Own monetisation and activation end-to-end: subscriptions, paywalls, billing, onboarding and first-use activation. Build analytics and experimentation foundations (events, funnels, A/B tests). Integrate with payment providers and handle failure modes (declines, webhooks, disputes). Drive data-informed experiments to improve funnel and revenue.

Own and build enterprise identity and tenancy: implement SAML/OIDC federation and SCIM provisioning, design self-serve tenancy (orgs, seats, roles, entitlements), create audit/admin surfaces (access logs, session policy, de-provisioning), and partner on rollouts to ensure frictionless enterprise deployments.

Lead technical direction for AI-native agent products, solve high-leverage engineering problems, improve reliability and evaluation, partner with product and customer teams, mentor engineers, and ship production-grade autonomous agent features rapidly.

Lead a 4–8 person AI-native engineering team to deliver production agent orchestration features. Coach engineers on product thinking, agentic workflows, and eval practices; remain hands-on in code, ensure quality and reliability, run postmortems, and hire top talent.

Build and ship AI-native, agentic products end-to-end: design LLM-powered workflows, prototype with frontier models, collaborate with product/design/customers, ensure reliability through continuous shipping and on-call ownership, mentor engineers, and iterate based on customer feedback to scale intelligent agents into production.

Lead and scale globally distributed engineering teams, define technical vision and roadmaps, architect and operate internet-scale distributed systems, drive agile continuous delivery practices, elevate engineering quality and culture, and communicate technical strategy across product and executive stakeholders.

Talent-network posting to collect engineers for future openings across full-stack, backend (Golang), frontend (React), mobile (iOS/Android/React Native), blockchain, AI, DevOps, security, data, and QA. Applicants should state domain, core technologies, location/time zone, and share links to profiles or projects. Fully remote; must have right to work in the country you are based.

Build and optimize customer-facing features with a frontend focus, owning end-to-end delivery. Work across the stack to implement APIs and data flows, improve performance and accessibility, debug production issues, and collaborate with product and design to ship high-quality, tested interfaces.

Design and execute manual and automated test strategies for Sentral and StudentPayPlus. Build and maintain Selenium-based frameworks, perform API and database testing (MSSQL, Cosmos DB), track defects, collaborate with product and development teams in Agile/CI/CD environments, and drive QA process improvements.

Technical lead responsible for designing and owning scalable, resilient cloud systems for conversational search and content intelligence. Build event-driven architectures, embed DevSecOps, optimize CI/CD and AWS costs, guide Generative AI/RAG integrations, write Node.js/TypeScript backend services, mentor engineers, and collaborate with product and design to balance delivery and architectural health.

Design, build, and operate resilient, secure, cost-efficient cloud backend services for conversational search and content intelligence. Own distributed systems, CI/CD, DevSecOps, FinOps, and integrate Generative AI/RAG workflows (e.g., AWS Bedrock) using Node.js/TypeScript on AWS.

Lead technical support engineering for enterprise customers: perform deep debugging across polyglot stacks, troubleshoot Sentry SDK implementations, build deterministic agentic support systems using MCP and Sentry APIs, and drive automation and product feedback loops. Act as technical lead for AI-enabled support tooling and liaise with product teams to prioritize platform fixes.

Design and develop complex software solutions for a banking platform, leading engineering efforts, and mentoring team members in a high-impact role.

Build and own foundational full‑stack systems for Propeller's 3D mapping platform: design, implement, test, ship, and maintain services and UI, collaborate across teams, and support adoption of shared patterns.
