Slow CI pipelines, flaky tests, observability that leaves you guessing, deploy processes that make people hold their breath — these are the things that nag at you, and you channel that into building practical solutions that measurably improve developer velocity and satisfaction.&nbsp;</p> <p>DevEx’s mandate is to maximize developer productivity and efficacy by providing best-in-class SDLC and Observability services, and by building systems that strategically apply GenAI to every stage of software development and operations. &nbsp;As a Lead Engineer on the DevEx team, you will own one or more subsystems or services across areas, delivering high-quality products both individually and collaboratively. &nbsp;</p> <p>In this role you will lead by example through your strong engineering skills, supported by the quality of the software you build, the insightful code reviews you provide to others, and the technical solutions you originate and implement. You must demonstrate high agency: combining systems thinking, a bias to action, and the willingness to challenge assumptions to assess and address the needs, challenges, and concerns of engineering teams at Arcesium.&nbsp;</p> <p><strong>Responsibilities<br></strong></p> <ul> <li>Design and build bleeding-edge systems for incorporating GenAI into software development and operations. &nbsp;This includes evaluating, building, integrating, and operating coding agents; building the infrastructure to make these agents effective and safe in our environment; and pioneering new ways to apply AI to the entire development lifecycle — all the way from idea prototyping to code generation and review, to testing, to deployment, to operational diagnostics&nbsp;</li> <li>Engineer and maintain the SDLC toolchain, including our source control platform and related CI/CD infrastructure, processes, and integrations, ensuring reliability and developer productivity&nbsp;</li> <li>Build and improve capabilities for feature flagging, progressive delivery, automated rollouts and rollback, and self-contained, on-demand test environments so that engineers can develop, test, and ship changes safely and with confidence&nbsp;</li> <li>Advance the Observability stack — encompassing metrics, logs, traces, and events — to help engineers solve operational problems efficiently&nbsp;</li> <li>Drive process improvements and evangelize engineering best practices; define and track metrics for developer productivity and satisfaction to ensure we are prioritizing work that has the most impact&nbsp;</li> <li>Act as a member of the broader Infrastructure organization at Arcesium, which provides the foundation upon which our customer-facing Platform runs&nbsp;</li> </ul> <p><strong>Qualifications<br></strong></p> <ul> <li>5+ years of relevant experience in software engineering, developer tooling, SDLC, or observability. &nbsp;However, we are interested more in what you’ve done, can do, and can grow to do, rather than the number of years you’ve been working.&nbsp;</li> <li>A proven track record of ownership of critical developer-facing systems and delivery of features that measurably improve developer productivity. &nbsp;You have owned and operated systems such as CI/CD infrastructure, source control platforms, observability tooling, or developer automation.&nbsp;</li> <li>Polyglot programming capability, with advanced ability in at least one language. We expect engineers within Infrastructure to be proficient and prolific software engineers. Languages in our ecosystem include Python, Java, Go, and Bash.&nbsp;</li> <li>Experience with AI/LLM-based developer tools (coding agents, AI-assisted code review, retrieval-augmented generation), AI-ecosystem infrastructure, and self-hosted models is highly valued.&nbsp;</li> <li>Ability to balance delivery with correctness, delivering timely solutions that are properly risk-managed for the needs of the business&nbsp;</li> <li>An inquisitive mind, strong collaboration and communication skills, with deep care for making your fellow engineers more productive&nbsp;</li> </ul> <p>Not all strong candidates will meet every single qualification as listed. &nbsp;We encourage you to apply if you are interested in this work, even if your experience doesn’t precisely match the job description. &nbsp;Your skills and passion will stand out, especially if your background is unconventional.&nbsp;</p> <p>The expected annual base salary for this position is $215,000 - $265,000. Our compensation package includes variable compensation in t
