Job Description

Reddit is a community of communities. It’s built on shared interests, passion, and trust and is home to the most open and authentic conversations on the internet. Every day, Reddit users submit, vote, and comment on the topics they care most about. With 100,000+ active communities and approximately 101M+ daily active unique visitors, Reddit is one of the internet’s largest sources of information. For more information, visit redditinc.com.

The Core Experience organization's mission is to empower people to participate in global conversations through communities. Poster Experience specifically focuses on the user journey in creating posts at Reddit, which is the main source of user content for the product. We aim to make it easier, faster, and smarter to create and participate in conversations, and we drive several core product metrics for the entire Reddit ecosystem. We are also actively using ML and LLMs to improve these journeys.

This is a high impact role where you will own projects from ideation to production, working with our super-talented cross-functional team. You'll closely collaborate with product and design teams, and be responsible for the engineering architecture and execution of key product features. You will also identify opportunities to use, configure, and deploy ML models and/or LLMs to create or improve product features. You will be providing technical direction to junior engineers.

Fully remote within US or Canada

What You’ll Do:

  • Design, build, and ship backend services, experiments and products for millions of users.
  • Understand and apply machine learning models and techniques to improve the user experience of our products, including usage of LLMs (large-language models).
  • Provide technical direction to junior engineers, holding a high bar for software quality.
  • Communicate effectively, within the team and across disciplines. Work closely with product managers and designers to craft compelling user experiences.
  • Contribute meaningfully to our team’s strategy. We give everyone a seat at the table and encourage active participation in planning our future. Don’t just come along for the ride.
  • Participate in product reviews and team meetings, providing technical insight. Help scope, estimate, and prioritize between conflicting needs.
  • Foster a healthy engineering culture and collaborate with other engineers.

Who You Might Be:

  • 5+ years of software development experience in one or more general-purpose backend programming languages; Go, Python, Rust, Ruby.
  • Experienced with GraphQL, REST, HTTP, Thrift or gRPC basics, and the ability to design and implement maintainable APIs.
  • Experience with integrating ML models and/or LLMs into user-facing products.
  • Experience providing direction and/or mentorship to junior engineers.
  • Strong organizational skills, the ability to prioritize tasks and keep projects on schedule.
  • BS degree in Computer Science, a similar technical field of study or equivalent practical experience.
  • Entrepreneurial spirit. You are self-directed, innovative, and biased towards action in fast-paced environments. You love to build new things and thrive in ambiguity and even failure.
  • Excellent communication skills. You collaborate effectively with teams in a fully remote environment and discuss complex topics with technical and non-technical audiences.

Benefits:

  • Comprehensive Health benefits
  • 401k Matching
  • Workspace benefits for your home office
  • Personal & Professional development funds

Safe Remote Job Search Tips

Verify Employer Thoroughly

Research the company's identity thoroughly before applying. Check for a professional website with contacts, active social media, and LinkedIn profiles. Verify details across platforms and look for reviews on Glassdoor or Trustpilot to confirm legitimacy.

Never Pay to Get a Job

Legitimate employers never require payment for applications, training, background checks, or equipment. Always reject upfront payment requests or demands for bank details, even if they claim it's for purchasing necessary work gear on your behalf.

Safeguard Your Personal Information

Protect sensitive data like SSN, bank details, or ID copies. Share this only after accepting a formal, written job offer. Ensure it's submitted via a secure company system or portal, never through insecure channels like standard email attachments.

Scrutinize Communication & Interviews

Watch for communication red flags: poor grammar, generic emails (@gmail), vague details, or undue pressure. Be highly suspicious of interviews held only via text or chat apps; legitimate companies typically use video or phone calls.

Beware of Unrealistic Offers

If an offer's salary or benefits seem unrealistically high for the work involved, be cautious. Research standard pay for similar roles. Offers that appear 'too good to be true' are often scams designed to lure you into providing information or payment.

Insist on a Formal Contract

Always secure and review a formal, written job offer or employment contract before starting work or sharing final personal details. Ensure it clearly defines your role, compensation, key terms, and conditions to avoid misunderstandings or scams.
