3Pillar warmly extends an invitation for you to join an elite team of visionaries. Beyond software development, we are dedicated to engineering solutions that challenge conventional norms. Envision you: steering projects that redefine urban living, establish new media channels for enterprise companies, or drive innovation in healthcare. Your invaluable expertise will serve as the cornerstone in shaping the future direction of our endeavours. This role is the primary expert within a technology stack. The Architect owns the decision making around high-level design choices and dictates technical standards, including software coding standards, tools, and platforms. The ideal candidate will thrive in a collaborative environment and be engaged in the development process.
Key Responsibilities:
Act as the emissary of the architecture.
Technical owner from design to resolution of tailored solutions to sophisticated problems on cloud platforms based on client requirements and other constraints.
Partners with appropriate stakeholders to determine functional and nonfunctional requirements, as well as business goals, for a set of scenarios.
Assess and plan for new technology insertion.
Manage risk identification and risk mitigation strategies associated with the architecture.
Active leader in the Architecture Practice community, mentoring Engineers and others through Communities of Practice (CoPs) or on project teams, supporting the growth of technical capabilities.
Develop and execute or lead the execution of a technical vision, within one or more business or technical domains, with a focus on the business value.
Design architectures that align with the DevOps culture and QA Automation practices.
Minimum Qualifications:
A Bachelor’s degree or higher in Computer Science or a related field.
Architect would require a deep and highly specialized skill set in telecommunications architecture, cloud-native development, and systems modernization.
A minimum of 10+ years of experience/expertise working as a Software Architect and/or Solutions Architect, with proficiency in the specified technologies:
Legacy-to-Cloud Migration: Proven experience leading the re-platforming and iterative, low-risk migration of legacy C++ systems to modern Java/Cloud-Native platforms.
Performance Engineering: Ability to design for and achieve high-throughput, low-latency performance targets (e.g., matching or exceeding 7,000–8,000 Events Per Second (EPS)).
Telecom Protocols: Deep knowledge of complex telecom libraries and protocols, specifically TCAP and Diameter, including designing necessary abstraction layers to maintain their use in a new platform.
SDS Ecosystem: Familiarity and adherence to the SDS platform, FSMApp programming model, and non-blocking I/O patterns.
Cloud-Native and Scaling Strategy
Cloud-Native Network Function (CNF): Expertise in defining and implementing CNF architecture, ensuring deployment across major cloud platforms (AWS, Azure, GCP).
Container Orchestration: Strong command of Kubernetes, including defining resources (Deployment, Service) and configuration for horizontal scaling.
Sticky Session Routing: Deep understanding of load balancing and ingress layer concepts to implement IMSI-based affinity for session routing.
State and Data Management
Hybrid State Model Design: Expertise in architecture patterns that combine stateless external persistence with local in-memory caching.
Distributed Caching: Hands-on experience with Redis-compatible distributed cache services (e.g., ElastiCache, Azure Cache, GCP Memorystore) for high-availability.
Cache Architecture: Design and implementation of a two-tier cache architecture (L1 local cache, L2 distributed cache) for low-latency subscriber profile access.
Data Abstraction: Profound understanding of the Repository pattern to abstract and swap underlying cache and persistence implementations without altering core business logic.
Consistency: Understanding and managing data consistency models, particularly accepting Eventual Consistency for reference data caching.
Quality, Observability, and Governance
Quality Gates & Testing Strategy: Defining and enforcing rigorous quality control, including a systematic 7-step porting pattern and requirements for Characterization Testing (Golden Master Testing).
CI/CD Implementation: Designing and enforcing a Mandatory CI/CD Pipeline with strict quality gates (e.g., 100% golden master match, $<10%$ performance regression).
Observability Stack: Architecture design for Metrics Export, Distributed Tracing, and Structured Logging across the new microservices platform.
Security Integration: Knowledge of cloud-native security practices, specifically Secrets Management and Network Policies.
Architectural Governance: Serving as the final architectural authority to review, approve, and guide key design and commercial decisions with the client.
Additional Experience Desired:
Ideal candidate would serve as the technical authority for the project, guiding major design decisions and ensuring the new platform meets performance, scalability, and quality criteria.
Contribute to code reviews, documentation and architectural artifacts.
Provide leadership and oversight to the project team pertaining to solution design.
