Job description
We're looking for a Senior Software Engineer to join our engineering team building cross-channel management tools that turn massive, complex data streams into impactful actions across paid search, social, and retail media.
In this role, you'll play a key part in designing, developing, and maintaining high-performance Java applications. You'll architect scalable RESTful APIs, optimize complex database queries for high-throughput data, and help drive our technical evolution as we scale our systems.
What You'll Do
- Core Engineering: Write robust, efficient, and scalable backend code primarily in Java.
- API Architecture: Design, develop, document, and consume robust REST APIs for seamless integration with internal microservices, frontend apps, and external partners.
- Database Optimization: Write and optimize complex SQL queries using major relational database management systems (e.g., MySQL) to ensure high data integrity and performance at scale.
- Collaboration & Workflow: Manage version control using Git and GitHub, focusing on clean code history, clear branching/merging practices, and collaborative code reviews.
- System Evolution: Contribute to modernizing our architecture, helping transition and scale services for peak performance.
What We're Looking For
- Java Expertise: 5+ years of professional software development experience, with dedicated, hands-on expertise developing and maintaining enterprise Java applications.
- Databases: Strong proficiency in SQL and relational database design using a major RDBMS like MySQL.
- API Development: Proven, professional experience in building and consuming RESTful web services.

- Education: Bachelor’s degree in Computer Science, Software Engineering, or a related technical field.
Nice-to-Haves
- Hands-on experience deploying, managing, or monitoring applications on cloud platforms such as GCP.
- Hands-on experience with modern data stacks, particularly BigQuery and dbt.
- Experience transitioning legacy Java/Tomcat/MySQL tech stacks to modern cloud-native setups.
- Familiarity with modern AI productivity and coding tools (e.g., Claude, Gemini) to accelerate development workflows.

Prepare your application
Use the description above to assess your fit for BarkleyOKRP. This checklist is guidance from Resumize, rather than additional requirements from the employer. Imported listings can be shortened or change after collection, so confirm the complete description and current availability before sending an application.
Match requirements to evidence
Identify the responsibilities and skills the employer explicitly names. For each important requirement, choose one example from your work, education, training, or projects. Explain what you did, how you did it, and what changed as a result. Include a measurable outcome when you can support it. If you lack a requirement, describe related experience accurately instead of adding an unfamiliar skill to your resume.
Put the most relevant examples near the top of your resume. Keep job titles, dates, qualifications, and contact details consistent across your application materials. Use the employer’s terminology when it describes your experience accurately; a copied list of keywords does not explain your contribution. A short, specific bullet is easier to review than a paragraph that mixes several unrelated duties.
Check the working arrangement
Confirm the location, schedule, employment type, and any eligibility requirements on the employer’s site. A remote label does not establish worldwide eligibility or flexible hours. If compensation, benefits, equipment, travel, or contract duration are missing from this listing, write down your questions for the recruiter. Do not assume details from another opening at the same company apply to this role.
Review before submitting
Follow the employer’s requested file format and application instructions. Open your exported resume and check that its text is selectable, its sections read in order, and its links work. Proofread names, dates, and contact information. Share confidential work samples only when you have permission, and use an anonymized example when necessary.
Submit through a trusted employer or recruiting destination. If the original listing has disappeared, search the employer’s careers page for the title rather than assuming the vacancy remains open. Save the application date, job reference, and the version of your resume you sent. Those details help you prepare for a later conversation and avoid submitting conflicting information through several job boards.
Review your resume for writing and readability feedback, or browse other openings if this opportunity is unavailable.
