What is a Software Engineer at Athelas?

As a Software Engineer at Athelas, you are at the forefront of building robust, scalable systems that directly impact our users and business operations. Your role goes beyond simply writing code; you are an architect of practical solutions in a fast-paced, high-growth environment. You will be responsible for developing end-to-end features, integrating complex external APIs, and ensuring our infrastructure can handle rapid scaling.

The impact of this position is immediate and highly visible. You will contribute to core product lines, working on everything from backend data pipelines to frontend user interfaces. Because our teams move quickly, the software you build will often go from concept to production in a matter of days, directly influencing how users interact with our platform and how efficiently our internal operations run.

What makes this role uniquely challenging and interesting is the emphasis on practical engineering velocity. We do not focus on theoretical puzzles; instead, we value engineers who can take a basic CRUD architecture, integrate it with messy real-world data sources, and scale it effectively. You will be expected to make pragmatic architectural decisions, collaborate closely with cross-functional teams, and maintain a high bar for code quality while moving at startup speed.

Common Interview Questions

Getting Ready for Your Interviews

Preparing for an interview at Athelas requires a shift in mindset from traditional algorithmic interviewing to practical, hands-on software development. You should approach your preparation by focusing on building real applications, reading technical documentation, and communicating your design choices clearly.

We evaluate candidates across several key criteria:

Practical Coding and API Integration At Athelas, we rely heavily on connecting disparate systems. Interviewers will evaluate your ability to quickly read external documentation, construct API queries, and parse complex JSON responses. You can demonstrate strength here by writing clean, modular code that handles edge cases gracefully and extracts exactly the data needed.

System Architecture and Scalability As our user base grows, so must our infrastructure. We assess your ability to design full-stack applications from the ground up. Strong candidates will confidently discuss how to structure a basic CRUD application, choose the right database schemas, and outline strategies for scaling backend services when traffic spikes.

Product Pragmatism and Execution We value engineers who can deliver working software quickly without over-engineering. Your interviewers will look for your ability to take a high-level prompt, ask clarifying questions to narrow the scope, and implement a functional solution. Showing that you can balance speed with maintainability is critical.

Communication and Collaboration Building software is a team effort. We evaluate how well you articulate your thought process, respond to feedback, and clarify ambiguous requirements. You will succeed by treating your technical interviews as collaborative working sessions rather than solitary exams.

Interview Process Overview

The interview process for a Software Engineer at Athelas is designed to be highly practical, moving quickly from initial introductions to hands-on technical evaluations. You will begin with a recruiter screen focused on your background, location preferences, and general alignment with the role. This is often followed by a deeper conversational interview with a hiring manager or a member of the sales engineering team, where you will discuss your past projects and behavioral scenarios.

The core of the evaluation takes place during the technical rounds. Rather than abstract whiteboard problems, you will face real-world scenarios. Expect a focused technical screen where you will be asked to query an API and parse its data using Python. If successful, you will move to a virtual onsite consisting of multiple sessions: a full-stack application build, a system design discussion focused on scaling, and a final alignment call with engineering leadership, often the CTO.

We pride ourselves on a process that mirrors the actual day-to-day work at Athelas. We want to see how you read documentation, write functional code, and communicate when hitting roadblocks.
