Position Summary Arcesium seeks an accomplished Senior Software Engineer to join our Infrastructure Engineering organization, the team that builds and operates the core foundation Arcesium's applications run on. You’ll bring a deep commitment to reliability, scalability, and performance — and Infrastructure is where that commitment carries the furthest: a change made once, at the foundation, takes effect across the entire engineering organization. In this role you'll work across multiple functional areas within Infrastructure — including Developer Experience (AI, Observability, SDLC), Cloud Account Management, Compute, Connectivity, Customer Integration, Security, and Solutions Architecture — all built on top of AWS and Linux. You'll own one or more subsystems or services, delivering high-quality work both individually and as part of a collaborative team. You must demonstrate high agency : combining systems thinking, a bias to action, and the willingness to challenge assumptions to assess and address the infrastructure needs, challenges, and concerns of engineering teams across Arcesium. Responsibilities Build and operate reliable, well-instrumented infrastructure services — spanning all of Infrastructure’s functional areas — that other engineers and our customer-facing applications depend on for high availability Strengthen our compute platform, leveraging AWS and Kubernetes Craft tools and automated solutions that streamline processes, reduce toil, and improve efficiency — applying modern tooling and, where it fits, GenAI to accelerate how infrastructure is built and operated Take ownership of critical technology infrastructure built on top of multiple underlying technologies, tools, and programming languages Drive process improvements and evangelize engineering best practices; help define and track the metrics that ensure we are prioritizing work that has the most impact Act as a member of the broader Infrastructure organization at Arcesium, which provides the foundation upon which our customer-facing Platform runs Qualifications 3–5+ years of relevant infrastructure experience. 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. A proven track record of ownership of critical infrastructure systems and delivery of features that measurably improve reliability and efficiency. You have owned and operated systems such as Kubernetes, cloud infrastructure, DNS, or authentication services. 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. Experience running critical workloads in AWS is highly valued. An ability to balance delivery with correctness, delivering timely solutions that are properly risk-managed for the needs of the business. A curious mind, enthusiasm for technology infrastructure, strong collaboration and communication skills, and the drive to take initiative with the right combination of independence and teamwork Not all strong candidates will meet every single qualification as listed. We encourage you to apply if you are interested in this work, even if your experience doesn't precisely match the job description. Your skills and passion will stand out, especially if your background is unconventional. The expected annual base salary for this position is $175,000 - $210,000. Our compensation package includes variable compensation in the form of a year-end bonus, guaranteed in the first year of hire, benefits including medical and prescription drug coverage, and 401k contribution matching. The applicable annual base salary paid to a successful applicant will be determined based on multiple factors including without limitation the nature and extent of prior experience and educational background.    #LI-JS1 #LI-hybrid Arcesium's Personal Data Privacy Notice for Candidates is linked here .    Recruiting Security Emails from genuine Arcesium recruiters who are employees of the company will always come from the @arcesium.com domain.
