Software Engineer

Porter is building the operating system for intra-city logistics in India. With ~20 million orders per month, 500K+ daily-active drivers, and rapid scale ahead (1.5x growth expected next year), we solve complex real-world problems at massive scale, balancing speed, reliability, and cost efficiency in a highly operational environment.
Role Overview
As an SDE 3 at Porter, you will own and build large, business-critical systems operating at scale. This role goes beyond codingyou'll design scalable architectures, make thoughtful trade-offs, influence engineering standards, and mentor other engineers while working closely with product and business stakeholders.
You are expected to think from first principles, leverage AI responsibly, and build systems that are reliable, observable, and cost-aware.
Key Responsibilities
Technical & System Design
Design, build, and own scalable, high-availability distributed systems handling millions of transactions.
Drive Low-Level and High-Level Design, including APIs, data models, and service architectures.
Perform capacity planning, back-of-the-envelope calculations, and identify system bottlenecks early.
Ensure engineering excellence across reliability, observability, security, and cost optimization.
Coding & Execution
Write clean, maintainable, and testable production-grade code.
Apply SOLID principles, design patterns, and sound engineering practices.
Use AI tools to accelerate development while critically evaluating outputsknowing when to use AI and when not to.
Ownership & Delivery
Own end-to-end delivery of systemsfrom design to production and long-term maintenance.
Drive projects with high autonomy, handle ambiguity, and deliver under tight timelines.
Participate actively in operational reviews, incident management, and system improvements.
Collaboration & Leadership
Collaborate closely with Product, Data, and Business teams to balance tech decisions with real-world logistics constraints.
Mentor junior engineers, influence code quality, and help raise the engineering bar.
Contribute to hiring, technical interviews, and culture-building initiatives.
What We're Looking For
Experience
4+ years of software development experience (SDE 3 or equivalent role).
Proven experience owning and scaling production systems.
Experience working in fast-paced, high-ownership environments (startups or scale-ups preferred).
Technical Skills
Strong fundamentals in data structures, algorithms, and object-oriented design.
Hands-on experience with system design at scale.
Familiarity with modern backend stacks, distributed systems, and cloud infrastructure.
Strong understanding of engineering operations: monitoring, alerting, reliability, and performance tuning.
AI & First-Principles Thinking
Ability to use AI as a productivity tool, not a crutch.
Strong judgment to validate AI-generated outputs and reason independently.
Comfortable breaking down complex problems to fundamentals rather than pattern-matching solutions.
Leadership & Mindset
Strong sense of ownership and accountability (Own It).
User-first thinking with an understanding of business impact (User Obsession).
Bias for action and execution in ambiguous situations (Keep Moving).
Collaborative, empathetic, and resilient under pressure.
Desire to raise the bar for talent, quality, and execution.
Why Join Porter?
Build systems that operate at massive real-world scale.
Solve unique logistics and operational challenges.
Work in a culture that values ownership, frugality, speed, and impact.
Significant scope to grow beyond SDE 3 into technical or leadership paths.
