Role:

We're looking for a Senior Software Developer who can own the technical health and growth of our backend platform. You'll be part architect, part tech lead, part engineering manager. You won't just review code - you'll set the standard for how code is written, how systems are designed, and how the team thinks about quality, cost, and customer impact.

What You'll Own:

1. System Reliability & Upkeep:

- Own the health of a production multi-tenant Node.js/TypeScript backend serving real-time messaging traffic.

- Lead incident response, root cause analysis, and post-mortem culture.

- Identify and drive reduction of technical debt - proactively, not reactively.

- Ensure monitoring, alerting, and observability are in good shape (we use New Relic, Sentry, Pino structured logging).

- Work across multiple backend services and ensure they integrate reliably.

2. Scalable, Quality Engineering:

- Design and review system architecture decisions - schema changes, service boundaries, async workflows (we use Temporal.io), queue design.

- Drive engineering standards: code review culture, PR quality, test coverage, error handling patterns.

- Establish and enforce engineering practices that let the team ship fast without accumulating hidden risk.

- Evaluate build vs. buy decisions with a clear eye on long-term maintainability.

3. Cost Consciousness:

- Maintain a clear understanding of infrastructure costs (AWS, third-party APIs, LLM usage, DB compute).

- Actively flag cost anomalies and propose architectural or operational changes to address them.

- Balance engineering investment against business return - know when "good enough" is the right call.

4. Team Standards & Culture:

- Set a high bar for code quality - not pedantry, but clarity, maintainability, and correctness.

- Build a review culture where feedback is constructive, specific, and educational.

- Help engineers grow by pair debugging, design reviews, and code walkthroughs.

- Define and document coding conventions, architecture patterns, and engineering principles that persist beyond any individual.

5. Customer Empathy:

- Understand that the systems you build serve real D2C businesses who depend on them to communicate with their customers.

- Treat reliability issues with the urgency of a customer escalation, not a backlog item.

- Stay connected to what support and product teams are seeing from customers - let that shape engineering priorities.

6. Communication & Stakeholder Management:

- Translate technical complexity into clear, honest language for non-technical co-founders and stakeholders.

- Communicate risk, timelines, and tradeoffs clearly - no sugar-coating, no unnecessary alarm.

- Manage up: surface the right problems at the right time without waiting to be asked.

- Manage expectations - both internally with the team and externally with leadership.

7. Balancing Trade offs:

- Navigate the tension between shipping fast and building right - and be able to articulate why you chose one over the other.

- Know when to take on short-term debt and when to push back.

- Make architectural decisions that serve the next 18 months, not just the next sprint.

What We're Looking For:

- 4 - 6 years of backend software engineering experience.

- Strong command of TypeScript/Node.js in production.

- Deep understanding of multi-tenant SaaS architecture patterns.

- Hands-on experience with relational databases (MySQL/PostgreSQL), ORM usage (TypeORM or similar), and writing efficient queries at scale.

- Experience designing and operating async/event-driven systems (message queues, workflow engines, or similar).

- Comfort with cloud infrastructure (AWS preferred) and cost/performance monitoring.

- Strong pull request review discipline.

Strong Plus:

- Experience with real-time systems (WebSockets, Socket.IO, pub/sub patterns).

- Exposure to LLM integration, RAG pipelines, or AI feature development in production.

- Experience with Temporal.io or similar workflow orchestration.

- Familiarity with WhatsApp Business API, omnichannel messaging, or e-commerce integrations.

- Prior experience at a startup in the 10 - 100 person range.

What We Offer:

- Direct access to founders and product decisions.

- Competitive compensation (cash + equity discussion based on profile).

- A product that real businesses depend on every day - your work matters immediately.
