Senior Elixir Platform Lead

Fairing•New York, NY

1d•$225,000 - $260,000•Remote

About The Position

Fairing is a zero-party data attribution platform that bridges the gap between metrics and meaning. While most analytics tools tell brands what happened, we help them understand why. We capture insights customers willingly share at the moment of conversion, currently through post-purchase surveys, to solve the hardest problem in modern marketing: accurate attribution. We serve over 3,000 high-growth brands including Skims, Bombas, and Insurify, helping them make data-driven decisions about marketing attribution, particularly for hard-to-measure channels like podcasts, influencer marketing, and word of mouth. As a profitable, sustainable business, we prioritize solving real problems over chasing funding rounds. The Opportunity We're seeking a Senior Elixir Engineer to become our CTO's technical partner and eventual platform lead. This is a pivotal role for our six-person product team at a critical inflection point. You'll join as the senior-most engineer alongside our CTO and two other engineers (both strong Elixir practitioners), with a clear path to leading platform development as we scale. This position offers the unique opportunity to work as a high-impact individual contributor today while positioning yourself to lead platform architecture and team development tomorrow. Your work will directly shape how thousands of customers solve their attribution challenges and make better marketing investment decisions. About Location: While we welcome remote candidates across the Americas time zones and evaluate all candidates equally regardless of location, we have a preference for candidates based in New York City who can collaborate in-person with our CPTO and Product Manager for high-bandwidth strategic planning and architectural discussions. Remote candidates have the same opportunities for growth, leadership, and advancement. Location does not affect your trajectory to platform lead.

Requirements

Production Elixir expertise: You've built and maintained Elixir applications in production environments. You understand OTP principles, know when (and when not) to use GenServers, and can debug live systems without causing downtime.
Advanced PostgreSQL knowledge: You're comfortable optimizing complex queries, designing effective indexing strategies, and leveraging PostgreSQL features beyond basic CRUD operations (CTEs, window functions, JSONB operations, DISTINCT ON, etc.). Since we maximize PostgreSQL's capabilities rather than adding external services, deep database expertise is essential. If your PostgreSQL skills are intermediate but you're eager to deepen your expertise working with someone who's mastered it, we're interested in talking. This is an excellent opportunity to level up your database skills on real-world challenges.
Curiosity about customer problems: You're as interested in why we're building something as how. You ask questions about user needs, think about edge cases from the customer's perspective, and take pride when your work helps customers succeed.
Self-direction and autonomy: You excel in small teams where you have the autonomy to identify problems and propose solutions. You're energized by having significant responsibility and ownership.
Clear technical communication: You write readable, well-documented code and can explain technical trade-offs to both technical and non-technical stakeholders. You value clarity and simplicity in both code and communication.
Product partnership experience: You've partnered with product managers to define solutions, scope work, and establish project timelines. You can advocate for technical quality while remaining focused on customer outcomes, and you're comfortable having candid conversations about trade-offs, feasibility, and realistic deadlines.

Responsibilities

Ship Features That Solve Real Customer Problems Write production code daily and deliver features that directly impact how customers understand their marketing attribution. You'll work on systems that process millions of zero-party data points monthly and provide real-time attribution insights to major brands during their most critical sales periods. Success means customers making better decisions because of what you built.
Lead Platform Architecture with Customer Impact in Mind Own technical decision-making for our attribution platform's evolution, always connecting architectural choices to customer outcomes. You'll identify and resolve performance bottlenecks before they impact customers, design fault-tolerant systems using Elixir's supervision capabilities, and establish architectural patterns that scale with our growing customer base and increasingly sophisticated attribution models.
Establish Engineering Standards and Elevate the Team As our most senior IC, you'll help shape engineering culture through documentation practices, testing standards, and architectural patterns that will guide the team as we grow. Collaborate closely with our engineering team to establish code review standards, share expertise in advanced Elixir patterns, and act as a technical resource for complex challenges. Your guidance will help the entire team grow their skills and deliver higher-quality solutions.
Partner with Product to Bridge Strategy and Execution Collaborate closely with our Product Manager and CPTO to transform customer problems and strategic goals into well-scoped engineering initiatives. You'll evaluate technical feasibility of proposed features, break down complex initiatives into deliverable phases, and establish realistic project milestones. This partnership requires participating in product discussions to bring technical perspective to what we should build, advocating for technical quality while maintaining focus on delivering customer value, and ensuring alignment between the product roadmap and our platform's evolution.
