Descrição da oferta de emprego

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
