The Opportunity
We’re recruiting for a Senior Software Engineer with deep experience in UniVerse/UniData and UniBasic (Pick BASIC) to join a technology-led organisation modernising a long-established, high-volume transactional platform.
This isn’t a "keep the lights on" role. It’s for someone who enjoys taking mature systems and making them faster, safer, easier to deploy, and easier to integrate, without losing the reliability the platform is known for.
If you can bridge classic U2/Pick engineering with modern delivery (APIs, testing, automation, observability), this is a standout opportunity.
What you’ll be doing
You’ll work end-to-end across feature delivery, platform improvement, and technical leadership.
Core responsibilities
Design, build and support enhancements in UniBasic (Pick BASIC) within UniVerse/UniData environments
Drive modernisation: refactoring legacy routines, reducing tight coupling, introducing clearer module boundaries and reusable services
Build and maintain RESTful APIs (service wrappers, request/response mapping, validation, error handling, idempotency)
Strengthen quality: unit testing, integration testing, regression approaches, test data strategies, and automated checks
Troubleshoot and tune performance: UniQuery, U2 SQL, indexing strategy, batch processing, caching, concurrency/locking and I/O hotspots
Improve delivery discipline: code reviews, standards, documentation (e.g. ADRs), release checklists, operational runbooks
Mentor and uplift the team: good engineering habits, pragmatic architecture, and clean, maintainable code
Tech stack (what you’ll be working with)
This role sits across the core platform and modern integration tooling.
Essential skills
UniBasic (Pick BASIC)
UniVerse or UniData
UniQuery and/or U2 SQL
SQL fundamentals (joins, aggregation, performance thinking)
Linux (shell basics, logs, permissions, processes, scheduling)
REST APIs (HTTP semantics, auth patterns, versioning, contract-first thinking)
Strong grasp of design patterns, SOLID, and dependency injection concepts (even when implemented pragmatically)
Highly desirable
CI/CD pipelines (build automation, gated deployments, release confidence)
Docker / containerisation
Cloud exposure: AWS or Azure
C# / .NET for integration services and tooling
Front-end awareness: HTML5 / Angular (useful, not essential)
What success looks like (first 3-6 months)
You’ll become a go-to engineer for U2/Pick design decisions and root-cause analysis
You’ll ship meaningful features while improving delivery confidence (testing + automation)
You’ll standardise patterns for exposing UniVerse/UniData capability via versioned APIs
You’ll reduce risk in fragile areas: inconsistent error handling, undocumented flows, manual release steps
What we’re looking for
Strong commercial experience as a Software Engineer (typically 6+ years)
Proven background in UniVerse / UniData / UniBasic in production environments
Comfortable owning technical direction and making trade-offs that protect stability and enable change
Clear communicator who can lead technical conversations and bring others with you
