Backed by world-class investors like Benchmark, Spark Capital, Craft Ventures, Greylock, Y Combinator, and more, we want you to help us continue to scale quickly and make an even greater impact.

We are seeking a *Senior Software Engineer - E4* to act as a senior technical leader with a full-stack focus. In this role, you will solve complex technical challenges, provide technical guidance, and shape the architectural vision that spans multiple teams and impacts the broader organisation.

Who You Are:

* 8+ years of experience building and shipping scalable web and mobile applications with a strong full-stack background.
* Proven expertise in system design, distributed systems, and modern software architecture with the ability to deliver in a fast-paced environment.
* While experience with our stack (Python/Django, Celery, MySQL, Redis, ElasticSearch, React, React Native) is preferred, it’s not mandatory.
* Strong communication & collaboration with product and design teams to create user-centric and technically sound products.
* Passionate about AI and its potential to transform software development and products with AI integration, automation, or tooling. Hands-on experience is a strong plus.
* Experience mentoring and providing technical guidance to others

What You'll Do:

* Design and architect scalable, high-impact solutions for large and complex projects.
* Collaborate closely with cross-functional teams to prioritise and execute on the highest ROI projects and deliver at aggressive timelines.
* Provide technical leadership and mentorship to senior and junior engineers.
* Drive strategic technical decisions and architecture reviews that influence cross-team initiatives and long-term product vision.
* Champion the adoption and integration of AI to enhance development workflows, automate routine tasks, and innovate product capabilities.
* Maintain high standards of code quality, reviews, technical feedback, and documentation.
* Maintain peak team productivity by juggling multiple priorities in a fast-paced environment.

Why Join Instawork?

Everyone at Instawork works across the stack. You’ll have the opportunity to work on backend systems at scale, build frontend user experiences, and collaborate with Product & Business to make the product meaningful.
We work hard and we work fast. We err on the side of being bold and embrace + celebrate failure, because we’d rather make bets on great features at the expense of shipping some bad ones.
You will be at the forefront of AI adoption in software development and product innovation. We encourage everyone to learn and harness AI’s potential to drive personal and professional growth.

Perks:

Free snacks
Health Insurance

Our Values

Empathy, Trust & Candor
We put ourselves in the shoes of our colleagues and customers and don’t shy away from uncomfortable conversations, instead building trust through honest and direct feedback.
Bias for Action
We practice high-velocity decision-making, clear-eyed that we often operate with incomplete information. Growing quickly means it’s OK to be wrong, so long as we learn from our mistakes and course correct!
Always Be Learning
We’re a curious bunch, and with AI transforming our workplace we encourage everyone to learn from each other, compounding our knowledge and experience to help us change an entire industry.
Act Like an Owner
We work long, hard, and smart, building products that delight our users and drive growth. Your ability to impact Instawork is limited only by your courage and conviction, not your job description.
