About the role

Key responsibilities & impact

Architectural Blueprinting: Define and maintain the overarching architectural vision, designing blueprints for scalable, distributed, and highly available systems.
Technical Governance: Establish technical standards, coding guidelines, and architectural guardrails, ensuring compliance across multiple engineering squads.
Technology Evaluation: Lead the evaluation, prototyping, and selection of modern tools, platforms, and frameworks (such as choosing between monolithic vs. microservices, or specific database technologies).
Cross-Functional Alignment: Partner with Product Managers, Security Officers, and Engineering Leads to translate complex business strategies into viable, future-proof technical roadmaps.
Risk & Performance Management: Conduct architectural reviews and root cause analyses on system bottlenecks to optimize for latency, throughput, and cost-efficiency.
Mentorship & Advocacy: Champion engineering excellence by mentoring Tech Leads and Senior Developers, fostering a proactive and autonomous engineering culture.

Requirements

What you’ll need

Professional Experience: 8+ years of experience in software engineering, with at least 3+ years acting in a dedicated System Architect or Principal Engineer capacity.
Architectural Mastery: Deep knowledge of enterprise integration patterns, microservices architecture, Event-Driven Architecture (EDA), and Domain-Driven Design (DDD).
Cloud & Infrastructure: Hands-on expertise architecting cloud-native solutions on AWS, Azure, or GCP, including serverless computing, container orchestration (Docker, Kubernetes), and Infrastructure as Code (IaC).
Data Architecture: Strong understanding of relational databases (SQL Server, PostgreSQL) and NoSQL solutions (MongoDB, Redis, Cassandra), knowing when to apply each model.
Security & Compliance: Proven track record of designing secure systems, factoring in identity management (OAuth/OIDC), data encryption, and network security layers.
Language: Advanced English proficiency (fluent verbal and written communication).
Nice-to-have Skills:
DevOps Mastery: Advanced experience with CI/CD automation, service meshes (e.g., Istio), and system observability tools (Datadog, Prometheus, ELK stack).
Legacy Decoupling: Proven experience applying patterns (like the Strangler Fig pattern) to systematically migrate legacy monoliths to modern architectures.
AI/Data Streaming: Familiarity with heavy data streaming tools (Kafka, RabbitMQ) or high-scale AI infrastructure pipelines.
Certifications: Professional certifications such as AWS Certified Solutions Architect Professional, Azure Solutions Architect Expert, or TOGAF.
