Join us as a Principal Engineer, at Barclays, where you will spearhead the evolution of our infrastructure and deployment pipelines, driving innovation and operational excellence. You will harness cutting-edge technology to build and manage robust, scalable and secure infrastructure, ensuring seamless delivery of our digital solutions.
To be successful as a Principal Engineer, you should have experience with:
- Deep hands‑on engineering experience building and scaling large‑scale systems on AWS, with strong expertise across services such as EKS, Lambda, Aurora, DynamoDB, Kinesis, MSK, S3, API Gateway, Step Functions, CloudWatch, IAM, and infrastructure‑as‑code frameworks (CloudFormation/Terraform).
- Proven ability to design and build high‑throughput, low‑latency distributed systems for mission‑critical workloads. Strong experience implementing cloud‑native, event‑driven, microservices‑based architectures.
- Strong engineering leadership with an emphasis on hands‑on contribution — including system design, coding, code reviews, design reviews, and setting engineering standards and best practices. Deep expertise in containerization, Kubernetes, serverless patterns, and multi‑region, fault‑tolerant systems.
- Experience leveraging frontier LLM models (e.g., Claude or similar) to improve engineering productivity and solution design. Proven ability to apply AI‑assisted development techniques across the software development lifecycle — including code generation, testing, documentation, and troubleshooting — driving measurable gains in developer efficiency, code quality, and delivery speed.
- Experience driving performance, scalability, resilience, and cost efficiency in cloud platforms. Ability to lead multiple technical initiatives in parallel, including proof‑of‑concepts, technical evaluations, and solution implementation.
Some other highly valued skills may include:
- Experience building fraud detection platforms, decisioning systems, or real‑time risk engines, ideally in high‑scale environments.
- Exposure to AI/ML platforms, LLM‑based systems, GenAI tooling, vector databases, and integrating these capabilities into production systems. Experience with streaming frameworks (e.g., Flink, Spark Streaming), graph technologies, and real‑time analytics.
- Understanding of model governance, cloud security best practices, and regulatory requirements (e.g., PCI, GDPR). Experience modernizing legacy systems into cloud‑native, microservices or event‑driven platforms.
- Experience leading or mentoring engineers across distributed or global teams, with a focus on technical excellence and delivery.
- Evidence of thought leadership through patents, publications, open‑source contributions, or speaking at technical forums.
You may be assessed on key critical skills relevant for success in role, such as risk and controls, change and transformation, business acumen, strategic thinking and digital and technology, as well as job-specific technical skills.
The role is based out of Pune.
Purpose of the role
To design, develop, and implement solutions to complex business problems, collaborating with stakeholders to understand their needs and requirements, and design and implement solutions that meet those needs and create solutions that balance technology risks against business delivery, driving consistency.
Accountabilities
- Design and development of solutions as products that can evolve, meeting business requirements that align with modern software engineering practices and automated delivery tooling. This includes identification and implementation of the technologies and platforms.
- Targeted design activities that apply an appropriate workload placement strategy and maximise the benefit of cloud capabilities such as elasticity, serverless, containerisation etc.
- Best practice designs incorporating security principles (such as defence in depth and reduction of blast radius) that meet the Bank’s resiliency expectations.
- Solutions that appropriately balance risks and controls to deliver the agreed business and technology value.
- Adoption of standardised solutions where they fit. If no standard solutions fit, feed into their ongoing evolution where appropriate.
- Fault finding and performance issues support to operational support teams, leveraging available tooling.
- Solution design impact assessment in terms of risk, capacity and cost impact, inc. estimation of project change and ongoing run costs.
- Development of the requisite architecture inputs required to comply with the banks governance processes, including design artefacts required for architecture, privacy, security and records management governance processes.
Vice President Expectations
- To contribute or set strategy, drive requirements and make recommendations for change. Plan resources, budgets, and policies; manage and maintain policies/ processes; deliver continuous improvements and escalate breaches of policies/procedures..
- If managing a team, they define jobs and responsibilities, planning for the department’s future needs and operations, counselling employees on performance and contributing to employee pay decisions/changes. They may also lead a number of specialists to influence the operations of a department, in alignment with strategic as well as tactical priorities, while balancing short and long term goals and ensuring that budgets and schedules meet corporate requirements..
- If the position has leadership responsibilities, People Leaders are expected to demonstrate a clear set of leadership behaviours to create an environment for colleagues to thrive and deliver to a consistently excellent standard. The four LEAD behaviours are: L – Listen and be authentic, E – Energise and inspire, A – Align across the enterprise, D – Develop others..
- OR for an individual contributor, they will be a subject matter expert within own discipline and will guide technical direction. They will lead collaborative, multi-year assignments and guide team members through structured assignments, identify the need for the inclusion of other areas of specialisation to complete assignments. They will train, guide and coach less experienced specialists and provide information affecting long term profits, organisational risks and strategic decisions..
- Advise key stakeholders, including functional leadership teams and senior management on functional and cross functional areas of impact and alignment.
- Manage and mitigate risks through assessment, in support of the control and governance agenda.
- Demonstrate leadership and accountability for managing risk and strengthening controls in relation to the work your team does.
- Demonstrate comprehensive understanding of the organisation functions to contribute to achieving the goals of the business.
- Collaborate with other areas of work, for business aligned support areas to keep up to speed with business activity and the business strategies.
- Create solutions based on sophisticated analytical thought comparing and selecting complex alternatives. In-depth analysis with interpretative thinking will be required to define problems and develop innovative solutions.
- Adopt and include the outcomes of extensive research in problem solving processes.
- Seek out, build and maintain trusting relationships and partnerships with internal and external stakeholders in order to accomplish key business objectives, using influencing and negotiating skills to achieve outcomes.
All colleagues will be expected to demonstrate the Barclays Values of Respect, Integrity, Service, Excellence and Stewardship – our moral compass, helping us do what we believe is right.
