• Design, develop, and maintain backend services written primarily in Golang • Build and evolve integrations with external CRM systems • Contribute to API design and service contracts • Participate in architectural discussions and help shape technical decisions • Ensure high code quality through testing, monitoring, and documentation • Collaborate closely with frontend engineers, QA, product, and other backend teams • Take ownership of features from design to production • Act as a technical reference within the team, with potential to grow into a lead role

• You're pragmatic, learn quickly, and have a proven track record of shipping products that matter. • You communicate clearly across disciplines and genuinely enjoy the dynamics of a cross-functional team where everyone contributes to solving the same customer problems. • As a product-minded backend engineer, you don't just implement tickets. You understand the "why" behind what you're building, challenge assumptions when needed, and proactively identify opportunities to create better outcomes. • You're comfortable discussing trade-offs with product managers, explaining technical constraints to business stakeholders, and collaborating with frontend and mobile engineers to design elegant end-to-end solutions. • You take ownership not just of your code, but of the outcomes. You move without being prompted, whether that's jumping into a customer issue, improving team processes, or mentoring colleagues. • Quality is non-negotiable for you. Automated testing, thorough code reviews, and security best practices are fundamental to how you work.

• Ownership in the design, development and delivery of trading system components • New feature implementation, bug fixing, and performance tuning • Partner with Financial Products and quantitative researchers on product delivery • Mentor team members and drive firm initiatives

• Design, build, and maintain robust backend services and RESTful APIs that power Toku’s omnichannel communication platform. • Build and maintain event-driven backend systems to support asynchronous workflows across messaging, notifications, and voice services. • Independently design microservices, define service boundaries, and reason about scalability, latency, data consistency, and architectural trade-offs. • Rewrite and migrate existing backend services (currently implemented in TypeScript) into Go and newer backend architectures. • Develop cloud-native backend systems on AWS, working closely with the infrastructure team to clearly articulate service requirements and operational needs. • Design and work with SQL-based data models, ensuring performance, correctness, and alignment with real product usage; contribute to NoSQL usage where appropriate. • Support communication and notification services across WhatsApp, SMS, email, and voice channels, handling communication metadata at scale. • Own backend services in production, including reliability, performance, observability, and continuous improvement. • Write clean, maintainable, and well-documented backend code, and participate actively in code reviews and technical design discussions. • Take initiative and drive backend problems through to solutions independently, collaborating effectively with peers across engineering.
