Role Description We're a small, fast-moving software team building web platforms and the desktop tooling that goes with them. We're growing a dedicated platform team and looking for a versatile Python engineer who's happy owning a feature end to end — from a backend API down to the client that consumes it. You'll work across a server-rendered web application and a cross-platform desktop application, integrating third-party services, handling sensitive data carefully, and shipping reliably. What You'll Do - Build and maintain backend services and REST APIs in Python / Django. - Model and evolve relational data, write migrations, and keep the data layer clean. - Extend a cross-platform desktop application built in Python. - Integrate third-party APIs, webhooks, and OAuth / service-account auth flows. - Handle authentication, encryption of sensitive data, and secret management thoughtfully. - Own the full lifecycle: tests, containerized builds, CI/CD, and deployments. - Write clean, tested code and review your teammates' work. Qualifications - 3+ years of professional Python, with real production experience in Django (or a comparable web framework). - Solid relational database skills (PostgreSQL or similar) — modeling, querying, migrations. - Comfortable with Docker and modern CI/CD workflows. - Experience integrating third-party APIs, webhooks, and auth flows. - A good grasp of authentication and security fundamentals — tokens, encryption, secret management. - Strong testing habits and confident with Git-based collaboration. Requirements - You take ownership. You're comfortable picking up an ambiguous problem and driving it to a shipped result without a lot of hand-holding. - You communicate clearly and write things down — async-friendly and remote-ready. - You care about getting the details right, especially around security and data handling. - You're pragmatic: you reach for the simplest solution that works before reaching for a complex one. - You enjoy working across the stack and aren't precious about which layer a problem lives in. - You're a fast learner who's energized by a small team where your work has visible impact. Benefits - Competitive salary package. - Compensation paid in USD. - Fully remote role with the flexibility to work from anywhere. - Company-wide events and team gatherings are planned to foster collaboration and connection. Company Description Our stack includes Python, Django, PostgreSQL, Celery, Redis, Docker, AWS, and pytest.

• Work closely with the rest of the engineering team to deliver solutions ranging from small-scale client assistance to stack-spanning alterations that enable huge new features. • Work with the support and operations teams to understand large client problems from first principles and propose new solutions. • Gain a holistic understanding of the Lessonspace stack, infrastructure and internal development environment, as well as how our customers use us, with an eye to becoming a potent source of internal systems knowledge for other engineers and teams to depend on. • Be able to take full ownership of your feature releases, testing and reliability, ultimately delivering major releases with confidence and minimal assistance. • You will be working at the nexus of engineering, sales and operations and may be engaged to deliver specific features to help larger customers onboard smoothly onto our platform.
