The Opportunity

We’re seeking a Database Performance Engineer to join our Engineering Infrastructure team at Seamless.

In this role, you’ll be responsible for optimizing database performance, scalability, reliability, and compliance across our high-traffic data systems. You’ll work closely with engineering, product, and DevOps teams to ensure seamless data flow, sub-second query times, and high availability across our PostgreSQL and OpenSearch clusters.

Your work will have a direct impact on system performance, customer experience, and operational efficiency as you identify, resolve, and prevent bottlenecks in mission-critical data environments.

Responsibilities

• Own the health, performance, and reliability of our PostgreSQL and OpenSearch environments in production.
• Design, manage, and validate backup and recovery processes, including routine backup monitoring, restore testing, and disaster recovery readiness.
• Analyze and optimize slow queries, indexing strategies, and execution plans across both PostgreSQL and OpenSearch.
• Improve database performance for large-scale datasets (1TB+), with a focus on latency, throughput, storage efficiency, and stability.
• Lead data modeling and schema design decisions to support scalable application growth and reporting needs.
• Design and optimize indexing, partitioning, and data access patterns for high-volume workloads.
• Partner with engineering to improve how applications interact with PostgreSQL and OpenSearch, including query design and performance best practices.
• Monitor database health and proactively address issues related to replication, storage growth, resource utilization, and query performance.
• Troubleshoot production incidents involving database performance, search performance, and data integrity, and drive root cause resolution.
• Recommend and implement improvements to architecture, tooling, and processes that increase scalability and reduce operational risk.

Skillset

• Strong hands-on experience managing PostgreSQL in production environments.
• Experience with OpenSearch or Elasticsearch in production, including query tuning and index optimization.
• Deep experience with query optimization, execution plan analysis, and performance tuning for large datasets.
• Strong understanding of data modeling, schema design, and indexing strategies.
• Experience supporting databases with high data volume and growth, ideally in environments with datasets of 1TB+.
• Comfortable working closely with software engineers to improve application-level data access and query efficiency.
  
  

Education & Requirements

• Bachelor’s degree in Computer Science, Engineering, or a related field (or equivalent practical experience).
• Proven experience managing and optimizing large-scale production databases.
• Strong collaboration skills with Engineering, DevOps, and Security teams.
• U.S. work authorization required (Visa Sponsorship not included).

The Opportunity

Seamless is looking for a Director of Demand Generation to own the engine that drives our growth. This role is for the strategist who has spent years decoding what actually moves the needle on pipeline and is ready to do it at scale—with a team that has your back and leadership that stays out of your way.

Your Team

You’ll lead a talented group across SEO, Content Marketing, and our Agency partners. These aren’t siloed functions; they are high-performers looking for a leader to connect the dots and point everyone toward the same North Star. You’ll also work hand-in-hand with our Revenue team to build integrated campaigns that fuel the funnel from the first touch to the final close.

What Winning Looks Like (The First 90 Days)

We don't expect perfection in three months, but we do expect momentum. Success looks like:

• Higher Quality, Not Just Higher Volume: You’ve shifted the focus to domestic, ICP-matched users who actually convert. We want the right traffic, not just more traffic.

• Sales Alignment: You and the Sales team are speaking the same language. You’ve defined what "qualified" means and built the campaigns that deliver exactly that.

• A Compound Interest Machine: You’ve moved away from one-off pushes. You’re building a repeatable, documented marketing process that doesn't break when the wind changes.

Responsibilities

What You'll Own

• The Pipeline: You set the strategy and drive execution across paid, lifecycle, and content. If it turns a lead into revenue, it’s under your purview.

• Full-Funnel Architecture: You’ll design the journey, ensuring lead routing and MQL quality are seamless (pun intended) from the moment someone raises their hand.

• The Nurture Infrastructure: You’ll manage the "brain" of our operation—segmentation, lead scoring, and behavioral automation. Whether it’s Customer.io or Salesforce, you know these tools inside out.

• Efficiency & CRO: You’ll live in the data (CAC, ROAS, CPL) and run a rigorous CRO program. You’ll test landing pages, ad creative, and email flows—scaling the wins and killing the darlings.

Who You Are

• A B2B SaaS Veteran: You have 5+ years in growth or performance marketing with the pipeline numbers to prove it.

• A "Sales-First" Marketer: You’ve earned the respect of sales teams before. They don't roll their eyes when you walk in; they ask how they can help.

• Technical & Analytical: Tools like Segment, Amplitude, and Customer.io are how you think, not just software you’ve used.

• An Agency Connoisseur: You know how to push agencies to deliver their best work and you can spot "fluff" from a mile away.

• Data-Driven, Not Ego-Driven: You test constantly and let the data decide the winner.

A Note From The Hiring Manager

"I’ll be direct: I hire people because they are better at their craft than I am. My job is to clear the path, provide the resources you need, and then get out of your way. I’m not a micro-manager; I’m a collaborator. I care about open communication and building a system that lasts. If you want to own your domain and build something that compounds, we’re going to get along great."

Skillset

• Experience: 5+ years of high-octane growth or performance marketing, specifically within B2B SaaS or high-growth tech environments.

• The Stack: You are an expert across paid channels and have deep hands-on experience with automation (Customer.io, HubSpot, Marketo) and analytics (Segment, Amplitude).

• The Playbook: You have a proven track record of scaling multi-channel campaigns and a granular understanding of funnel metrics.

• Communication: You can translate "marketing-speak" into "revenue-speak" for everyone from an SDR to the CEO.

• Bias for Action: You’d rather test, fail, and iterate in a week than spend a month planning for "perfect."

Education & Requirements

• Background: A Bachelor’s degree or equivalent real-world experience in a B2B SaaS GTM organization. You understand how marketing specifically enables and accelerates a sales team.

• The "Extras": You’ve managed marketing support for recruiting initiatives, employer branding, or job boards. You understand that "Growth" applies to our talent pipeline, too.

• Product Curiosity: You genuinely love tools like Segment, Amplitude, Unbounce, or Seamless and enjoy figuring out how to make them talk to each other to drive better data.
