Why we read it this way (7)
The role is titled 'Senior Systems Engineer (Engineer 2)' — the parenthetical level designation suggests this is the second rung on an internal engineering ladder, which aligns with a Senior individual contributor.
This role sits at the boundary between SRE/operations (15-1244) and software development (15-1252). The JD emphasizes production infrastructure support, sysadmin, monitoring, capacity planning, and SLA management, which tips it toward 15-1244, but it also requires software development environment experience and scripting/automation, making 15-1252 a credible alternative.
Java and C/C++ are listed together as examples of supported languages under the 3+ year requirement; Java is used as the primary skill name with C/C++ as an alternative since the JD frames them as a group. PL/SQL is listed separately and retained as its own skill.
The 3+ years requirement is the highest role-level experience gate stated and is used as the overall years minimum; the 2+ and 1+ year figures are per-technology and captured on the relevant skills.
Bachelor's degree is listed under 'Preferred,' not required, so the degree requirement is set to None.
No compensation figures are provided in the posting.
The role is hybrid (St. Louis, MO area required); fully remote is not an option.
