About The Position

Soutron Global is looking for a Senior Software Engineer to be a key technical contributor on MINISIS — a 40+ year-old hybrid object/relational database and collection-management platform serving museums, archives, libraries, and government institutions worldwide. This is a rare opportunity to go deep on a complex, mission-critical cultural heritage platform and help shape its modernization while keeping a battle-tested core stable and production-ready.
You will report to the Director of Engineering and serve as a senior individual contributor and technical area owner across MINISIS — contributing to the stability of the existing C/C++ engine, the architecture of the new backend and API layer, and the progressive migration of desktop functionality into CAMS Online, Soutron's modern web application. You will work closely with the front-end development team daily and benefit from a structured onboarding program into the platform and its architecture.
This is not a greenfield role. The right candidate is energized by going deep on a complex, long-lived system and modernizing it methodically — not someone who wants to discard decades of battle-tested logic.

Requirements

• C/C++ (Windows) (essential) — 6+ years of production C/C++ development on Windows (Win32/Win64, multithreading, memory-mapped files); experience contributing to or maintaining custom in-house database or storage engines
• Modern full-stack development (essential) — strong Node.js/TypeScript skills; proven experience shipping public-facing REST or GraphQL APIs
• Document databases — hands-on experience with document-oriented or NoSQL databases (MongoDB, Couchbase, Elasticsearch, or similar)
• Legacy modernization — demonstrated success migrating legacy desktop applications to modern web architectures; comfort reverse-engineering large, mature, sparsely documented codebases
• Large-scale migrations — proven experience delivering major platform migrations, including tooling, data migration, and customer transition planning
• Agile Scrum — proven experience working within an established Agile Scrum methodology; comfortable with sprint planning, standups, story pointing, and sprint reviews
• SDLC practices — experience working within a formal software development lifecycle including code review, branching strategy, CI/CD pipelines, and QA gates
• Communication and collaboration — excellent written and verbal communication; comfortable working daily alongside front-end developers and with non-technical stakeholders; able to produce clear technical documentation

Nice To Haves

• Prior work on museum, archive, library, or collection-management systems
• Familiarity with CDS/ISIS, InMagic, Cuadra STAR, Adlib, EMu, or similar heritage platforms
• Experience migrating ISAM/B-tree engines to NoSQL or hybrid models
• Large 32-to-64-bit migrations in legacy C++
• GraphQL API design and implementation
• Atlassian suite — Bitbucket, Jira, Confluence
• Containerization — Docker, Kubernetes (for future infrastructure evolution)

Responsibilities

• Codebase ownership — senior developer and technical area owner for the MINISIS C/C++ engine, middleware, and associated components, working alongside the Director of Engineering on architecture decisions
• Platform stability — keeping the existing codebase stable, fully 64-bit capable, and production-ready throughout the modernization transition
• Backend modernization — designing and building the new document-oriented backend (Postgres, Couchbase, or similar) and REST/GraphQL API layer
• Desktop-to-web migration — leading the port of desktop functionality into CAMS Online; architecting a seamless customer migration path
• Front-end partnership — working daily with the front-end team on architecture, data models, API contracts, and feature delivery for CAMS Online
• Migration tooling — creating robust, well-tested migration tools and processes for customer transitions
• Engineering process adoption — adopting Soutron's established SDLC, Agile Scrum methodology, and code review practices
• Documentation — producing clear architecture, API, and migration path documentation for a historically sparsely documented codebase

Benefits

• Competitive salary benchmarked to your market and experience.
• Fully remote working with flexible hours.
• Generous paid time off and public holiday allowance.
• Budget for learning, conferences, books, and equipment.
• Meaningful work on a product that real customers rely on every day.
• The chance to help shape the engineering culture of a growing, investor-backed business.
