JOB TITLE: Senior Solutions Architect
SALARY: £107,304 - £138,864
LOCATION: London
HOURS: Full Time
WORKING PATTERN: We adopt hybrid working style which involves spending at least two days per week, or 40% of our time, at our London, Gresham Street office.
About this opportunity
Personalised Experiences and Communications (PEC) is a business platform within Consumer Relationships that supports the Group's strategic goals by deepening customer relationships. PEC delivers personalised communications and experiences across all channels and business areas, enabling the Customer Relationship Growth strategy for both retail and commercial banking. It also drives data, analytics, and technology to enhance branded experiences, propositions, pricing, and sustainable, paper-free ambitions.
We're scaling a bank wide real-time decisioning capability to power time decisioning capability to power next best experiences across digital, colleague and outbound channels. We're building the "decisioning brain" that integrates AI and adaptive models, engagement policies and channel orchestration - underpinned by modern data foundations on GCP and event streams (e.g., Kafka).
In this role, you'll be the end-to-to-end solution authority for decisioning within the PEC Platform: shaping how Decisioning Ecosystem (NBA, engagement/contact policies, arbitration) integrates with our data platform and channels, ensuring designs meet demanding nonfunctional targets (latency, resilience, cost effectiveness, security and observability), and setting guardrails and patterns that squads and partners can use to deliver at pace-safely and consistently.
What you'll be doing…
Own solution architecture for real-time decisioning
Define and evolve E2E designs spanning Decisioning Ecosystem (NBA Designer, arbitration, contact/frequency policies), data access layers, and channel integrations (web/app, colleague, outbound). Ensure loose coupling to support progressive evolution of the stack.
Integrate decisioning with modern data & signals
Architect data flows across GCP (e.g., BigQuery, streaming), Kafka/eventing, and digital signal sources (e.g., Tealium/Celebrus) to provide sub-second second context for decisions and feedback loops for learning.
Set NFRs & SLOs for scale
Translate business outcomes into measurable performance targets (e.g., p95 latency, availability, change failure rate, cost per decision) and ensure designs, environments and runbooks meet them.
Establish reusable patterns and guardrails
Publish reference architectures, ADRs and integration patterns (APIs, events, identity, consent, measurement) and steward them through Design Authority and platform governance.
Champion security, privacy & compliance
Embed threat-modelling, data minimisation, consent modelling, modelling, data minimisation, consent and auditability into the designs; ensure explainability and fairness considerations are factored into decisioning choices and model usage.
Partner across labs & vendors
Work closely with product engineering squads, data science/ML teams, platform engineering, InfoSec, and delivery partners to land pragmatic solutions and accelerate value.
Roadmap & technical direction
Contribute to the PEC architecture roadmap, including where we keep vendor capabilities vs. build inhouse over time, ensuring we can iterate safely without vendor lock-in.
How we work:
Product-led lab model with autonomous squads, clear guardrails and fortnightly demos-optimising for rapid, safe iteration.
Strong governance & measurement culture: transparent change processes, defined success metrics (uptime/SLA, time-to-release, policy compliance, incremental uplift).
Hybrid, collaborative ways of working across UK and our global technology centres.
Why Lloyds Banking Group.
We're on an exciting transformation journey and there could not be a better time to join us. The investments we're making in our people, data, and technology are leading to innovative projects, fresh possibilities and countless new ways for our people to work, learn, and thrive.
What you'll need:
Deep architecture experience in real-time decisioning, personalisation or marketing tech at scale in a regulated environment.
Modern data & integration: event driven architectures (Kafka), streaming & batch patterns, API design, identity resolution, experimentation/measurement pipelines.
Knowledge and experience designing distributed systems (fault tolerance, scaling/partitioning, consistency models and trade-offs, retries/idempotency/backpressure), including high availability and multi-zone/region patterns.
Knowledge and experience of public cloud providers (GCP/AWS/Azure): core networking/VPC, IAM and security controls, service-to-service connectivity, managed data/streaming services, observability and cost governance/FinOps.
Cloud & engineering foundations: CI/CD, Infrastructure-as- code, observability, reliability engineering, performance engineering and cost governance.
Architecture practices: C4 modelling, ADRs, threat modelling, zero trust/data security by design, and effective governance communication.
And any experience of these would be useful:
Handson Pega CDH expertise (or equivalent RT decisioning platform): NBA strategy/arbitration, engagement policies, taxonomy/guardrails, simulation and change governance.
Knowledge and experience of Google Cloud Platform (GCP) - BigQuery, Pub/Sub, Dataflow (Apache Beam), Cloud Run/GKE, Cloud Functions, IAM, VPC/Private Service Connect, Cloud Logging/Monitoring, Secret Manager and Org Policies.
Experience with digital signal & CDP ecosystems (e.g., Tealium/Celebrus, Adobe/AEP/AJO) and content & experience assembly (e.g., AEM, inhouse mapping via Phoenix).
ML/MLOps familiarity (model monitoring, explainability, bias/fairness controls, offline/online learning, experimentation at scale).
Prior work in largescale, multi brand contexts (contact policies, suppression, pressure rules, governance).
