Senior Architect

Key Responsibilities

Architecture & Technical Leadership

• Own end-to-end solution architecture for key product areas and cross-platform capabilities (e.g., pricing/promotions, inventory availability, order orchestration, customer/loyalty, POS integrations).
• Define and enforce architecture standards: layering, service boundaries, domain models, API guidelines, eventing patterns, and coding practices.
• Lead technical design reviews, architecture decision records (ADRs), and critical path technical risk assessments.
• Drive modernization initiatives (cloud readiness, decomposition, re-platforming, dependency rationalization, observability).

Platform & Integration Design

• Design integration patterns for enterprise retailers (APIs, events, batch, streaming, middleware), including partner and third-party ecosystems.
• Establish API strategy (REST/GraphQL where applicable), versioning, backward compatibility, and developer experience guidelines.
• Collaborate with Professional Services on reference architectures for implementations, upgrades, and complex customer integrations.

Non-Functional Excellence

• Ensure systems meet SLAs for performance, availability, resiliency, scalability, and security.
• Define patterns for caching, data consistency, idempotency, retries, rate limiting, and disaster recovery.
• Champion observability: logging, metrics, tracing, alerting, and operational runbooks.

Engineering Enablement & Mentorship

• Mentor senior engineers and tech leads; support career growth and raise engineering standards.
• Partner with QA and DevOps to embed quality and automation into the delivery lifecycle (shift-left testing, CI/CD controls).
• Contribute hands-on where needed (prototypes, spikes, performance investigations, complex fixes).

Stakeholder Collaboration

• Work closely with Product to align architecture with roadmap, cost, and delivery constraints.
• Communicate architecture trade-offs clearly to engineering leadership and non-technical stakeholders.
• Support presales and customer escalations when deep technical leadership is required.

Required Qualifications

• 10+ years of software engineering experience, with 3+ years in an architecture/technical leadership role.
• Strong expertise in distributed systems and service-oriented architectures (microservices and/or modular monoliths).
• Proven ability to design and deliver enterprise-grade solutions with clear documentation and governance.
• Experience with cloud and modern delivery practices: CI/CD, infrastructure-as-code concepts, containerization, and automated quality gates.
• Cloud exposure to AWS and AWS services
• Strong understanding of:
• API design, security, and versioning
• Data modelling and persistence (SQL/NoSQL) and integration patterns
• Performance engineering and troubleshooting in production systems
• Secure coding and threat modelling fundamentals
• Excellent communication and influencing skills across globally distributed teams.

Preferred Qualifications (Nice To Have)

• Retail domain experience: POS, OMS, pricing/promotions, inventory, returns, loyalty, taxation.
• Exposure to LLM integration patterns and MCP server contracts.
• AI tool exposure.
• Experience with event-driven architecture (e.g., Kafka), CQRS patterns, and workflow/orchestration concepts.
• Experience building platform capabilities for multi-tenant enterprise SaaS.
• Familiarity with zero-downtime deployments, blue/green, canary releases.
• Exposure to AI-assisted engineering practices (code quality, test generation, operational insights).

Tech Stack

• Backend: Java/.NET (as applicable), REST APIs, integration services
• Data: SQL + caching; eventing/streaming (where applicable)
• Cloud/DevOps: Docker, Kubernetes, CI/CD pipelines, observability tools
• Security: OAuth2/OIDC, secrets management, secure SDLC

Success Measures.

• Architecture standards adopted and measurable reduction in defects/rewrites.
• Improved service performance/reliability and clearer operational posture (dashboards, alerts, runbooks).
• Faster, safer delivery through reference architectures and reusable patterns.
• Stronger alignment across product, engineering, QA, and PS on implementation-ready designs.
