Developer Support Engineer - Remote Eligible

Developer Support Engineer

At interop.io, we empower the world's leading financial institutions to integrate and automate mission-critical applications across the enterprise desktop. To strengthen our Product Support team, we're looking for a Developer Support Engineer with strong technical skills — ideally someone with a software development background who wants to apply their expertise in a client-facing support role.

You'll be analyzing logs, debugging code, troubleshooting APIs, and collaborating directly with Engineering and Product to solve complex client problems. If you enjoy combining hands-on technical problem solving with real client impact, and you're looking for something beyond a call center role we would love to hear from you!

In This Role You Will:

Investigate and resolve complex client issues by analyzing logs, stack traces, APIs, and integration flows

Debug JavaScript/TypeScript in production-like scenarios; write small scripts/tests to reproduce client environments

Communicate with customers via ticketing system, or email

Initiate and participate in audio/video calls to deeply troubleshoot issues within the customer's environment

Collaborate closely with Product and Engineering teams to identify root causes and ensure smooth resolutions

Build diagnostic tools, scripts, and sample applications to streamline support and improve client outcomes

Contribute to our knowledge base and internal runbooks with developer-grade solutions and examples

Act as a trusted technical advisor, explaining issues and best practices to both technical and non-technical stakeholders

Participate in on-call rotation (shared across the team / approx. 1 week per month)

Your Profile:

Strong JavaScript / TypeScript literacy (read/debug production code; write small scripts/tests)

Proficient in log analysis (stack traces, errors, correlation across services)

API troubleshooting (REST/GraphQL; auth flows; headers; Postman/cURL)

Working knowledge of desktop/web fundamentals: Electron, iframes, browser contexts, CORS, storage

Practical understanding of environments/config management (dev/QA/stage/prod; feature flags; versioning)

Excellent written and verbal communication skills, with the ability to translate technical findings into client-friendly language

Desire to help customers and willingness to contribute to the team's success

Fluent in English – verbally & written

Availability to perform on-call duties

Nice to have:

QA/Automation or DevOps exposure (CI logs, releases, telemetry)

Scripting beyond JS (Python/Node CLI, .NET, Java) for quick internal tools

Experience with enterprise client support and secure data handling

Familiarity with Jira/JSM workflows and disciplined documentation

We Offer:

Competetive, market-leading salary

The freedom to work from home or the office

Performance bonuses

25 days off with up to 8 extra bonus days paid annual holiday

Premium healthcare and dental package.

Co-funded Multisport card

Food vouchers

Access to an employee Well-being program

Long-term employee value distribution scheme (LEVD)

Modern office space at Campus X, recreation zones, and a spacious rooftop terrace

Generous refer-a-friend program

Experienced, skilled and friendly teammates

Clear career path and continuous learning opportunities.
