Descrição da oferta de emprego

Company : Fraud Deflect Role : Senior Software Engineer

Language : Native / fluent English. Resumes in English.

About the role

Own and evolve critical payments / back-office services end-to-end : design, build, ship, and operate API-first Python systems that automate disputes / chargebacks and related workflows. You'll partner directly with clients and internal teams to translate business rules into reliable integrations, services, and data models—leveraging Linux, with a pragmatic DevOps mindset.

Responsibilities

• Lead project execution : technical design, implementation plans, code reviews, and delivery coordination.
• Build and operate REST APIs in Python (versioning, idempotency, auth, webhooks, integrations).
• Own API integrations with external partners / processors : onboarding, validation, retries, error handling, and SLAs.
• Implement complex payments / chargeback business logic from requirements and client workflows; ensure correctness and auditability.
• Model API / domain data with strong data-structure fundamentals (schemas, invariants, normalization / denormalization tradeoffs).
• Meet and maintain contact directly with clients.
• Operate services on Linux : deployments, debugging, performance tuning, incident response, and reliability improvements.
• Contribute to DevOps practices : CI / CD pipelines, safe rollouts, observability (logs / metrics / traces), and operational automation.

Required

• Expert Python backend engineer (3.12+ preferred) : strong typing, testing, concurrency fundamentals, and performance debugging.
• Proven REST API development experience (design + production operations), including integrations and webhooks.
• Strong data structures and API data modeling skills (clear contracts, backward compatibility, validations).
• Experience implementing business logic for payments / fintech workflows, especially disputes / chargebacks and reconciliations.
• Comfortable on Linux servers with a DevOps mindset (deploy / run / debug production services; automate operational work).
• Client-facing technical communication : can interface with external stakeholders to clarify requirements, diagnose issues, and drive resolutions.
• Ownership mentality and interest in leadership : drive the full lifecycle from discovery → design → build → operate.

Nice to have

• Containerization / orchestration (Docker / Kubernetes), IaC (Terraform), and cloud-native operations on Amazon Web Services.
• Event-driven / workflow systems (SQS / Kafka / Kinesis; Airflow / Prefect / Dagster).
• Security / compliance exposure (PCI, SOC 2) and observability tooling at scale.

How to apply

Send an English resume and links to relevant work (repos, API docs, architectural notes, or write-ups) showing :

• Python backend API development + real-world API integrations
• Payments / disputes / chargebacks or similarly complex workflow automation
