About Soutron

Soutron builds specialist information, library, and archive management software used by corporate, legal, government, and research organizations around the world. Our platform helps teams curate, discover, and unlock the value of their most important knowledge assets — from legal precedent libraries to corporate archives to specialist research collections.
We are a small, focused team that ships modern SaaS for a sector that has historically been under-served by technology. With new investment behind the business, we are modernizing the platform, expanding the product, and investing in the engineering team that will carry us into the next decade.

About the Role

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.

What You'll Do

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

What You'll Bring

These are the core skills we're looking for. You don't need deep expertise in every item — if you're strong in most of them and motivated to grow in the rest, we want to talk.

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 applicati
