A senior engineering position responsible for building and maintaining integration services connecting enterprise platforms and external systems. The role covers architecture, implementation, testing, deployment, and operational support.
Highlights
Work on complex integration systems with ownership across the software lifecycle, collaboration with external partners, and opportunities to solve challenging technical problems.
Description
The Company
Finalto is a global provider in the over-the-counter trading space, offering brokerages and institutional clients our cutting-edge trading platform—ClearVision.
With liquidity from Tier 1 banks, ClearVision ensures superior pricing and execution quality.
Our R&D hub in Copenhagen drives continuous innovation and top-tier application performance.
The Job
As a Senior Software Engineer in the Integrations Team, you will participate in the full SDLC from analysis and design through implementation, testing, release, and production support.
You will independently own integration work and help develop and maintain services connecting ClearVision with clients, Tier 1 banks, liquidity providers, and trading venues.
You will work directly with third parties to clarify behaviour, coordinate testing and investigation, and drive joint issues to resolution.
ClearVision is built on proprietary frameworks and established engineering patterns.
We do not expect you to know them before joining; every engineer goes through a learning period.
What matters is your ability to understand unfamiliar systems, structure ambiguous work, design robust components, and make sound decisions.
This is a senior individual-contributor role, not a Technical Lead or domain-lead position.
Deliverables must meet high standards of correctness, latency, performance, and reliability.
Qualifications
We are looking for a Senior Software Engineer with the skills and capabilities to match:
· Degree in computer science or software engineering, or equivalent experience
· 5+ years of professional software development experience, including:
o production software in C#/.NET or a comparable object-oriented language
o concurrent, event-driven, or distributed systems
o automated testing and tools such as Git, Visual Studio, MSBuild, and NUnit
· Ability to structure ambiguous work, make sound trade-offs, and design maintainable components.
· Experience owning third-party integrations and managing external technical stakeholders through joint problem solving.
· FIX or electronic-trading experience is a plus, not a requirement.
· Strong knowledge of OOP, SOLID, data structures, algorithms, network protocols, testing, observability, and production reliability.
Who You Are
You are analytical, structured, and comfortable taking independent ownership without being the formal lead.
You communicate clearly, engage internal and external stakeholders in shared problem solving, and keep work moving across organisational boundaries.
You care about clean, maintainable code, production reliability, and pragmatic engineering decisions.
The Workplace
You will be working in our office at Amerikakaj, Copenhagen.
Onsite work is mandatory for a minimum of 60% to secure cooperation and coherence within the team.
