SDE2 - Android Kotlin

Scoping

o Influence product discussions plan work sequencing handle edge cases

define correctness of the project and influence success KPIs.

o Do assessment of Technical feasibility for functional requirement and validate

the feasibility and coverage of Nonfunctional requirements.

o Engineering Milestone proposal and once the roadmap is finalised discover

the spectrum of changes.

Design

o Propose data and domain architecture propose alternative solutions with the

best one following Clean architecture and with the reason and understands the

clearing of tech debt in a given iteration.

o Propose LLD with reviews from SDE3/SDE4 design Test cases and increase

test coverage

o Propose ERDs with success criteria guard rail metrics and from security

aspects

Development Communicate effectively with crossfunctional devs provide and

validate effort estimates develop highquality code of approved design perform code

reviews dev testing should be exhaustive and coverage of all happy and sad flows on

testing sandbox and work closely with the QA team to ensure timely fixes of bugs.

Maintenance

o Ensure smooth functioning of engineering metrics like Crashes Nonfatal

crashes ANRs Memory Leaks App Startup time Battery optimisation etc

and diagnose concerns manage tech debt and contribute to knowledge

management through documentation.

o Escalate and involve relevant folks in Incident management and handle all

types of QA support tickets.

Innovation and Exploration

o Researching new technologies or trends analyzing customer or market needs

or identifying potential areas for process improvement or optimization.

o Designing and executing experiments prototyping new features or

functionality

Project Management

o Participate in project planning meetings help to define project scope and

timelines and contribute to risk assessments or mitigation strategies.

o Communicate with stakeholders or other departments to ensure that the work

aligns with the overall project goals and vision.

Documentation

o Detailed technical documentation that explains the design and implementation

of the software being developed. This could include documenting RIBs flow

data models entities state VM Presenters Listeners system architecture use

cases or other technical details

o Create or review design documents that outline the features or functionality of

the software being developed

Team Grooming Provide technical guidance to the team members through

engineering best practices and ensure they are followed conduct knowledge

transitions create a knowledge repository and train & support the business product

analytics QA on the engineering aspects.

Onboarding & Offboarding

o Organising orientation training and providing new employees with the tools

and resources they need to be successful in their roles. Help build

understanding of products and systems for new employees by conducting

rampup sessions.

o Conduct knowledge transfer sessions for exiting employees to ensure smooth

transfer of ownership with minimal disruption.
