Software Development Engineer

This role starts as an intensive training program before converting into a full Software Development Engineer position, aimed at programmers who already know at least one language well but haven't yet worked in a professional engineering team. Over 12 to 13 weeks, you'll go through structured technical training designed to close the gap between writing code for coursework or personal projects and shipping production software as part of a team. Completing the program successfully is what earns you the SDE title, so this isn't a guaranteed placement, it's a proving ground. Once in the role, you'll work across the stack, building web and mobile features in JavaScript, Python, Java, HTML, and CSS, while also owning the less glamorous parts of the job: writing documentation, supporting production issues, and pushing hot fixes when something breaks. Deployments are expected to be close to defect-free, so there's real pressure to test and debug thoroughly rather than move fast and break things. This role suits self-motivated engineers who pick up new tools quickly and communicate clearly, since MountBlue places people into partner startups where they'll work directly with CTOs and engineering leaders. It's a weaker fit for anyone who wants a slow, highly structured onboarding, since the pace here is fast from day one. For strong performers, this becomes an unusually direct path into startup engineering roles with real technical ownership early in their career.
