Software Development Engineer in Test - Electronic Trading

A specialist financial technology firm operating in electronic fixed income trading is looking for a Software Development Engineer in Test to join a team of senior engineers building and maintaining critical trading infrastructure. The team is small, highly experienced, and moves with precision. This is a role for someone who takes genuine pride in software quality and wants to own it end to end.

🟢 The Role

You'll work embedded in the development team, expanding and improving automated acceptance and end-to-end test coverage, contributing to exploratory testing, and supporting the continuous delivery pipeline. You'll collaborate closely with developers and business analysts, pair on problems, and proactively identify where quality improvements are needed. This is not a checkbox QA role. It's a hands-on engineering position for someone who thinks critically, breaks things deliberately, and cares about getting it right.

🟢 Main Responsibilities

Expand and maintain automated acceptance and end-to-end test suites
Challenge and enrich requirements from a test coverage perspective
Identify gaps in quality and proactively drive improvements
Support the development team by enhancing testing infrastructure for continuous delivery
Participate in pair programming and collaborative problem solving
Contribute to exploratory testing across complex distributed systems

🟢 Key Requirements

Solid experience with Object Oriented Programming — Java strongly preferred
Hands-on experience with both component-level and end-to-end testing
Experience testing failure scenarios and edge cases, not just happy paths
Comfortable working as part of a development team, not in a siloed QA function
Strong communicator — equally at ease with technical and non-technical stakeholders
A GitHub profile or equivalent evidence of your programming work

🟢 Bonus Points

Experience with continuous delivery pipelines or CI environment management
Exposure to API testing (non-HTTP), distributed systems, or event-driven architectures
Familiarity with messaging or network protocols
Background in electronic trading or financial systems — fixed income a plus
Experience with Extreme Programming or pair programming practices

🟢 Company Offer

Salary up to €100,000 depending on experience
Equity / share scheme
