• Work 100% remotely, based in Portugal; • Collaborate with global teams to develop innovative solutions; • Execute and deliver high-quality projects within established deadlines; • Participate in team meetings and contribute to technical strategy.

• Lead architectural design and technical strategy for major components of the legacy-to-serverless migration. • Direct AI agents to produce production-quality Node.js / TypeScript code - framing the work, reviewing the output rigorously, and owning the result. You hold the bar for correctness and maintainability. • Conduct deep analysis of existing systems to inform migration scope, sequencing, and risk - and verify that AI-assisted analysis is accurate before decisions are made on it. • Define data migration strategies - schema design, ETL patterns, data validation - for SQL workloads moving to modern storage solutions. • Build and maintain robust APIs, event-driven workflows (SQS, EventBridge, SNS), and integrations with external partners. • Drive technical excellence across the team: establish coding standards (for humans and AI alike), conduct design reviews, and champion automated testing. • Mentor and upskill Senior and Mid-level engineers - including how to work effectively with AI - and provide actionable feedback. • Collaborate with product, design, and QA to make sure what we deliver actually solves the business problem, with minimal disruption to production. • Support and triage production issues across legacy and new platforms during the transition period.

• Drive the future of Subquadratic’s customer-facing stack. • Architect the full-stack systems required to stream real-time audio and LLM tokens to the browser. • Build self-serve onboarding flows, interactive API playgrounds, and observability dashboards. • Partner directly with Product and Research leadership to translate experimental AI capabilities into stable, production-ready product features.

• Design and implement services that support revenue workflows, payment logic, and invoicing pipelines • Build robust APIs and ful-stack features using Node.js, Next.js, TypeScript, GraphQL, and PostgreSQL, leveraging type-safe ORM tooling (Drizzle or Prisma preferred) for schema management and query composition • Own integration with internal systems (e.g., Salesforce, NetSuite) and external providers (e.g., banks, payment processors) • Implement structured financial logic such as contingent payments, commission calculations, and milestone-based billing • Integrate AI/LLM capabilities using Claude (Anthropic) and leverage Cursor as a core development tool to accelerate delivery • Build and deploy infrastructure in AWS using services like Lambda, ECS/EKS, RDS, SQS, and EventBridge • Implement CI/CD workflows and monitoring across environments • Ensure systems are fault-tolerant, scalable, and auditable, with proper instrumentation and alerting • Translate complex business rules into deterministic backend logic: commissions, milestones, payee splits, and contingent payments • Implement robust data flows between Client Processing, Deal Management, and Authoritative Data domains • Ensure data integrity across subsystems handling trust accounting, revenue posting, and contract lifecycle events • Work closely with product managers, architects, and finance stakeholders to deliver end-to-end features • Translate financial and contractual rules into deterministic, reusable service logic • Drive quality, automation, and performance in a domain where correctness and compliance are critical
