Lumilens Off Campus Drive 2026 | Software Test Automation Engineer | Bengaluru — Apply Now

Lumilens Off Campus Drive 2026 – full job details

Lumilens builds photonic interconnects — the optical links that carry data between chips inside AI data centres. The company recently came out of stealth with more than $900 million in funding and a $5.5 billion valuation, which is unusual for a hardware startup and tells you how much demand there is for faster connections between AI accelerators.

The Lumilens Off Campus Drive 2026 hires into the Early Talent programme for a Software Test Automation Engineer, also described as an Optical Product Test Engineer specialising in software automation. You will validate complex systems at Layer 1 and Layer 2 using traffic generators such as IXIA, and build Python-based test frameworks that run against real optical hardware.

This sits at an interesting intersection: part software engineering, part networking, part optics and lab instrumentation. If you liked your networking and electronics coursework but want to write code rather than design circuits, the role fits neatly. Lumilens describes the programme as being for people who do not want to wait years before working on meaningful engineering problems.

Key responsibilities

• Develop, maintain and execute automated test cases in Python.
• Perform functional, regression and performance testing on Layer 1 and Layer 2 network systems.
• Validate hardware and software integration with optical interfaces and network switches.
• Configure traffic generators such as IXIA to simulate network environments and evaluate performance.
• Work with developers and hardware engineers to identify, reproduce and resolve defects.
• Document test cases, results and defects in test management tools.
• Maintain code and test assets in GitHub or Bitbucket, and keep improving the test frameworks.
• Partner with design and manufacturing teams to build test software for high-volume optical component manufacturing.
• Own manufacturing test scripts — creation, maintenance and change control.
• Work with software, IT and database teams on reliable, cost-effective and scalable manufacturing test data solutions.

Lumilens Off Campus Drive 2026 eligibility criteria

• 2026 or 2025 graduating candidates from BE, BTech, ME, MTech or MS Research programmes.
• Electronics, ECE, Computer Engineering, Computer Science, Telecommunications or a related discipline.
• Strong proficiency in Python for test automation.
• Good understanding of Layer 1 and Layer 2 networking protocols.
• Exposure to optical testing, network switches and traffic generators such as IXIA.
• Ability to debug problems in complex networking environments.
• Experience with Jenkins, ArgoCD or other CI/CD tools, plus shell scripting for automation and environment setup.
• Good written and spoken English, including presentation skills.

Additional technical exposure that strengthens a Lumilens Off Campus Drive 2026 application: C# .NET with OOP concepts and WinForms or WPF; hardware communication protocols including NI-VISA, SCPI, RS-232 and TCP/IP; lab instruments such as optical oscilloscopes, optical power meters and optical switches; SQL or NoSQL for test data logging; and version control with GitHub, Bitbucket or SVN. Experience with optical transceivers, particularly silicon photonics, is called out as a plus.

Selection process & tips

Applications go through a form rather than a job portal, so the resume you attach is doing all the screening. Lumilens has not published its interview stages; for an early-talent hardware-adjacent role, expect a screening call, a Python and networking technical round, and a discussion with the test engineering team.

Two things separate strong applicants here. First, know your OSI layers properly — be able to explain what actually happens at Layer 1 versus Layer 2, what a MAC address does, and how you would debug a link that trains but drops packets. Second, show automation you have actually written: a pytest suite, a script that drives an instrument over serial, anything that proves you can turn a manual test into a repeatable one. Coursework alone reads thin against this job description.

You will not be expected to know silicon photonics on day one. Reading a short primer on optical transceivers and why chip-to-chip optical links matter for AI clusters will, however, let you hold a real conversation in the interview.

How to apply for the Lumilens Off Campus Drive 2026

Applications for the Lumilens Off Campus Drive 2026 are collected through an online application form. Share an updated resume and complete every field on the form. Name your Python automation projects explicitly and list any networking or lab instrumentation exposure near the top — a recruiter screening for this role scans for Python, Layer 2 and IXIA first.
