Be ready to go over:

• Working with Designers and Copywriters – How you coordinate with creative teams to integrate design assets, handle copy changes, and ensure UI consistency.
• Translating Business Logic – Your method for converting high-level product requirements into concrete technical specifications and development tasks.
• Feedback Loops – How you handle changes in project scope or design assets midway through a development cycle.

Example scenarios:

• Discussing how you would handle a situation where a graphic designer's asset does not fit the responsive layout of a web application.
• Describing your approach to clarifying ambiguous requirements with a product manager before starting to write code.

Software Quality & SDLC Best Practices

This area focuses on your understanding of the broader software engineering lifecycle, code health, and engineering discipline.

Be ready to go over:

• Code Reviews – How you conduct thoughtful code reviews, give constructive feedback, and receive critiques of your own code.
• Estimation and Risk Management – Your framework for estimating development tasks and communicating timeline risks to stakeholders.
• Diagnostics and Debugging – Your systematic approach to identifying, reproducing, and resolving production bugs.

Example scenarios:

• Explaining how you would communicate to a project manager that a critical integration bug will delay a planned release by two days.
• Walkthrough of a time you successfully refactored a brittle piece of code to improve system stability and performance.

As a Software Engineer at Peerfit, your day-to-day work centers on building reliable solutions that support our wellness network. You will study information needs, analyze system requirements, and develop applications that integrate seamlessly with existing systems. Writing clean, maintainable, and well-documented code is a core expectation, and you will actively contribute to the team's shared codebase through regular software release cycles.

A significant portion of your role involves cross-department collaboration. You will work closely with product managers, copywriters, graphic designers, and QA teams to clarify requirements and translate business goals into technical specifications. You are expected to write and maintain technical design documents and clear software instructions, ensuring that the entire team remains aligned on product architecture and implementation details.

Additionally, you will play an active role in maintaining system health and operational excellence. This includes developing tools to test software, monitoring system data, and diagnosing and resolving software issues quickly and efficiently. You will also participate in code reviews, giving and receiving thoughtful feedback to consistently apply generally accepted best programming practices and improve the overall software development life cycle.

To be successful in this role, you should possess a strong foundation in modern software engineering practices, combined with a collaborative and proactive mindset.

• Must-have skills – Strong proficiency in object-oriented programming, experience building and integrating with web APIs, and a solid understanding of unit and integration testing frameworks.
• Must-have skills – Proven experience working in an agile environment, including a track record of estimating project work and communicating development risks effectively.
• Must-have skills – Exceptional communication skills, with the ability to collaborate with non-technical team members such as graphic designers, copywriters, and project managers.
• Nice-to-have skills – Experience with digital health or wellness platforms, familiarity with cloud infrastructure, and a history of contributing to open-source projects or improving engineering SDLC processes.

Q: What is the technical interview style like at Peerfit? A: The technical interviews focus on practical coding and system design rather than theoretical whiteboard puzzles. You can expect a take-home coding challenge (such as modeling a card game) followed by a live, collaborative coding session where you work with engineers to expand or discuss your code.

Q: How does the team handle project estimation and deadlines? A: Peerfit values realistic planning and transparent communication. Engineers are expected to estimate their own work and proactively communicate any timeline risks or resource constraints to project managers before deadlines are impacted.

Q: What is the engineering team's culture like? A: The team is collaborative, highly communicative, and supportive. There is a strong emphasis on continuous learning, giving and receiving constructive feedback during code reviews, and maintaining a healthy work-life balance.

Q: How can I protect myself from online recruitment scams targeting Peerfit applicants? A: Always ensure that any recruiter reaching out to you is using an official @peerfit.com email address. Peerfit will never conduct interviews entirely via email, send automated behavioral questionnaires instead of conducting a live call, or ask for your physical address during the initial stages of the interview process.

• Structure your code for readability: During the take-home and live coding assessments, prioritize clean, readable code over clever, highly compressed syntax. Use descriptive variable names and organize your logic in a way that is easy for another engineer to follow.
• Emphasize your collaboration experience: Be ready to share concrete examples of how you have worked with designers, copywriters, and product managers in the past. Highlight how you handle differing opinions and align on technical solutions.
• Explain your thought process out loud: During the live coding sessions, talk through your decisions, trade-offs, and assumptions. This helps interviewers understand how you approach problem-solving and how you handle unexpected challenges.

• Proactively discuss risk management: When answering behavioral questions, highlight your ability to identify technical debt, estimate work accurately, and raise flags early when a project timeline is in jeopardy.

The Software Engineer position at Peerfit offers an exciting opportunity to build impactful software that helps users lead healthier lives. By focusing your preparation on practical coding logic, system integration, and cross-functional collaboration, you can demonstrate both the technical capability and the collaborative mindset that the team values.

As you prepare, make sure to practice modeling complex logic cleanly, refine your testing strategies, and prepare stories that showcase your ability to work alongside creative and product teams. Structured preparation will give you the confidence to excel in both the technical challenges and the behavioral conversations.
