Senior Software Engineer

Senior Software Engineer Soutron | Fully Remote | Full-time



 

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 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 Have (Not Required)

• 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)

How We Work

• Remote-first. The team is fully distributed. We default to async, keep meetings purposeful, and trust people to manage their own time.
• Small team, real ownership. You won't be lost in a layer of process. Your work ships, and you get credit for it.
• Pragmatic, not dogmatic. We pick tools and patterns that fit the problem. We're modernizing — but we respect the systems our customers depend on today.
• Learning is part of the job. We set aside time for reading, experimentation, and genuine skill growth, not just shipping.

What We Offer

• 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.

How to Apply

Send us your CV along with a short note — a paragraph is fine — about a project you're proud of and why this role is interesting to you. A polished cover letter is not required; we care about clear thinking, not formatting.
We'd rather hear from you and decide together than have you disqualify yourself. If you meet most of the "What You'll Bring" section and the role sounds like you, please apply.
