Engagement Overview
Inflect is engaging an independent Backend Engineer Consultant in Brazil through Rippling (acting as a Contractor of Record) 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.
Who We Are
We are a US-based advisory and marketplace that is revolutionizing the way companies buy and sell digital infrastructure (Datacenter, cloud, and network services). Digital infrastructure services are the building blocks of the internet and at the core of every industry. Traditionally it’s been bought manually through service provider sales people, resulting in high costs, slow procurement cycles, and services that aren’t the best fit - slowing down the ability of companies to build and innovate.
Inflect’s marketplace and advisory are removing friction so any company can get what they need, when they need it, with the right deal terms. By achieving our mission, we unlock businesses to build and human innovation to inflect!
Specialized Technical Capabilities Required
- Backend & API Integration Mastery: 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.
- Adapter & Tooling Engineering: Practical experience building provider adapters, schema mapping tools, validation guardrails, and message-queue/event-driven architectures.
- Modern Integration Stack (Node/TS & LLMs): Exposure to Node.js/TypeScript backend tooling, LLM/agent integration frameworks, and GUI tooling to support self-serve adapter automation.
- Cross-Border Async Collaboration: Fluent professional English communication skills for effective cross-border async collaboration, code reviews, and daily alignment across Brazil, Poland, and US time zones.
Scope of Services & Project Deliverables
- Gateway & Adapter Service Delivery: Architect, build, and maintain Go-based backend services and provider adapters for network, bare-metal/GPU, and data providers (live pricing and availability).
- Self-Serve Onboarding Frameworks: Contribute to schema mapping frameworks, GUI tooling, validation guardrails, and LLM-assisted integration frameworks that allow non-engineers to onboard providers with minimal overhead.
- Adapter Maintenance & Observability: Own assigned adapter surfaces end-to-end under pod technical standards, delivering well-tested, highly observable services while maintaining existing adapter logic.
- Cross-Pod Alignment: Collaborate asynchronously across distributed functions (Design, QA, Data Foundation) to deliver reliable gateway integrations with US business hours overlap.
- Technical Advisory & Standards: Conduct code reviews, pull-request assessments, and technical documentation updates to uphold engineering quality across the pod.
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.
Engagement Terms & Compliance Structure
- Contract Type & Rate: Fixed-rate monthly Independent B2B Service Agreement executed via Rippling, $5,000-$6,500/mo based on experience
- Invoicing & Tax Compliance: Contractor must maintain an active corporate entity (Pessoa Jurídica - PJ / CNPJ) in Brazil and upload valid electronic service invoices (Nota Fiscal de Serviços Eletrônica - NFS-e) into Rippling for monthly disbursement.
- Autonomy: Complete flexibility over work schedules, location, and execution methods necessary to fulfill project deliverables and agreed milestones; holds no direct people-management, hiring, or employee reporting lines.
- Commercial Relationship: Strictly B2B consulting engagement; no employment relationship under the Consolidation of Labor Laws (CLT), paid vacation, 13th salary, or statutory employee benefit guarantees implied.

What We Do
We’re revolutionizing the way companies buy and sell digital infrastructure, and we’re extremely proud of that. Digital infrastructure is the enabler of the internet and at the core of every industry. Traditionally it’s been bought manually through service provider sales people, resulting in high costs, slow procurement cycles, and services that don’t work the best - slowing down the ability of companies to build and hold back human innovation. Inflect’s marketplace and advisory are removing friction so any company can get what they need, when they need it, at the right deal terms. By achieving our mission, we unlock businesses to build and human innovation inflects! Of course, we’re also a startup, and it’s important that you understand what that means if you work for us. We work quick, we work smart, we work hard, and the road to success is filled with some of the highest highs, but also has its fair share of lows. If you’re looking for the same thing day in and day out, this will not be the place for you. (And that’s totally okay!) We’re all owners of Inflect -full time employees receive option grants-, and we know that we’re the reason we’ll achieve our goals, or we’ll be the reason we don’t. So believe me when I say that we’re hell bent on achieving our goals. If this sounds like the kind of environment you would thrive in then we’d love to have you!
