Software engineers design, develop, and maintain the applications and systems that power modern businesses. Whether you need to build a custom web application, develop a mobile app, or scale an existing platform, hiring the right software engineer is essential for business success. This guide covers what software engineers do, typical costs, and how to find and hire top talent.
What does a software engineer do?
Software engineers build and maintain the applications, systems, and platforms that power today’s businesses. They write clean, efficient code, architect scalable solutions, and solve complex technical challenges. Unlike basic coding, software engineering involves a systematic approach that prioritizes reliability, maintainability, and long-term performance.
Day-to-day, software engineers analyze requirements, write and test code, debug issues, and collaborate with designers, product managers, and other developers. They work with programming languages like Python, JavaScript, Java, and C++, and use frameworks tailored to your project's needs. Their role extends beyond writing code to making architectural decisions that determine how an application handles data, security, and user traffic as the business grows.
Common projects include custom web and mobile application development, API development and third-party integrations, database design and optimization, system architecture planning, and legacy system modernization.

Step 1: Craft a targeted job post
The quality of your job post directly influences the caliber of candidates who apply. In your post:
Describe your project's purpose, key features, and desired outcomes
List technologies required, such as Python/Django backend with React frontend
Mention must-have skills like GraphQL API development, Docker containerization, or AWS cloud deployment
Cover logistics such as your budget range and deadline
To create a tailored job post quickly, try the Job Post Generator powered by Uma™, Upwork’s Mindful AI. Describe what you need in a few sentences, and Uma will craft a job post in seconds. You can also review software engineer job description templates for ideas and inspiration.
Step 2: Evaluate proposals
Taking a structured approach to reviewing proposals will help you move efficiently from a large applicant pool to a focused shortlist.
Have Uma give instant video interviews and side-by-side comparisons
Use Upwork’s filters to find candidates by rate, location, and experience
Review proposals for signs that the candidate has understood your job post and has the skills to meet your needs
Check profiles for links to active Github accounts and similar coding repositories, checking for coding quality and accuracy
Check portfolios for case studies showing how their previous work has accomplished their clients’ goals
Step 3: Interview your top choices
Quick video interviews give you the chance to ask any questions you have left for your top candidates, and to get a feel for what a collaboration with them might be like.
Schedule and conduct interviews within Upwork messaging to get instant transcripts and summaries from Uma
Ask the candidates to walk you through past work from their portfolio, focusing on aspects that are similar to your project and challenges they overcame
Walk through their workflow from requirements gathering to deployment
Discuss logistical details such as communication frequency, payment, and ownership of deliverables
You can refer to common interview questions for freelancers to help keep your conversations focused and productive.
Step 4: Agree on scope and begin work
Once you’ve found the right person, you can send a contract directly through the Upwork marketplace. A solid contract protects both parties and helps collaborations be successful from beginning to end.
Use Upwork's contract workroom, messaging, and payment protection for secure collaboration
Choose fixed-price contracts for projects with clear deliverables, such as implementing a single feature or configuring a single plugin
Break large projects into milestones, such as gathering requirements, planning, executing, testing, and deploying
Choose hourly contracts for ongoing work or projects without clear deliverables, such as ongoing code review, monitoring, and security patching
