- Include a brief portfolio or GitHub showcase that demonstrates clean, well‑tested code and CI/CD pipelines.
- During interviews, ask about Oportun’s incident‑response process to show your interest in production reliability.
- If salary isn’t disclosed, research typical senior staff engineer compensation for remote Mexican talent and be prepared to negotiate based on your experience.
- Watch for vague statements about “flexible hours” without clear expectations; ask how core collaboration windows are handled across time zones.
