About Us

Ascent has recently been acquired by Acuity Analytics. This is both a significant milestone for us and a tremendous opportunity for you.

Acuity Analytics is a business with a strong global reputation, an impressive client base, and ambitious growth plans. We deliver deep insights and domain-led digital transformation to high-growth and heavily regulated organisations. To our customers, we bring a partnership that provides the talent, technology, and capability to enhance performance and operational efficiency.

As part of our continued growth, we are looking for a Solutions Architect to define enterprise-grade application solution architecture for large-scale legacy modernization initiatives within a Banking & Capital Markets environment.

About the Role

You will be responsible for assessing complex existing application and integration landscapes, particularly Microsoft technology-based estates, identifying modernization opportunities, and designing scalable, resilient, secure, maintainable and cloud-agnostic target solutions aligned to business capabilities and enterprise architecture standards.

You will bring strong functional understanding and technical depth to translate business workflows, operating processes, integration dependencies, data flows, control points, reporting requirements and non-functional needs into practical modernization blueprints. The role involves defining migration-ready architecture patterns across.NET, C#, Microsoft SQL Server, Azure and related Microsoft-based technologies, evaluating technology options, guiding engineering teams, and ensuring solutions address scalability, availability, disaster recovery, RPO/RTO, security, auditability, observability, operational resilience and long-term supportability.

Responsibilities

Lead enterprise solution architecture for legacy modernization initiatives covering business capabilities, application architecture, integration, data, cloud, security, DevSecOps, observability and operational supportability.
Assess existing application portfolios, monolithic platforms, shared databases, batch processing flows, integration dependencies, reporting workloads and operational constraints to define modernization priorities and solution options.
Understand business processes, user journeys, data flows, upstream/downstream dependencies, reporting needs, control requirements and operational pain points to shape fit-for-purpose enterprise solution designs.
Translate functional and non-functional requirements into modernization roadmaps, architecture decisions, solution blueprints, integration patterns, service boundaries, data models, deployment views and implementation guidance.
Architect enterprise-grade application solutions using microservices, domain-aligned service design, API-first integration, event-driven workflows, service-owned databases and containerized runtime models.
Design enterprise integration solutions using Kafka, IBM MQ, REST APIs, gRPC, FIX, SFTP, schema registry, canonical events, adapters, retries, idempotency, dead-letter handling and reconciliation patterns.
Architect cloud-native and platform-agnostic solutions using Kubernetes, Docker, OpenShift, AKS/GKE or equivalent platforms, with appropriate runtime, networking, secrets, identity, deployment and portability considerations.
Provide Azure-focused architecture guidance including Azure landing zones, compute, networking, identity, security, monitoring, deployment, integration and migration patterns for enterprise application modernization.
Provide architecture guidance for application-facing data needs including data access patterns, reporting integrations, data contracts, auditability, lineage awareness and alignment with enterprise data platforms.
Define and review technical designs involving.NET, C#, WPF, Microsoft SQL Server, PostgreSQL, Redis, middleware, reporting platforms, stored procedures and modernization of legacy Microsoft-based enterprise applications.
Assess and document non-functional requirements including performance, scalability, latency, availability, resilience, disaster recovery, failover, security, auditability, monitoring and operational support.
Define high availability and disaster recovery architecture including active-active or active-passive patterns, failover design, backup and restore strategy, cross-region or cross-cloud resilience, RPO/RTO targets and business continuity considerations.
Support phased modernization planning including strangler pattern, coexistence with legacy systems, parallel run, data reconciliation, cutover readiness, rollback planning, risk mitigation and legacy decommissioning considerations.
Facilitate solution discussions with business, product, operations, risk, compliance, data, infrastructure, security, DevOps, QA and client technology stakeholders to align scope, priorities, dependencies and delivery outcomes.
Create architecture artifacts such as current-state assessments, high-level designs, target-state blueprints, interface specifications, sequence flows, deployment views, data flow diagrams, technology decision records and architecture summaries.
Work with engineering teams to ensure solution designs are implementable, testable, observable, secure, migration-ready and aligned with enterprise architecture standards.
