Software Engineer Job Description

A Software Engineer designs, builds, and maintains the systems that power your product. The best hires bring strong fundamentals in algorithms and system design, a bias for clean and maintainable code, and the judgment to make pragmatic tradeoffs under real-world constraints. They collaborate across the stack, ship features end-to-end, and leave codebases better than they found them — reducing tech debt while consistently delivering user value.

Key skills

Object-oriented and functional programmingData structures and algorithmsSystem design and architectureREST and GraphQL API designUnit and integration testingVersion control with GitCode review and pair programmingPerformance profiling and optimization

Responsibilities

  • Design and implement features across multiple layers of the application stack
  • Write clean, well-tested, and documented code that meets agreed acceptance criteria
  • Participate in architecture discussions and contribute to technical decision-making
  • Conduct thorough code reviews that improve quality and share knowledge across the team
  • Identify, debug, and resolve production issues in a timely manner
  • Collaborate with product managers and designers to refine requirements before implementation
  • Continuously improve engineering processes, tooling, and developer experience
  • Monitor system health and proactively address performance and reliability risks

Requirements

  • 3+ years of professional software development experience in any modern language
  • Solid grasp of data structures, algorithms, and complexity analysis
  • Demonstrated ability to design and deliver end-to-end features independently
  • Experience writing automated tests and maintaining high coverage on critical paths
  • Strong communication skills and a collaborative, team-first mindset
  • Proven track record of shipping production software in a fast-moving environment

Nice to have

  • Contributions to open-source projects or a public portfolio of personal projects
  • Experience working in a distributed or remote-first engineering team
  • Familiarity with cloud-native deployment patterns (containers, serverless)
  • Exposure to domain-driven design or event-driven architecture
  • Experience owning a service through a full incident lifecycle, from on-call alert to blameless post-mortem and follow-up fixes
  • Comfort reading and safely refactoring an unfamiliar legacy codebase without a comprehensive test suite

What to look for in a great Software Engineer

Beyond technical correctness, look for engineers who demonstrate clear thinking about tradeoffs. During interviews, the best candidates articulate why they chose one approach over another — not just what they built. Look for curiosity: do they ask clarifying questions before diving in? Do they consider edge cases unprompted? Strong engineers also show ownership: they talk about outcomes, not just tasks. Watch for communication quality during the debrief — someone who can explain complex ideas simply will be a force multiplier on your team.

Interview questions to ask a Software Engineer

Ask candidates to walk through a technically complex project they owned: what was the hardest tradeoff they made, and what would they do differently? Follow up with a system design question scaled to their seniority level — not to test memorized patterns, but to observe how they think through constraints. Include a debugging exercise with a subtle bug in a short code snippet. Finally, ask about a time they disagreed with a technical decision and how they handled it — this surfaces communication style and professional maturity under real conditions.

Where to source Software Engineers

GitHub, LinkedIn, and specialist job boards like Stack Overflow Jobs and Hired are strong starting points. Employee referrals consistently yield high-quality candidates because engineers tend to recommend peers whose work they know firsthand. Open-source communities and local meetups surface motivated engineers who are actively building. For senior hires, consider reaching out directly to contributors of well-maintained projects in technologies your team uses. Technical screeners that let candidates demonstrate skill asynchronously reduce scheduling friction and widen the top of your funnel significantly.

Red flags when hiring a Software Engineer

Watch for candidates who describe systems only in buzzwords but cannot explain a single trade-off they made under real constraints. A strong engineer talks concretely about why they chose a queue over a cron job, or how they debugged a race condition. Be cautious of people who blame every past failure on teammates or legacy code without owning their part, and of those who have never written a test in anger. Resume inflation shows up when 'led' really meant 'watched'. Ask for a specific bug they fixed end to end; vague or rehearsed answers, or an inability to reason about failure modes and data consistency, usually signal shallow hands-on depth.

How an ATS speeds up hiring a Software Engineer

Engineering roles attract high volume, so an applicant tracking system earns its keep by keeping the loop structured. With Pitch N Hire you post the role to multiple job boards at once, then filter applicants by concrete signals such as language experience or open-source links before anyone opens a CV. Structured interview kits let each panellist score the same competencies (system design, code quality, collaboration) on a shared scorecard, so decisions rest on evidence rather than the loudest voice. Take-home or live-coding notes attach to the candidate record, feedback is collected in one place, and the hiring manager sees where every candidate sits, which shortens time-to-offer without cutting rigour.

FAQ

Hiring a Software Engineer — FAQs

What does a Software Engineer do? +
A Software Engineer designs, writes, tests, and maintains code that powers applications and systems. They work across features, fix bugs, review colleagues' code, participate in architectural planning, and collaborate closely with product and design to turn requirements into working software. The role spans the full development lifecycle from scoping to deployment.
What skills does a Software Engineer need? +
Core skills include proficiency in one or more programming languages, strong understanding of data structures and algorithms, experience with version control, and the ability to write automated tests. Equally important are system design intuition, effective communication, and the discipline to write maintainable code. Cloud familiarity and CI/CD knowledge are increasingly expected at most companies.
How much does a Software Engineer earn? +
Compensation varies considerably by location, company size, industry, and seniority. Mid-level engineers at well-funded tech companies in major markets typically earn meaningfully more than those at earlier-stage startups or in lower cost-of-living regions. Total comp often includes equity and bonuses. Always benchmark against current market data for your specific geography and stack rather than relying on a single figure.
How long does it take to hire a Software Engineer? +
For a mid-level generalist, a well-run process typically runs three to six weeks from posting to signed offer, assuming a clear scope and prompt panel feedback. Senior and specialist hires take longer because the pool is smaller and notice periods stretch. The biggest avoidable delays are slow scheduling between interview rounds and vague requirements that force rework. Keeping the loop tight, giving fast decisions, and lining up a competitive offer early are what compress the timeline most.
Should I hire a Software Engineer full-time or on contract? +
Hire full-time when the work is core to your product and you need someone who accumulates domain knowledge, owns long-lived systems, and mentors others. A contractor or staff-augmentation engineer fits short bursts of well-scoped work, a specialist skill you need briefly, or a delivery deadline you cannot staff in time. Contract talent ramps faster on defined tasks but usually leaves with the context. Many teams blend both: full-timers hold the architecture while contractors absorb overflow.
