Contract Software Engineer (Integrations + Front-end) at Travefy

Our stack

• Back end: C# and .NET on AWS.
• Front end: React and Ember.js.
• Integrations: REST and JSON APIs, OAuth 2.0, and webhooks.

Required skills

• Integrations: proven track record building production integrations with REST and JSON APIs, OAuth 2.0, and webhooks, including error handling, retries, and idempotency.
• Front end: strong React, and a willingness to work in Ember.js, enough to build the UI that surfaces your integrations and to deliver contained dashboards and reporting views (Ember experience is a plus but you can ramp into it).
• Back end: solid C# and .NET, building and consuming production APIs.
• Testing discipline: automated tests covering both happy path and failure modes.
• Clear written English: communicates progress and blockers proactively and works well async.

What winning in this role looks like

• You ship tightly scoped projects that meet their acceptance criteria, fully tested and review ready.
• Your integrations handle the messy cases gracefully, with sensible retries, idempotency, and error handling.
• Your written updates make it easy for the team lead to know exactly where things stand.
• You leave the codebase and docs a little better than you found them.
• The team trusts you to take a problem and run with it.
