Software Engineer (Java/Full Stack) | Contract-to-Perm | London
Location: Liverpool Street, London (Hybrid – 2-3 days onsite)
Rate: £550 per day (Inside IR35)
Type: Contract-to-Permanent
Start Date: Early to Mid-April 2026
The Opportunity
We are looking for a versatile Software Engineer to join a high-impact feature team within a major Strategic Transformation Programme. This is a mission-critical initiative focused on modernising core platforms, services, and operating models for a leading Financial Services institution.
This role is unique: it begins as a day-rate contract to support immediate delivery, with a guaranteed path toward a permanent position. It is the ideal move for a consultant looking for long-term stability or a permanent developer looking to "test-drive" a major modernisation project before committing.
The Role
As a Full Stack Engineer, you will design and improve software that delivers business-critical capabilities for both customers and internal colleagues. You will work closely with stakeholders—including Sales and Trading teams—to solve complex problems and contribute to the firm's growth.
Key Accountabilities:
-
Full Stack Development: Design and develop scalable backend services using Java (Spring Boot) and modern frontend components (Angular/React).
-
Cloud & DevOps: Deploy and maintain secure, performant code within AWS, implementing CI/CD pipelines with a test-first mindset.
-
Collaboration: Participate in Agile ceremonies, peer reviews, and cross-functional solution design.
-
Engineering Excellence: Promote code quality, security best practices, and knowledge sharing within internal tech communities.
Technical Requirements
-
Backend: Strong proficiency in Java 17+, Spring Boot, REST APIs, and Microservices.
-
Frontend: Experience with Angular(with an interest in React/TypeScript for future workstreams).
-
Data: Solid SQL skills (PostgreSQL, MSSQL) and exposure to NoSQL (MongoDB, Cassandra).
-
Infrastructure: Familiarity with AWS, Docker, Kubernetes, and Kafka.
-
Tooling: Hands-on experience with CI/CD tools like Jenkins, GitHub Actions, or GitLab CI.
-
Testing: Commitment to quality using JUnit, Mockito, and Test Containers.
The Interview Process
To facilitate an April start, we have a streamlined two-stage process:
-
Technical Assessment: An online challenge to demonstrate your coding and problem-solving logic.
-
Teams Interview: A final round on teams to meet the senior stakeholders to discuss the long-term roadmap and culture fit.
Why Apply?
-
Hybrid Flexibility: Enjoy the culture of a Liverpool Street hub with 2-3 days of remote flexibility.
-
High Impact: Work on a transformation project that is changing the face of the clients digital offering.
-
Career Security: Benefit from a competitive contract rate today with a seamless transition to a permanent career tomorrow.
