About the role
Technical Support Engineer Endex builds AI agents that handle complex, end-to-end work for the world's most demanding teams. Today we're deployed across leading financial institutions and Fortune 500 companies, embedded in the tools and workflows they rely on. We operate at the frontier of agentic knowledge work, partnering closely with top AI research labs and backed by the OpenAI Startup Fund. We're on a mission to build the most capable digital coworker in the world. We're looking for someone who can reproduce a difficult product issue and work methodically toward a resolution. As a Technical Support Engineer at Endex, you'll own technical investigations across support requests. You'll work with engineering on bugs and operational issues while giving customer-facing teams the context to communicate accurately.
Your key responsibilities include:
Diagnose production issues: Use logs, request traces, API responses and reproducible examples to isolate failures across the product and integrations.
Drive technical resolution: Validate workarounds, coordinate engineering fixes and confirm that the customer's workflow works again.
Resolve what you can: Apply supported fixes and validate the result with the customer team.
Support incident response: Provide technical context and timely investigation updates.
Prevent repeated incidents: Write runbooks and root-cause summaries, improve diagnostic tooling and bring recurring defects back to product engineering.
What we're looking for:
Technical support experience: You've investigated production software issues or equivalent engineering problems.
Debugging ability: You can reason through logs, API behavior and system dependencies.
Coding fundamentals: You can read code and build small tools or reproductions.
Clear documentation: You leave investigation notes another engineer can act on. Hands-on troubleshooter: You can investigate authentication, permissions, networking and data-flow problems, and communicate findings to users and engineers.
Nice to have:
- Cloud application support
- Python or JavaScript experience
- Experience with SQL, HTTP APIs and Python or JavaScript for support investigation
- Full-time benefits include: Health & dental insurance
- Monthly wellness stipend 401K matching
Before you apply
Applying takes about a minute. These four things decide how fast it moves after that.
Your profile is current
It's what we read first. Occupations, seniority and locations matter more than a long history.
Two examples you can talk through
Not a portfolio — just two pieces of work where you can explain the decisions and what you'd change.
A number in mind
What you're on now and what would make you move. We negotiate better when we know both.
Your notice period
Employers plan around it, and it's the question that stalls offers most often.
Once you apply, someone reads it and calls you before anything reaches the employer — usually within two working days.
