Preparation at Alta Planning + Design requires a balance of hard technical skills and an ability to articulate how your work serves the broader goals of urban planning.

Technical Proficiency – You must be comfortable with the specific tools mentioned in our projects, particularly Vue.js and mapping libraries. Interviewers will look for your ability to write clean, maintainable code that accounts for real-world user needs like accessibility.

Problem-Solving Approach – We value engineers who can break down complex spatial problems into manageable technical tasks. Be ready to explain your logic during the take-home coding challenge, as this is a primary indicator of how you approach architectural decisions.

Interpersonal Collaboration – Since you will work closely with urban planners and project teams, your ability to communicate clearly is critical. Demonstrate that you can handle conflict professionally and work effectively with team members who have different areas of expertise.

The interview process at Alta Planning + Design is designed to evaluate both your technical competency and your alignment with our project-driven environment. You can expect a structured progression that begins with a recruiter screen to establish your baseline experience, followed by a practical demonstration of your skills.

The process is generally rigorous regarding technical application, often involving a take-home coding challenge that mimics the type of work you will do daily. Following the technical review, you will meet with both engineering and business stakeholders to ensure a cross-functional fit. We value candidates who show a genuine interest in the intersection of technology and urban infrastructure.

This timeline outlines the typical path from initial screening to a final hiring decision. Candidates should view the take-home challenge as their most significant opportunity to showcase their coding standards, while the subsequent interviews are your chance to demonstrate soft skills and cultural alignment.

Technical Execution and Coding Standards

You will be evaluated on your ability to produce high-quality, accessible, and performant code. For the take-home challenge, focus on code structure, readability, and the effective use of Vue.js and GIS integration.

Be ready to go over:

• Component Architecture – How you modularize your code for reusability.
• Data Handling – Your experience parsing and rendering GIS data efficiently.

As a Software Engineer, your day-to-day work centers on building and maintaining the digital tools that power our planning projects. You will spend significant time working with Vue.js to build dynamic, interactive interfaces that visualize complex urban data.

You will collaborate closely with planners and engineers to ensure that the data being displayed—whether it relates to traffic flow, public transit, or infrastructure—is both accurate and accessible to the public. You are expected to be a proactive problem solver, taking ownership of features from initial requirements through to deployment, while ensuring that the end product meets the high standards of performance and usability expected at Alta Planning + Design.

A strong candidate for this position combines technical depth with a pragmatic approach to development.

• Must-have skills: Proficient in Vue.js, experience with mapping libraries like Leaflet, and a solid understanding of GIS data principles.
• Nice-to-have skills: Experience with AutoCAD or Civil 3D is often beneficial given the nature of our firm's work, as is a background in civic technology or urban planning.
• Soft skills: Excellent communication, a collaborative mindset, and the ability to work in a high-turnover, fast-paced environment.

Q: How much time should I set aside for the take-home coding challenge? A: Plan to spend a few dedicated hours. The challenge is designed to test your ability to work with specific libraries, so ensure your environment is set up and you have reviewed the documentation for the tools provided.

Q: What is the company culture like? A: Alta Planning + Design is a project-focused, mission-driven organization. We value technical expertise that directly contributes to better urban environments, and we appreciate candidates who are vocal and proactive in team settings.

Q: Is there a specific emphasis on GIS? A: Yes. Because our work revolves around urban planning, the ability to handle and visualize spatial data is a significant differentiator.

Q: What is the typical timeline for the hiring process? A: From the initial phone screen to the final reference check, the process typically takes a few weeks, depending on the availability of the technical and business teams.

• Review the Stack: Ensure you are comfortable with Vue.js and Leaflet before the interview.
• Focus on Accessibility: Always mention how your code serves all users, including those with disabilities.
• Prepare for Behavioral Questions: Use the STAR method (Situation, Task, Action, Result) to frame your answers about past team challenges.
• Ask Thoughtful Questions: Use your time at the end of the interview to ask about current projects or team structure.

The role of Software Engineer at Alta Planning + Design offers a unique opportunity to build technology that shapes the future of our communities. By mastering the technical requirements and demonstrating a collaborative spirit, you position yourself as a strong candidate for this impactful position.
