We're looking for two experienced backend Software Engineers to join our Deliverability team in San Francisco. This team is responsible for the core systems that power Front - the pipeline that connects Front to the external world - which process tens of millions of events delivering emails, SMS, and other messages to and from Front quickly and reliably. You'll own critical infrastructure that our customers depend on and take on a technical leadership role within the team, building upon our deliverability systems that need to be performant, scalable and reliable, all at once.

What will you be doing?

- Serve as a technical lead on the Deliverability team, driving the architecture and execution of major infrastructure and product projects
- Own and improve high-volume email infrastructure and decisioning systems spanning ingestion, routing, and outbound delivery, driving deliverability outcomes at scale
- Own key services that power Front and lead architectural evolutions to build for reliability and scale
- Collaborate with other systems and infrastructure teams to build upon next-generation architecture
- Collaborate closely with product managers, product designers and other engineers to conceptualize, build, and test new product features

What skills and experience do you need?

- 5+ years of professional software engineering experience
- Strong experience building and operating high-scale, distributed backend systems
- Comfort owning complex systems and making architectural decisions with real production impact
- A collaborative, low-ego approach to engineering and cross-team partnerships
- Experience with on-call responsibilities and a strong sense of ownership over system reliability
- Product mindset, building scalable and extensible solutions that meet customer requirements
- Fluency in a dynamic language like Javascript (Typescript), Python, Ruby, or similar
- Strong track record of launching and delivering projects of significant complexity and high level of ambiguity
- Experience architecting, deploying and operating asynchronous work queues, high-volume storage systems, or high-throughput systems
- Understand the trade-offs in employing different engineering solutions to a problem, valuing pragmatism over idealism
- Ability to thrive in a dynamic, fast-paced, collaborative, and high-growth environment

## Nice to have -

- Prior experience at a B2B SaaS or customer communications company
- Familiarity with email sending at high volume (millions of messages/day)
- Experience with DNS infrastructure
- Experience working on software systems built on Amazon Web Services
- Deep knowledge of the email stack and assorted RFCs
- Experience with anti-spam infrastructure to prevent bad actors from exploiting an email service
- Built deep integrations with an email delivery service like SendGrid, MailGun, Mandrill or SparkPost
- Experience with Gmail or Office 365 APIs
- Experience with Kafka

- **Mission**: "Keep every team, tool, and customer conversation in sync so companies can scale without losing connection."

## Products & Services
- **Front AI (AI Command Center)**: AI-powered automation that handles complex requests (not just simple FAQs) – including automated responses, agent assistance, and quality analysis across the entire customer operation.
- **Shared Inbox**: Collaborative inbox where teams can assign, comment, route, and manage customer conversations across email, text, chat, and other channels from a single view.
- **Integrations (130+)**: No-code connections with popular business tools (e.g., Slack, Salesforce, Jira, etc.) to bring full context into every conversation.

- **Growth Signals**: 300+ employees across 5 offices (San Francisco, Paris, Dublin, Chicago, Santiago); 9,300+ customers; 4.7 stars / 2,000+ reviews on G2; repositioned around AI in 2025; new CEO Dan O'Connell (ex-Dialpad) driving growth past $100M ARR

## Competitive Advantages

- Unified view across support, success, sales, and account management – eliminating the "coordination tax" of switching tools
- Deep integration ecosystem (130+) and no‑code workflow builder that adapts to each customer's unique processes

## Strategic Focus

- **Scaling operations**: Continuing to grow ARR while maintaining capital‑efficient growth (CFO Meredith Finn from Salesforce Ventures/Twitter)
