We are seeking a Senior Software Engineer to contribute to our next level of growth and expansion.

This is a hybrid role split evenly between hands‑on software development and internal developer enablement. The engineer will act as a force multiplier for engineering teams by reducing friction across the development lifecycle, providing clear and opinionated guidance, and improving internal tooling (including the company’s AI coding tools such as Claude). We are hiring two engineers and aim to onboard as soon as possible.

• Contribute to engineering initiatives as a full software developer, delivering production‑quality features and services.
• Write, review, test, and maintain clean, reliable, and scalable code following standard engineering workflows (PRs, code reviews, CI/testing).
• Provide internal developer support by answering specialized, contextual questions across the engineering ecosystem (tooling, libraries, standards, and patterns).
• Guide engineers on local development environment setup, Unix/Bash workflows, and day‑to‑day tooling usage.
• Advise teams on internal tools and frameworks, clearly explaining technical trade‑offs and recommending best paths forward.
• Identify repetitive friction points and automate workflows through scripts, templates, and improved tooling.
• Partner with the team to embed AI know‑how into the company’s AI coding tools (e.g., Claude) and enable smarter developer experiences.
• Contribute to infrastructure‑as‑code and internal platform efforts using Terraform, especially in AWS‑based environments.
• Help teams make identity/security framework decisions (e.g., Okta, Auth0) based on use case and organizational standards.
• Operate effectively in ambiguous environments, establishing clarity where documentation or standards don’t yet exist.

• 7–10 years of professional software engineering experience, with strong fundamentals and the confidence to provide clear, opinionated guidance.
• Strong proficiency in either Python or .NET (we are hiring two engineers—ideally one strong in each to complement the stack).
• Solid experience working in Unix/Linux environments and Bash/scripting.
• Hands‑on experience with Terraform and infrastructure‑adjacent work (AWS‑based environments preferred).
• Familiarity with identity/security frameworks such as Okta and/or Auth
  0.
• Demonstrated ability to act as an internal consultant: diagnose problems quickly, communicate trade‑offs, and recommend solutions.
• Strong communication skills (written and verbal), with a coaching/mentoring mindset.
• Proactive and independent: naturally seeks opportunities to improve, automate, and simplify.
• Comfortable switching between deep technical work and developer support without losing momentum.
• Nice to have: exposure to AWS architecture, but not required to be an AWS expert (dedicated architecture expertise exists within the team).

• You will need excellent written and verbal English for clear and effective communication with the team.

• In order to thrive in this role, you must have at least 6+ years of experience in data engineering or similar roles.

• Certifications in AWS (we are AWS Partners), Databricks, and Snowflake.
• Access to AI learning paths to stay up to date with the latest technologies.
• Study plans, courses, and additional certifications tailored to your role.
• Access to Udemy Business, offering thousands of courses to…
