Open Positions

  1. Data Analytics Developer

    Our lively DC-based digital advertising agency is looking for a data analytics developer to join our team. In this role, you’ll work cross-functionally with our strategists, ad buyers, and developers, and directly with our clients’ technical teams..

    About the role

    Every client’s tech stack is different, especially among C+K’s highly diverse client base, which ranges from nonprofits to party committees to classic ecommerce and retail. In this role, you will help assess, advise and enact improvements to our clients’ marketing tech stack (e.g. their analytics, CRM, ESP, multi-touch attribution system, etc.), as well as the C+K’s team ad buying platforms and workflows (e.g. our DSPs, Facebook, Google Ads, etc.), especially in the areas of ad performance reporting, dashboarding, and reporting automation. In this role, you’ll need to understand the business objectives of the strategy team, then use your technical skills to deliver solutions that either 1) save time in reporting workflows, 2) improve accuracy, 3) provide more data-rich/actionable reports for optimizing ad campaigns, or 4) prepare insightful client-facing dashboards/visualizations (or in some cases, if the stars align, all four in one project).

    What we’re looking for (the full list isn’t required, but the more the better!)

    Prerequisites: 3+ years of experience in a role similar to the one described above, or focused on some or all of the following:

    • Marketing Work-Product Focus: A clear understanding of direct-response ad campaigns and marketing, how they’re measured, what systems are used, the data these campaigns produce, and how that data is used is a must. Ideally this experience is focused on empowering ad buyers and analysts focused on acquisition and optimization of results (e.g. email list growth, ecommerce, fundraising, app install campaigns, etc.).
    • Tools used: In this role, data comes from the tech needed to run successful paid media campaigns, including .com/app analytics, CRMs and ad platform data such as the paid search, paid social, and programmatic display and video buying platforms. From there, experience with setting up data-flow integrations, automation, dashboarding and reporting using solutions such as Tableau, Google Data Studio, Google Cloud / Google Big Query, and other connectors and API solutions (Supermetrics, Stitch, DBT, Fracture, etc.) is a must, and the primary focus of this role.
    • Work Style & Tech Stack Experience: In this role it’s critical to have a high level of proactiveness and self-starting in unpacking (usually less-than-ideal) client analytics/CRM/martech stacks (especially SalesForce, EveryAction/ActionKit), and find a way to use your skills to add value. Often this will mean working on parallel tracks to learn the tech stack and first apply some short-term band-aids, while also researching and recommending what long-term tech changes should be made to achieve a more advanced/powerful tech/ad data stack.
    • Technical Skills: Data analysis skills in Excel or Google Sheets are an important foundation (since many of our team’s analyses start here, and most clients think in these terms). Experience setting up and improving the above mentioned ad channel/marketing/reporting tech is a must. Comfort working with Git and the command line, and programming languages such as SQL, R, and Python are also key. Experience with statistical methods (significance testing, regression analysis, etc), data warehousing (Redshift, AWS Athena, Databricks and Snowflake), or data pipeline frameworks (Airflow and abt) are nice to have, and if you’re keen but haven’t had the opportunity to learn, we can give opportunities and space to learn more!


    Compensation commensurate with experience and skills. Our compensation assumption (base + annual bonus) is $95k-$135k.


    C+K offers a full benefits package which includes: medical insurance (Gold-level reference plan, 100% paid by C+K for C+K employees, and 50% paid for dependents), options for dental and vision insurance, SIMPLE IRA with company matching, short-term disability, flexible spending accounts, transportation benefits, paid time off and paid holidays. C+K is an equal opportunity employer.
