Descrição da vaga

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).
• Develop and maintain client‑facing device intelligence instrumentation in JavaScript where needed (collection, privacy controls, performance).
• 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

• JavaScript experience beyond basics (instrumentation, performance, privacy‑aware collection) for client integrations.
• 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
• Linux/DevOps experience running production services
• Any JavaScript instrumentation work and client‑facing delivery experience
