• Third-party integrations
• Cloud infrastructure
• CI/CD
• Security
• Observability

• Solid experience with SQL and/or NoSQL databases, database migrations, data modelling, and performance optimisation.
• Strong understanding of REST APIs, OAuth 2.0, webhooks, third-party SDKs, asynchronous processing, queues, workers, schedulers, retries, and idempotency.
• Hands-on experience with cloud infrastructure, production deployments, CI/CD, monitoring, logging, alerting, and incident response.
• Strong understanding of secure multi-tenant SaaS architecture, authentication, authorization, RBAC, tenant isolation, and credential management.
• Production experience integrating OpenAI, Anthropic, Google Gemini, or equivalent LLM platforms is required.
• Proven experience integrating social, business, marketing, or third-party platform APIs.
• Strong understanding of MarTech, product analytics, funnel measurement, attribution, and conversion tracking.
• Experience with several of the following: GA4, Google Tag Manager, UTM tracking, advertising attribution, product-event taxonomy, SaaS onboarding, activation, trial-to-paid conversion, lifecycle email, A/B testing, CRO, PQL identification, technical SEO, CRM/marketing automation, and retention analytics.
• Experience with Google Business Profile APIs is strongly preferred.
• Experience with Facebook, Instagram, TikTok APIs and subscription billing platforms such as Stripe is an advantage.
• Strong understanding of production AI recommendation or content-generation systems is an advantage.
• Comfortable taking ownership of an existing codebase and infrastructure built by another engineer, team, or agency.
• Strong problem-solving, debugging, documentation, and technical decision-making skills.
• Excellent written and spoken English with the ability to communicate clearly with technical and non-technical stakeholders.
• Highly autonomous, proactive, and comfortable operating with significant ownership and limited engineering resources.
• A senior hands-on builder who remains deeply involved in coding and technical execution rather than functioning purely as a people manager.
• Willingness to take complete responsibility for the reliability, security, scalability, and continuous improvement of a production application.

Requirements

• Experience: 3+ years
• Location: Remote (India)
