We’re looking for a Senior Software Engineer who brings strong full-stack experience, sharp design instincts, and a passion for building systems that are clean, testable, and production-ready. In this role, you’ll help shape our platform end-to-end—working across backend services, modern front-end interfaces, and the automation pipelines that power delivery. You’ll collaborate closely with product, design, and engineering teammates to turn ideas into dependable software, while helping raise the bar for quality, performance, and security across our stack. Responsibilities: - Build and evolve full-stack features using Python/Django on the backend and React on the frontend. - Write clean, efficient, well-tested code that reflects strong engineering standards. - Design and maintain CI/CD workflows to support fast, reliable releases. - Partner with cross-functional teams to refine requirements and translate them into scalable technical solutions. - Review code, champion best practices, and help define engineering standards. - Implement monitoring and performance tooling to ensure smooth user experiences. - Integrate APIs, databases, and third-party services into cohesive systems. - Investigate and resolve issues quickly to keep applications running at peak performance. - Stay current with new tools, frameworks, and architectural patterns. - Support and mentor other engineers while fostering a culture of curiosity and continuous improvement. Required: - 5+ years of professional software engineering experience, including full-stack development. - Strong backend development skills with Python and Django. - Solid experience building modern front-end applications, especially with React and ES6+. - Deep understanding of HTML, CSS, and JavaScript fundamentals. - Comfort with version control systems such as Git. - Experience with automated testing and TDD practices (e.g., Jest, Playwright, Testing Library, or similar). - Working knowledge of CI/CD concepts and implementation. - Experience deploying and managing applications in cloud environments such as AWS (EC2, RDS, S3). - Familiarity with containerization and orchestration tools like Docker and Kubernetes. - Experience with relational and NoSQL databases. - Strong grasp of web security fundamentals and common vulnerabilities (XSS, CSRF, etc.). - Familiarity with design and prototyping tools such as Figma, Sketch, or Zeplin. - Strong analytical thinking, problem-solving ability, and communication skills. - Healthcare domain experience is a bonus, not a requirement. ## About Cohort AI Inc. ## Company Overview - **One-liner**: Cohort AI is an AI-driven hiring engine that delivers pre-vetted, top-tier technical talent to fast-growing startups in days. - **Entity Type**: Private (assumed bootstrapped or early-stage; no funding rounds publicly disclosed) - **Headquarters**: Naperville, United States (with remote presence in India and Australia) - **Founded**: 2024 (domain created September 2024) - **Founders**: Not publicly named (company built by operators who previously scaled a hiring engine at Egen) ## Core Business - Primary industry: AI-powered recruiting / talent acquisition technology - Target customers: Startup founders, hiring managers, and VC-backed teams (B2B) - Mission: “Hire unicorn talent fast” – eliminate hiring drag and deliver elite candidates at lightning speed ## Products & Services - **SPEC (AI Recruiting Agents)**: A full-stack team of four AI agents: - **Sally the Sourcer**: Scans 5M+ profiles across LinkedIn, GitHub, and proprietary datasets to fill the pipeline. - **Pete the Prospector**: Turns cold leads into warm conversations via personalized, scalable outreach. - **Eva the Evaluator**: Runs technical assessments, resume reviews, and coding challenges to shortlist top-fit talent. - **Charlie the Closer**: Handles final interviews, offer logistics, and onboarding to reduce drop-off risk. - **Service Model**: Cohort acts as a talent delivery engine – not a marketplace. Customers pay for results (top 3 pre-vetted engineers delivered in 72 hours), not activity. ## Market Standing - **Valuation**: Not disclosed - **Key Metrics**: - Revenue: Not publicly available (likely pre-revenue or early traction) - Total Funding: Not publicly disclosed (company claims “no pitch decks”) - Team size: ~11 employees (LinkedIn) - Monthly web traffic: ~5,000 visits (thecohort.ai) - **Notable Investors/Partners**: None publicly mentioned - **Growth Signals**: - Launched publicly in late 2024 with a product built from first principles. - Recruiting for multiple senior remote roles across engineering, marketing, and data (indicates scaling). ## Competitive Advantages - **Speed**: Delivers top 3 candidates in under 72 hours vs. traditional 6-week processes. - **Full-stack AI agents**: Cover sourcing, prospecting, screening, and closing – fully automated. - **Outcome-based pricing**: Pay only for delivered, pre-vetted candidates; no subscription or per-activity fees. - **Built by operators**: Founders previously built and scaled hiring engines for high-growth tech companies (e.g., Egen), giving them firsthand insight into hiring pain points. - **Precision targeting**: AI scores candidates on skills, culture fit, and trajectory, learning from hiring team decisions. ## Strategic Focus - Continue expanding the SPEC agent platform and improving accuracy. - Scale the team to support increasing demand from startups. - Maintain a remote-first, global hiring approach (US, India, Australia, and remote-anywhere roles). ## Why Work Here - **Remote-first culture**: Most roles are fully remote (US or India), with flexible location options. - **AI-first engineering**: Opportunity to build production-grade AI systems and data pipelines from scratch. - **Tight-knit team**: Small (~11 people), flat structure, high ownership. - **Impact**: Shape a product that directly solves a critical pain point for startups. - **Values**: “No fluff. No pitch decks. Just results.” – fast-paced, execution-oriented environment. - **Tech stack**: Python, SQL, Google Cloud, AWS Lambda, Docker, PostgreSQL, Elasticsearch, GitHub Actions, microservices. ## Sources 1.
