Mid-Level Software Engineer Resume Example
Mid-level software engineers get hired when they prove ownership of system performance and efficiency, not by listing features without explaining technical decisions.
This resume is for mid-level software engineers who own end-to-end features or backend services, but aren't yet responsible for organization-wide technical strategy.
- Ownership of full-stack features or backend services
- Evidence of performance optimization and cost-efficiency gains
- Active participation in code quality and peer mentorship
- Experience section prioritizing technical outcomes over task lists
- Skills categorized by language, framework, and infrastructure
- Education and location details positioned for quick verification
Rohan Reddy
Summary
Experience
- Engineered a Java-based connector framework that standardized data ingestion for 12 external APIs, reducing the engineering time required for new integrations by 35%.
- Optimized PostgreSQL query performance for the configuration database, resulting in a 28% reduction in API response latency for 45,000 active users.
- Mentored 2 junior engineers on backend architecture best practices and established a standardized documentation process for the data platform team.
- Scaled the internal monitoring dashboard using React and TypeScript, enabling real-time tracking of 800+ concurrent sync jobs and improving incident response times.
- Developed and deployed 8 core UI components for the merchant analytics dashboard using React, increasing frontend unit test coverage from 65% to 88%.
- Refined the data export service using Node.js, cutting cloud infrastructure costs by $32,000 annually through more efficient memory management and batch processing.
- Launched a self-service onboarding flow that automated account provisioning for new enterprise clients, reducing manual support tickets by 42%.

What makes this resume effective
- This resume meets the hiring bar for mid software engineers by demonstrating end-to-end framework engineering, database performance optimization, and informal leadership through mentorship.
- At Airbyte, Rohan's work on the Java-based connector framework shows architectural ownership that directly reduced engineering overhead by 35%.
- The transition from Amplitude to Airbyte highlights a clear progression from building UI components to scaling high-concurrency backend systems.
How to write better bullet points
Helped build a new dashboard for internal users using React.
Scaled the internal monitoring dashboard using React and TypeScript to track 800+ concurrent sync jobs, improving incident response times.
It specifies the scale of the system and the direct impact on operational efficiency rather than just listing a task.
Wrote Java code for API integrations.
Engineered a Java-based connector framework that standardized data ingestion for 12 external APIs, reducing integration time by 35%.
It demonstrates the creation of a reusable system that improved team productivity instead of simple feature development.
Fixed slow database queries to make the app faster.
Optimized PostgreSQL query performance for the configuration database, resulting in a 28% reduction in API response latency for 45,000 users.
It provides concrete metrics and user scale to prove the significance of the technical optimization.
Mid-Level Software Engineer resume writing tips
- Quantify how your code improved system performance or reduced operational costs, like the 28% latency reduction achieved at Airbyte.
- Highlight instances where you standardized workflows or frameworks for other developers, such as the connector framework that saved 35% engineering time.
- List specific technologies used within each bullet point to prove hands-on proficiency with Node.js, PostgreSQL, and React.
Common mistakes
- Focusing only on 'implemented X feature' without explaining the technical complexity or the 'why' behind the decision.
- Omitting evidence of mentorship or code review contributions, which are critical signals for moving toward senior roles.
- Listing every technology ever touched rather than focusing on the stack relevant to the target role's core responsibilities.
Frequently asked questions
Is this resume right for someone with 3 to 5 years of experience? Yes, if you have transitioned from executing tasks to owning services rather than working exclusively under the direct supervision of a senior lead.
Yes, if you have transitioned from executing tasks to owning services rather than working exclusively under the direct supervision of a senior lead.
Yes, if you have moved past simple bug fixes to owning entire features or services. It is less suitable if you are still working exclusively under the direct supervision of a senior lead without independent decision-making power.
What if my background is at a small startup rather than a mid-sized company like Airbyte? Yes, emphasize how your technical decisions prevented debt and the breadth of your impact across the stack to demonstrate end-to-end ownership.
Yes, emphasize how your technical decisions prevented debt and the breadth of your impact across the stack to demonstrate end-to-end ownership.
Focus on the breadth of your impact and how your technical decisions prevented future technical debt. Hiring managers at startups and large firms alike value engineers who can wear multiple hats and solve problems with limited resources.
What if I don't have access to specific latency or cost-saving percentages? Use proxy metrics like user count, task frequency, or reduction in manual support tickets to prove the scale and reliability of your contributions.
Use proxy metrics like user count, task frequency, or reduction in manual support tickets to prove the scale and reliability of your contributions.
Normalize using proxy metrics like the number of users impacted, the frequency of a task you automated, or the reduction in manual support tickets. In this resume, Rohan uses '45,000 active users' to ground the technical work in real-world scale.
How much should I change before applying? Swap specific languages to match the job description while keeping the impact-heavy structure and mentorship bullets as key differentiators.
Swap specific languages to match the job description while keeping the impact-heavy structure and mentorship bullets as key differentiators.
Keep the structure of the impact-heavy bullets but swap the specific languages like Java or Node.js to match the job description. Do not remove the mentorship bullet even if the role doesn't explicitly require it, as it signals professional maturity.
What do hiring managers focus on at this level? They look for force multipliers who improve team efficiency through framework standardization and clean, maintainable code.
They look for force multipliers who improve team efficiency through framework standardization and clean, maintainable code.
They look for 'force multipliers' who write clean code while making the rest of the team more efficient. This is reinforced in the resume through the standardization of frameworks and the creation of self-service onboarding flows.
