About this role

Within the Aladdin Product Group – Private Markets, we are hiring a Senior Software Engineer to work on our Private Markets application suite. The position is based with our London team and operates as part of a broader team distributed across several countries worldwide.

This team works with other London based agile teams to build BlackRock's strategic Private Markets platform, including data collection and validation tools. It is built on a modern, cloud-native architecture leveraging Java as the core language.

The role is a hands-on senior individual contributor. It requires deep understanding of the technical aspects of a web-based software deployed in the cloud, strong software architecture knowledge, and advanced understanding of the Product Delivery Life Cycle. AI is at the heart of this role — both as embedded capabilities within the client facing product and as a core methodology in how we design, build, and ship software (AI-augmented development, AI-driven code generation, and AI-assisted quality assurance).

About You

You are an experienced software engineer who is comfortable working on large, greenfield, long-lived systems where correctness, traceability, and operational stability matter as much as delivery speed. You enjoy understanding how data flows through systems, how workflows interact across services, and how design decisions affect our clients. You can work autonomously in complex codebases, while collaborating closely with peers across engineering, product, and QA.

You embrace AI as a force multiplier - both in the product you build and in how you build it. You are not afraid to work on large codebases, leveraging AI-powered tools and copilots to understand, enhance, fix, and develop new product features at pace. You actively seek ways to integrate AI capabilities into product workflows and development processes, viewing AI as a first-class engineering discipline.

As a senior engineer, you contribute through hands-on development, sound technical judgement, and constructive collaboration, rather than through formal authority. You take ownership of the quality of your work and understand the impact it has on business-critical workflows used by investment analysts and data stewards managing billions in private market assets.

Technologies You Will Work With (Hands-On):

Java 21 and associated Frameworks (SpringBoot, Hibernate etc), Kubernetes, Azure Cloud, and associated PaaS services, SQL Server, React/Typescript, OAuth.

What You Will Be Doing

• Designing and implementing features within the Private Markets platform, focusing on enhancing the platform's data collection and management workflows.
• Building client facing web applications to enable these workflows, including building and integrating new back-end services to support them.
• Leveraging AI in your development workflow - using AI-powered IDEs, copilots, and code generation tools as standard practice to maximize productivity, accelerate code comprehension, and deliver quality features on time
• Working across the full software lifecycle, including development, testing, deployment, monitoring, and incident investigation
• Contributing to the evolution of core platform architecture - modular monolith patterns, micro-frontend orchestration, gRPC API design, and cross-service event-driven workflows
• Writing clear, maintainable code and contributing to automated testing and CI/CD pipelines with quality gates
• Diagnosing issues in existing systems, including integrations with internal platform APIs and downstream reporting and analytics systems, and improving them incrementally and safely
• Participating actively in code reviews and technical discussions, championing best practices in both traditional engineering and AI-augmented development
• Collaborating closely with engineers, architects, product partners, and QA across locations

Ideally you should have..

• A bachelor’s degree in computer science, engineering, or a related field.
• 7+ years of professional experience in Java development, with a focus on building client‑facing APIs or platforms
• Strong written and verbal communication skills, with experience managing and mentoring diverse teams.
• Familiarity with AI‑driven development practices and tools for code generation and testing (Claude, Devin, Copilot etc.)
• Knowledge of building applications using AI tooling and frameworks (e.g. LLM integration, prompt engineering, agents, skills).
• Strong proficiency in Java and related frameworks (e.g. Spring Boot, Hibernate).
• Some experience in React or similar, and modern JavaScript/TypeScript an advantage.
• Solid experience with object‑oriented design and applying standard design patterns.
• Experience designing, building, and deploying scalable microservices using API‑first principles with REST and/or gRPC.
• A strong appreciation for best practices, attention to detail, and building secure and stable systems.
• A collaborative mindset, with a drive to build high‑quality software efficiently.
• Experience with API authentication and authorisation mechanisms (e.g. OAuth, JWT).
• Hands‑on experience with engineering tools such as Git, Maven, unit and integration testing frameworks, and mocking libraries.
• Excellent problem‑solving skills and attention to detail.
• Exposure to Docker, Kubernetes, and cloud services in an enterprise environment is beneficial.
• Experience with message brokers such as Kafka a plus.
• A friendly, positive, and can‑do attitude.
• Strong ability to independently navigate and understand complex, existing codebases — including with the aid of AI tools
• Solid analytical and problem-solving skills, particularly in data-centric and workflow-driven systems
• Experience working on systems where data quality, auditability, and operational reliability are critical
