## Description

As a Senior Software Engineer, Full-Stack, you will create new products and features end-to-end which directly contribute to G2's key organizational goals. Your responsibilities will center around building and delivering new products and features to production with confidence in their performance. As a technologist, you will be a key voice in defining and refining product concepts to take advantage of opportunities afforded by AI and agent technology & greater industry developments. You will adopt industry-leading engineering techniques and leverage "agent-first" ways of working to deliver products, reflecting the realities of today's software development lifecycle.

In This Role, You Will:

Build new products and features [60%]:

 * Contribute across the full software stack to deliver user journeys to production, owning implementation quality from architecture to release
 * Apply sound software engineering and system design principles to produce solutions that are observable, maintainable, scalable, and production ready
 * Design and build product features and agents that use frontier models with prompting, context, tools, and model reasoning to fulfill user journeys, generate content, and automate processes
 * Validate solutions against functional requirements using both traditional QA methods, evals, and tracing to ensure quality is measurable and reproducible
 * Incorporate agentic software engineering techniques into the development workflow across the SDLC, from planning, design, implementation, testing, and maintenance

Actively participate in product definition as a technologist [35%]:

 * Drive product definition with designers and PMs: ideate, explore, and prototype with stakeholders, then cut down possible options to arrive at deliverable, but well-rounded solutions
 * Wholly conceive and ship features & MVP iterations early in the product definition phase that directly advance high-visibility organizational goals
 * Strike the right balance between investment in UX quality and tending to practical business needs through the product development process.
 * Partner with other engineering stakeholders to identify what technology makes possible, and what makes implementing a given product or feature hard. Bring that perspective into project scoping and prioritization

Be a source of influence for other engineers on the team [5%]:

 * Share knowledge, techniques, and agentic software engineering practices in async formats and dedicated venues, like technical discussions and team meetings
 * Champion the use of AI solutions for engineering and product tasks, accelerate product velocity and team's execution
