First seen by Alion on Oct 15, 2026.
SDE-3 (Full Stack):
Full-Time | Bengaluru, Work from Office
Qualifying Degree: B.Tech from a Tier 1 Institute | Experience: 7+ years
About the Role:
We're looking for a senior full stack engineer who can independently own end-to-end delivery across scalable backend systems (Go, Python, Node.js) and responsive frontends (Flutter, React.js). You've led feature teams, driven architectural decisions, and shipped mobile and web applications to production before - in a fast-paced, hardware-integrated product environment such as pet wellness or connected devices.
What You'll Do:
- Architect and develop secure, scalable backend services in Go, Python, and Node.js, with a strong eye on system design, performance, and reliability.
- Lead the design and development of intuitive mobile and web interfaces in Flutter and React.js, with a consistent experience across platforms.
- Own architecture decisions for one or more product modules end to end, balancing scalability, maintainability, and time-to-market.
- Design, implement, and continuously improve CI/CD pipelines that streamline development and deployment.
- Own app deployment to the Play Store and App Store, keeping releases compliant and shipping frequently.
- Design and integrate database and data-flow architecture that supports real-time, sensor-driven applications.
- Set and enforce testing standards, including automated testing within the CI/CD pipeline, to keep quality high across releases.
- Mentor SDE-1 and SDE-2 engineers, review code, and raise the engineering bar across the team.
- Work in an agile environment with cross-functional teams - sprint planning, estimation, and delivery included.
You Might Be a Fit If:
- You have a B.Tech in Computer Science or related field from a Tier 1 institute (IIT, NIT, BITS Pilani, or equivalent) - mandatory.
- You have 7+ years of full stack experience managing production systems at scale.
- You have strong proficiency in backend languages (Go, Python, Node.js) and frontend frameworks (Flutter, React.js).
- You have proven experience deploying and maintaining applications directly on the Google Play Store and Apple App Store.
- You have hands-on expertise designing CI/CD pipelines and a solid grounding in database design and management.
- You're familiar with Agile methodologies, with a track record of leading or mentoring engineers.
- Bonus: experience with IoT technologies and connected device ecosystems.
- Bonus: familiarity with cloud platforms and API integration.
- Bonus: prior experience in a startup or fast-scaling product environment.
- Bonus: strong problem-solving skills and attention to detail.
Why Join Us:
- Own architecture end to end on a category-defining, hardware-integrated product - not a legacy stack.
- Work across the full stack on real, sensor-driven data - not just CRUD.
- Take full ownership from day one, with a direct line to product and founding leadership.
- Build the team you wished you'd had - mentor, set the bar, and grow into the role.
