About the role

As a Backend Engineer, you will propose, specify, implement, maintain and decommission code that powers Todoist for millions of active users through our diverse portfolio of apps and integrations.
Contributing to an architectural revamp, ensuring flawless cross-device sync, and seamless sharing are some current opportunities where you can have a large impact.
Our codebase is far from perfect. An in-house Python framework that resembles Flask and circular dependencies are challenges representative of our codebase. We are working hard to modernize our stack and architecture, and build a backend that is rock-solid running on AWS and fun to work with.
While Python is our main language today, we aim to reduce barriers across teams and stacks, and expect engineers to be comfortable reaching beyond language or framework boundaries when needed.
We’re a great fit if you are independent and driven, thrive in understanding and evolving legacy systems, maintaining a high delivery cadence and quality, systematically repaying technical debt, mentoring colleagues, and working with a highly resilient team.
We are looking for an engineer who will raise the bar for the team and help us continue evolving our momentum, solution architecture, and overall quality.
Being a Backend Engineer is not just about churning out code. You get to lead projects right from their inception, work with our talented leadership (filled with engineers-at-heart who understand the value of refactoring), and collaborate with adjacent teams to solve pain points our users face.

Requirements

You have substantive professional experience with developing web services and understand the moving parts (DNS, HTTP, DBs, etc.). You have designed, built, and maintained projects and features that have been deployed to production.
You are familiar with Python, know both its strengths (and how to capitalize on them) and weak points (and how to work around them), and you’re able to argue about them. You follow the evolution of the Python ecosystem. You’ve also used at least one other programming language professionally, and you are open to crossing boundaries between stacks when the work demands it
You are familiar with OWASP Top 10 web app security risks and know how to avoid and mitigate them. You can assess the security implications of a pull request or an architectural decision.
You are familiar with MySQL or PostgreSQL and have experience with their core concepts and subtleties. You care about and understand the performance impact of SQL queries you (or your code) writes, and have experience assessing and optimizing their performance.
You feel at home in the Unix shell. You are familiar with grep, and sed or awk. You often write bash or Python scripts to automate your work.
You’ve written tests long enough to have a taste for what a good test looks like, are aware of current testing practices, and can argue about each approach’s merits.
You understand the value and cost of abstraction, are versed in current architectural practices, and judiciously apply programming principles like SOLID, DRY, YAGNI, etc.
You thrive in a feedback-forward environment and actively contribute to our culture of sharing constructive input quickly and effectively. You're comfortable both giving and receiving direct feedback as a tool for continuous improvement and team excellence.
You yearn to be more than a mere executor, look for ways to inform the overall direction of the products you work on, and actively participate in sketching an implementation plan that focuses on value delivery with a well-derisked approach.
You are curious about how AI can improve both developer workflows and product features, and you are eager to adopt it competently and responsibly.
