independent B2B Service Agreement executed via Rippling, $5,000-$6,500/mo based on experience
• Complete flexibility over work schedules, location, and execution methods necessary to fulfill project deliverables and agreed milestones
• Strictly B2B consulting engagement; no employment relationship under the Consolidation of Labor Laws (CLT)

Definition of Success (What Strong Performance on Projects Looks Like)

• Production provider integrations and adapters are independently shipped and operating reliably in production
• At least one new supply provider group (network, bare-metal/GPU, or data) is successfully onboarded into the marketplace
• Self-serve onboarding frameworks and GUI/validation tooling measurably reduce manual engineering effort per provider
• An end-to-end slice of the gateway is reliably owned, well-tested, and maintained under pod technical standards
