Sr. Platform Engineer

About the Role:

Fideo Intelligence transforms massive datasets into real-time fraud-detection insights that protect people and organizations worldwide. As our Senior Platform Engineer, you’ll own the end-to-end reliability and performance of Fideo’s real-time fraud-detection backbone. You’ll spend half your time architecting, securing, and operating our AWS environments, and half your time as a backend engineer building and optimizing microservices. Your work directly impacts our ability to process millions of events per day with sub-100 ms latency, maintain SOC 2 controls, and stay ahead of emerging threats.

You’ll drive AWS best practices, designing VPCs, IAM policies, networking, and container platforms (EKS/ECS), to ensure high availability and airtight security. You’ll lead vulnerability assessments, patch cycles and compliance initiatives, documenting controls and guiding audits to keep us SOC 2 ready.

On the code side, you’ll design, implement and tune Java microservices that power our streaming pipelines and customer-facing APIs. You’ll identify hotspots, refactor for scale, and instrument services with metrics, logs, and distributed tracing, turning data into actionable insights on demand.

Working on a tight-knit team of five engineers, you’ll wear multiple hats: automating CI/CD, defining SLIs/SLOs, responding to incidents, and evolving our observability framework. You’ll partner with product, data, and security leads to translate requirements into resilient, high-throughput systems, and mentor peers in both SRE and backend best practices.

Ideal Candidate:

Our ideal candidate is a hands-on engineer who is passionate about building reliable systems and thrives in high-performance environments. You are naturally curious, enjoy deep dives into complex problems, and excel at identifying and resolving issues in real-time systems. You are fluent in DevOps and AWS, and you seamlessly flex between operations and backend development to ensure our systems achieve and maintain high availability. You relish working on a small, agile team (we are five engineers) and wearing many hats to design, build, and operate scalable, resilient infrastructure.

Core Responsibilities:

• Cloud, Security & Compliance
  • Architect, deploy and maintain AWS (ECS, Lambda, VPC, IAM, RDS) tracking in Terraform
  • Lead security: vulnerability remediation, patch management, least-privilege policies
  • Drive SOC 2 compliance: implement controls, support audits, document processes
• Reliability & Automation
  • Define SLIs/SLOs; onboard services into observability (Prometheus, Grafana, ZenDuty)
  • Build CI/CD pipelines (GitActions, Docker), runbooks, and self-healing mechanisms
  • Diagnose and resolve incidents; conduct blameless postmortems
• Collaboration & Documentation
  • Partner with product, data, and security teams on architecture and feature delivery
  • Mentor peers in SRE best practices and backend clean-code principles
  • Document systems, workflows, and drive continuous process improvements
• Real-Time Pipelines & Streaming
  • Design and optimize low-latency, high-throughput data systems (Kafka, Scylla, MySQL)
  • Maintain and enhance data ingestion/delivery systems
• Microservices & APIs
  • Develop scalable, fault-tolerant services (Java, predominantly) handling thousands of RPS
  • Profile, refactor and tune for latency, resource utilization and horizontal scaling
  • Design, document and conduct disaster recovery reliability testing

Requirements:

• 6+ years engineering experience in real-time systems or platform roles
• 3+ years hands-on backend dev: Java, Scala, or Go
• Expertise with Kafka (or similar), event-driven architectures, and NoSQL (ClickHouse, Scylla, Cassandra)
• Proficiency with RDBMS (MySQL, PostgreSQL)
• Deep understanding of networking (DNS, load balancing, latency optimization)
• Solid AWS cloud expertise and cloud-native service deployment
• Skilled with CI/CD, Docker and Kubernetes or ECS
• Infrastructure as code: Terraform or CloudFormation
• Observable systems: Prometheus, Grafana, PagerDuty (or similar)
• Strong debugging skills for distributed, real-time applications
• Excellent communication and clear technical documentation

Nice to Have:

• Hands on experience working with ML models and AI
• Background in financial or fintech space with an understanding of fraud
